Locally advanced tumor with involvement of surrounding tissues and organs is a common situation in pelvic malignancies. Up to 10% of newly diagnosed rectal cancer cases infiltrate to adjacent tissues and organs. Satisfactory resection margins obtained by pelvic exenteration can achieve a 5-year survival rate similar to cases that without adjacent tissue invasion. The 5-year survival rate of patients with locally recurrent pelvic malignancies is almost zero if they are treated only with radiotherapy and chemotherapy. To obtain negative margins through pelvic exenteration is the only chance for a long-term survival of these patients. However, pelvic exenteration is a complicated procedure with higher morbidity and mortality. The development of fascia anatomy enables surgeons to have a deeper understanding and comprehensive application of pelvic fasciae. Meanwhile, the improvement of laparoscopic technology provides a clearer view for surgeons and enables the application of minimally invasive techniques in complex pelvic exenteration. The fascial space priority approach is based on the fascia anatomy of pelvis and giving priority to the separation of the pelvic avascular fascial spaces, which provides a reproducible surgical approach for complex pelvic exenteration.

Objective: To propose a new staging system for presacral recurrence of rectal cancer and explore the factors influencing radical resection of such recurrences based on this staging system. Methods: In this retrospective observational study, clinical data of 51 patients with presacral recurrence of rectal cancer who had undergone surgical treatment in the Department of Gastrointestinal Surgery, Peking University People's Hospital between January 2008 and September 2022 were collected. Inclusion criteria were as follows: (1) primary rectal cancer without distant metastasis that had been radically resected; (2) pre-sacral recurrence of rectal cancer confirmed by multi-disciplinary team assessment based on CT, MRI, positron emission tomography, physical examination, surgical exploration, and pathological examination of biopsy tissue in some cases; and (3) complete inpatient, outpatient and follow-up data. The patients were allocated to radical resection and non-radical resection groups according to postoperative pathological findings. The study included: (1) classification of pre-sacral recurrence of rectal cancer according to its anatomical characteristics as follows: Type I: no involvement of the sacrum; Type II: involvement of the low sacrum, but no other sites; Type III: involvement of the high sacrum, but no other sites; and Type IV: involvement of the sacrum and other sites. (2) Assessment of postoperative presacral recurrence, overall survival from surgery to recurrence, and duration of disease-free survival. (3) Analysis of factors affecting radical resection of pre-sacral recurrence of rectal cancer. Non-normally distributed measures are expressed as median (range). The Mann-Whitney U test was used for comparison between groups. Results: The median follow-up was 25 (2-96) months with a 100% follow-up rate. The rate of metachronic distant metastasis was significantly lower in the radical resection than in the non-radical resection group (24.1% [7/29] vs. 54.5% [12/22], χ2=8.333, P=0.026). Postoperative disease-free survival was longer in the radical resection group (32.7 months [3.0-63.0] vs. 16.1 [1.0-41.0], Z=8.907, P=0.005). Overall survival was longer in the radical resection group (39.2 [3.0-66.0] months vs. 28.1 [1.0-52.0] months, Z=1.042, P=0.354). According to univariate analysis, age, sex, distance between the tumor and anal verge, primary tumor pT stage, and primary tumor grading were not associated with achieving R0 resection of presacral recurrences of rectal cancer (all P>0.05), whereas primary tumor pN stage, anatomic staging of presacral recurrence, and procedure for managing presacral recurrence were associated with rate of R0 resection (all P<0.05). According to multifactorial analysis, the pathological stage of the primary tumor pN1-2 (OR=3.506, 95% CI: 1.089-11.291, P=0.035), type of procedure (transabdominal resection: OR=29.250, 95% CI: 2.789 - 306.811, P=0.005; combined abdominal perineal resection: OR=26.000, 95% CI: 2.219-304.702, P=0.009), and anatomical stage of presacral recurrence (Type III: OR=16.000, 95% CI: 1.542 - 166.305, P = 0.020; type IV: OR= 36.667, 95% CI: 3.261 - 412.258, P = 0.004) were all independent risk factors for achieving radical resection of anterior sacral recurrence after rectal cancer surgery. Conclusion: Stage of presacral recurrences of rectal cancer is an independent predictor of achieving R0 resection. It is possible to predict whether radical resection can be achieved on the basis of the patient's medical history.

The treatment of locally advanced rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) has been a difficulty and challenge in the field of advanced rectal cancer, while pelvic exenteration (PE), as an important way to potentially achieve radical treatment of LARC and LRRC, has been shown to significantly improve the long-term prognosis of patients. The implementation of PE surgery requires precise assessment of the extent of invasion of LARC or LRRC and adequate preoperative preparation through multidisciplinary consultation before surgery. The lateral pelvis involves numerous tissues, blood vessels, and nerves, and resection is most difficult, and the ureteral and Marcille triangle approaches are recommended; while the supine transabdominal approach combined with intraoperative change to the prone jacket position facilitates adequate exposure of the surgical field and enables precise overall resection of the bony pelvis and pelvic floor muscle groups invaded by the tumor. Empty pelvic syndrome has always been an major problem to be solved during PE. The application of extracellular matrix biological mesh to reconstruct pelvic floor defects and isolate the abdominopelvic cavity is expected to reduce postoperative pelvic floor related complications. Reconstruction of the urinary system and important vessels after PE is essential, and the selection of appropriate reconstruction methods helps to improve the patient's postoperative quality of life, while more new methods are also being continuously explored.

Leiomyosarcoma of urinary bladder (LMS-UB) is a highly malignant mesenchymal tumor, accounting for less than 0.5% of all bladder malignancies, with a predominant clinical presentation of hematuria. Here we report a case of low-grade LMS-UB. A 44-year-old male patient was admitted to the hospital with urodynia for 2 weeks. The patient's pelvis CT showed a mass on the right part of the bladder. For this reason, he was initially diagnosed with bladder cancer. We performed a robot-assisted laparoscopic enucleation of the bladder tumor and low-grade LMS-UB was diagnosed with the histopathological examination. He underwent 5 cycles of adjuvant chemotherapy after surgery. At 19months postoperative follow-up, the patient had no symptoms, recurrence, or distant metastasis. There is no report on the treatment of LMS-UB with minimally invasive enucleation worldwide. This case provides a new comprehensive treatment method of enucleation combined with adjuvant chemotherapy for early low-grade LMS-UB to reduce complications and improve patients' quality of life after surgery.

El tumor mesenquimático fosfatúrico es una entidad clinicopatológica sumamente infrecuente. Además de provocar dolor óseo insidioso y polimialgias, se acompaña de alteraciones del metabolismo fosfocálcico de difícil manejo clínico. El abordaje multidisciplinario resulta la clave del éxito en esta enfermedad. Presentamos una paciente de 52 años de edad con antecedente de tumor mesenquimático fosfatúrico en la hemipelvis derecha con extensión a la cadera homolateral de 10 años de evolución. Clínicamente presentaba osteomalacia oncogénica (hipofosfatemia e hiperfosfaturia) que no se corregía, pese a un agente de última generación, el burosumab, un inhibidor del factor de crecimiento fibroblástico 23, que aumenta la reabsorción tubular renal de fosfatos. En un comité multidisciplinario, se decidió la resección con márgenes oncológicos y se logró una mejoría clínica franca. Comunicamos este caso, debido a que es un cuadro infrecuente. Nivel de Evidencia: IV

Phosphaturic mesenchymal tumor (PMT) is an infrequent clinicopathological entity. It presents insidious bone pain and polymyalgia, accompanied by alterations in calcium and phosphorus metabolism that are difficult to resolve clinically. A multidisciplinary approach is a key to success in this pathology. We present the case of a 52-year-old female patient with a 10-year history of PMT in the right hemipelvis with ipsilateral hip extension. From the clinical point of view, she presented oncogenic osteomalacia (hypophosphatemia and hyperphosphaturia) that did not correct despite being administered the latest generation medication, burosumab, an FGF-23 inhibitor that increases renal tubular phosphate reabsorption. Resection with oncological margins was decided by a multidisciplinary committee resolving her clinical condition. Due to the rarity of this pathology, we decided to report the case.

Objective: Total mesorectal resection (TME) is difficult to perform for rectal cancer patients with anatomical confines of the pelvis or thick mesorectal fat. This study aimed to evaluate the ability of pelvic dimensions to predict the difficulty of TME, and establish a nomogram for predicting its difficulty. Methods: The inclusion criteria for this retrospective study were as follows: (1) tumor within 15 cm of the anal verge; (2) rectal cancer confirmed by preoperative pathological examination; (3) adequate preoperative MRI data; (4) depth of tumor invasion T1-4a; and (5) grade of surgical difficulty available. Patients who had undergone non-TME surgery were excluded. A total of 88 patients with rectal cancer who underwent TME between March 2019 and November 2021 were eligible for this study. The system for scaling difficulty was as follows: Grade I, easy procedure, no difficulties; Grade II, difficult procedure, but no impact on specimen quality (complete TME); Grade III, difficult procedure, with a slight impact on specimen quality (near-complete TME); Grade IV: very difficult procedure, with remarkable impact on specimen quality (incomplete TME). We classified Grades I-II as no surgical difficulty and grades III-IV as surgical difficulty. Pelvic parameters included pelvic inlet length, anteroposterior length of the mid-pelvis, pelvic outlet length, pubic tubercle height, sacral length, sacral depth, distance from the pubis to the pelvic floor, anterior pelvic depth, interspinous distance, and inter-tuberosity distance. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with the difficulty of TME, and a nomogram predicting the difficulty of the procedure was established. Results: The study cohort comprised 88 patients, 30 (34.1%) of whom were classified as having undergone difficult procedures and 58 (65.9%) non-difficult procedures. The median age was 64 years (56-70), 51 patients were male and 64 received neoadjuvant therapy. The median pelvic inlet length, anteroposterior length of the mid-pelvis, pelvic outlet length, pubic tubercle height, sacral length, sacral depth, distance from the pubis to the pelvic floor, anterior pelvic depth, interspinous distance, and inter-tuberosity distance were 12.0 cm, 11.0 cm, 8.6 cm, 4.9 cm, 12.6 cm, 3.7 cm, 3.0 cm, 13.3 cm, 10.2 cm, and 12.2 cm, respectively. Multivariable analyses showed that preoperative chemoradiotherapy (OR=4.97,95% CI: 1.25-19.71, P=0.023), distance between the tumor and the anal verge (OR=1.31, 95% CI: 1.02-1.67, P=0.035) and pubic tubercle height (OR=3.36, 95% CI: 1.56-7.25, P=0.002) were associated with surgical difficulty. We then built and validated a predictive nomogram based on the above three variables (AUC = 0.795, 95%CI: 0.696-0.895). Conclusion: Our research demonstrated that our system for scaling surgical difficulty of TME is useful and practical. Preoperative chemoradiotherapy, distance between tumor and anal verge, and pubic tubercle height are risk factors for surgical difficulty. These data may aid surgeons in planning appropriate surgical procedures.

Introducción: La articulación sacroilíaca es el origen del dolor en el 10-25% de los pacientes con lumbalgia mecánica. Si no hay traumatismos, tumores, enfermedades metabólicas ni colagenopatías, su papel en la fisiopatología del dolor lumbar aún no está completamente dilucidado. El objetivo fue estudiar la anatomía sagital de la pelvis a través de la medición de la incidencia pélvica en pacientes con dolor sacroilíaco en el ámbito laboral frente a personas asintomáticas. Materiales y métodos: Estudio analítico, observacional, retrospectivo de pacientes con dolor sacroilíaco diagnosticados mediante un bloqueo guiado por tomografía computarizada en un centro de patología laboral, entre enero de 2015 y diciembre de 2018. El grupo de comparación fue una muestra aleatoria de personas sin enfermedad de la pelvis o lumbosacra estudiados con tomografía computarizada de pelvis y columna durante el mismo período. Resultados: La incidencia pélvica media en pacientes con dolor sacroilíaco fue de 52,57 (DE 9) y 46,52 (DE 9) en el grupo de personas sanas. La diferencia fue estadísticamente significativa con valores mayores de incidencia pélvica en pacientes con dolor sacroilíaco (p 0,042). Conclusión: Los pacientes con dolor sacroilíaco presentaron una mayor incidencia pélvica que las personas sanas, con una diferencia estadísticamente significativa en nuestro estudio.

Introduction: The sacroiliac joint causes pain in 10 to 25% of patients with mechanical low back pain or symptoms radiating to the lower limbs. In the absence of trauma, metabolic disease, and collagen disease, its role in the pathophysiology of low back pain is not yet fully understood. The objective is to study the sagittal pelvic anatomy through the measurement of pelvic incidence (PI) in patients with sacroiliac pain in the workplace compared to asymptomatic patients. Materials and methods: A retrospective observational analytical study of adult patients with sacroiliac pain diagnosed with CT-guided block in an occupational pathology center during January 2015 and December 2018. The comparison group was a random sample of patients without pelvic or lumbosacral pathology studied with CT of the pelvis and spine during the same period. Results: The mean PI in patients with sacroiliac pain was 52.57 (SD 9) and 46.52 (SD 9) in the group of healthy patients. The difference was statistically significant with the higher PI values in patients with sacroiliac pain (p 0.042). Conclusion: Patients with sacroiliac pain had a higher pelvic incidence than healthy patients, with a statistically significant difference in our study. Level of Evidence: IV

INTRODUCCIÓN: En la endometriosis el compromiso intestinal afecta hasta al 12% de las pacientes, comprometiendo al recto y a la unión rectosigmoidea en el 90% de los casos. OBJETIVO: Describir la experiencia del equipo de Coloproctología y Ginecología de Clínica Alemana de Santiago en el tratamiento quirúrgico de la endometriosis pélvica profunda con compromiso colorrectal. MATERIAL Y MÉTODOS: Estudio retrospectivo a partir de la base de datos de pacientes con endometriosis tratados entre enero del año 2015 y abril de 2018. Los criterios de inclusión fueron pacientes con clínica de endometriosis pélvica profunda, que tuviesen compromiso colorrectal y hayan sido tratados con shaving rectal, resección discoide o resección segmentaria. Se revisaron fichas clínicas electrónicas, protocolos operatorios y biopsias definitivas. RESULTADOS: Se reclutaron 25 pacientes con una mediana de edad de 35 años. El síntoma principal de consulta fue dismenorrea y el síntoma digestivo más frecuente fue disquecia. En 8 pacientes se realizó un shaving rectal, en 7 una sigmoidectomía, en 9 una resección discoide y en 1 paciente una tiflectomía. La complicación posoperatoria reportada fue la hemorragia digestiva baja en 4 pacientes (Clavien-Dindo I y IIIa). Con una mediana de seguimiento de 13 meses, a la fecha 3 pacientes se les ha diagnosticado algún tipo de recidiva. CONCLUSIÓN: Es importante que la cirugía a realizar, garantice una morbilidad y recurrencia baja. Los resultados en nuestro centro son alentadores, lo que nos hace creer que el tratamiento quirúrgico podría ser una buena alternativa en la endometriosis pélvica profunda con compromiso colorrectal.

INTRODUCTION: In endometriosis, intestinal involvement affects up to 12% of patients, compromising the rectum and the rectosigmoid junction in 90% of cases. AIM: Describe the experience of the Coloproctolgy and Gynecology Team of the Clínica Alemana de Santiago in the surgical treatment of deep pelvic endometriosis with colorectal involvement. MATERIAL AND METHODS: Retrospective study based on the database of patients with endometriosis treated between January 2015 and April 2018. The inclusion criteria were patients with deep pelvic endometriosis clinic, who had colorectal involvement and who had been treated with rectal shaving, discoid resection or segmental resection. Electronic clinical records, operative protocols and definitive biopsies were reviewed. RESULTS: Twenty-five patients with a median age of 35 years were recruited. The main symptom of consultation was dysmenorrhoea and the most frequent digestive symptom was dyschezia. In 8 patients a rectal shaving was performed, in 7 a sigmoidectomy, in 9 a discoid resection and in 1 patient a tiflectomy. The only reported post-operative complication was low gastrointestinal bleeding in 4 of the 25 patients (Clavien-Dindo I and IIIa). A median follow-up of 13 months was achieved, to date 3 patients have been diagnosed with some type of recurrence. CONCLUSION: It is important that the surgery to be performed guarantees low morbidity and recurrence. The results in our center are encouraging, which makes us believe that surgical treatment could be a good alternative in deep pelvic endometriosis with colorectal involvement.

Actinomycosis is a chronic or subacute bacterial infection characterized by large abscess formation, caused mainly by the gram-positive non-acid-fast, anaerobic, or microaerophilic/capnophilic, obligate parasites bacteria from the genus. Although pelvic inflammatory disease is an entity associated with the longstanding use of intrauterine devices (IUDs), actinomycosis is not one of the most frequent infections associated with IUDs. We present the case of a 43-year-old female patient who was referred to the emergency facility because of a 20-day history of abdominal pain with signs of peritoneal irritation. Imaging exams revealed collections confined to the pelvis, plus the presence of an IUD and evidence of sepsis, which was consistent with diffuse peritonitis. An exploratory laparotomy was undertaken, and a ruptured left tubal abscess was found along with peritonitis, and a huge amount of purulent secretion in the pelvis and abdominal cavity. Extensive lavage of the cavities with saline, a left salpingo-oophorectomy, and drainage of the cavities were performed. The histopathological examination of the surgical specimen revealed an acute salpingitis with abscesses containing sulfur granules. Therefore, the diagnosis of abdominal and pelvic actinomycosis was made. The postoperative outcome was troublesome and complicated with a colocutaneous fistula, which drained through the surgical wound. A second surgical approach was needed, requiring another extensive lavage and drainage of the recto-uterine pouch, plus the performance of a colostomy. Broad-spectrum antibiotics added to ampicillin were the first antimicrobial regimen followed by 4 weeks of amoxicillin during the outpatient follow-up. The patient satisfactorily recovered and is already scheduled for the intestinal transit reconstitution.

OBJECTIVE: The aim of this paper was to describe the operative details for en bloc removal of the adnexal tumor, uterus, pelvic peritoneum, and rectosigmoid colon with colorectal anastomosis in advanced epithelial ovarian cancer patients with widespread pelvic involvement. METHODS: The patient presented with good performance status and huge pelvic tumor extensively infiltrating into adjacent pelvic organs and obliterating the cul-de-sac. The patient underwent en bloc pelvic resection as primary cytoreductive surgery. En bloc pelvic resection procedure is initiated by carrying a circumscribing peritoneal incision to include all pan-pelvic disease within this incision. After retroperitoneal pelvic dissection, the round ligaments and infundibulopelvic ligaments are divided. The ureters are dissected and mobilized from the peritoneum. After dissecting off the anterior pelvic peritoneum overlying the bladder with its tumor nodules, the bladder is mobilized caudally and the vesicovaginal space is developed. The uterine vessels are divided at the level of the ureters, and the paracervical tissues (or parametria) are divided. The proximal sigmoid colon is divided above the most proximal extent of gross tumor using a ligating and dividing stapling device. The sigmoid mesentery is ligated and divided including the superior rectal vessels. The pararectal and retrorectal spaces are further developed and dissected down to the level of the pelvic floor. The posterior dissection is progressed and moves to the right and then to the left of the rectum. The rectal pillars including the middle rectal vessels are ligated and divided. Hysterectomy is completed in a retrograde fashion. The distal rectum is divided using a linear stapler. The specimen is removed en bloc with the uterus, adnexa, pelvic peritoneum, rectosigmoid colon, and tumor masses leaving a macroscopically tumor-free pelvis. Colorectal anastomosis was completed using stapling device. RESULTS: En bloc pelvic resection was performed by total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic peritonectomy, and rectosigmoid colectomy with colorectal anastomosis using a stapling device. Complete clearance of pelvic disease leaving no gross residual disease was possible using en bloc pelvic resection. CONCLUSION: En bloc pelvic resection is effective for achieving maximal cytoreduction with the elimination of the pelvic disease in advanced primary ovarian cancer patients with extensive pelvic organ involvement.

PURPOSE: The aim of our study was to assess the influence of perioperative blood transfusion (PBT) on survival outcomes following radical cystectomy (RC) and pelvic lymph node dissection (PLND). MATERIALS AND METHODS: We reviewed and analyzed the clinical data of 432 patients who underwent RC for bladder cancer from 1991 to 2012. PBT was defined as the transfusion of allogeneic red blood cells during RC or postoperative hospitalization. RESULTS: Of all patients, 315 patients (72.9%) received PBT. On multivariate logistic regression analysis, female gender (p=0.015), a lower preoperative hemoglobin level (p=0.003), estimated blood loss>800 mL (p4 packed red blood cell units was an independent predictor of overall survival (p=0.007), but not in cancer specific survival. CONCLUSIONS: Our study was not conclusive to detect a clear association between PBT and survival after RC. However, the efforts should be made to continue limiting the overuse of transfusion especially in patients who are expected to have a high probability of PBT, such as females and those with a low preoperative hemoglobin level and history of neoadjuvant chemotherapy.

A 40-year-old female presented with bilateral lower limb weakness with bladder and bowel incontinence. MRI study revealed a destructive lesion involving the D7 vertebral body and a large tumor in the gluteal muscles invading the right iliac blade. A histological examination demonstrated a tumor comprising of rounded to ovoid pleomorphic epithelioid cells with marked cytological atypia. Tumor cells expressed CD 34, vimentin and focally pancytokeratin but were negative for CD31, EMA, SMA, WT1 and LCA. A D6-7 laminectomy with posterior decompression was done. Postoperatively, external beam radiotherapy was given. However, the patient deteriorated rapidly with no neurological improvement. Epitheiliod sarcomas and their recently described proximal variant, by virtue of being an exceedingly unusual tumor are often misdiagnosed or diagnosed late beyond the stage of salvage. This report highlights the histopathology and that need to be analyzed to correctly diagnose this entity

OBJECTIVE: The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI). MATERIALS AND METHODS: Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist. IFs were classified according to organ or system (liver, gallbladder, kidney, bladder, uterus, ovary, lymph node, intestine and aorta). The rate of reporting of a range of IF was examined. The outcome of each patient's treatment was evaluated based on review of hospital records and by telephone interviews. RESULTS: A total of 253 IFs were found in 241 patients (18.8% of 1278). Among these, clinically significant IFs (n = 34) included: 2 renal masses (0.15%), 2 aortic aneurysms (0.15%), 2 cases of hydronephrosis (0.15%), 11 adrenal masses (0.86%), 7 lymphadenopathies (0.55%), 6 cases of endometrial or cervical thickening (0.47%), 1 liver hemangioma (0.08%), 1 pelvic fluid (0.08%) and 2 ovarian dermoid cysts (0.15%). Overall, 28% (71/253) of IFs were included in the clinical reports, while clinically significant findings were reported in 41% (14/34) of cases. CONCLUSION: Extraspinal IFs are commonly detected during a routine lumbar MRI, and many of these findings are not clinically significant. However, IFs including clinically important findings are occasionally omitted from formal radiological reports.

Background: Brown tumors of bones are an uncommon manifestation of hyperparathyroidism. Case report: We report a 35 years old male presenting with pain and paresis of the left superior limb. Part of his humerus was excised due to a diagnosis of a giant cell tumor. He was admitted again to the hospital due to pelvic pain, malaise and constipation. A right cervical nodule was found. Laboratory evaluation confirmed the presence of a hyperparathyroidism. The biopsy of the pelvic lesion disclosed a brown tumor. The patient was subjected to a parathyroidectomy and the pathological study of the surgical piece showed a right parathyroid adenoma and a right thyroid papillary micro carcinoma. In the postoperative period the patient had a hungry bone syndrome, which was adequately treated.

Introducción: La paratohormona es una hormona encargada de la homeostasis del calcio, el hiperparatiroidismo es una patología con manifestaciones renales y óseas, el Tumor Pardo es una rara presentación de esta enfermedad. Caso clínico: Hombre de 35 años con dolor y paresia en extremidad superior izquierda, fue resecado parte del húmero por un diagnóstico de Tumor de Células Gigantes; reingresa con dolor pélvico derecho, malestar general, astenia y estreñimiento. Se descubre un nódulo cervical derecho e hipersensibilidad en la pelvis derecha. Los exámenes de laboratorio muestran hiperparatiroidismo; la biopsia de la lesión pélvica es diagnóstica de Tumor Pardo, encontrándose además una hipercaptación paratiroidea derecha. Operado, el diagnóstico histopatológico fue: Adenoma paratiroideo derecho y un micro carcinoma papilar tiroideo; en el post-operatorio desarrolló un Síndrome de Bone Hunger, el cual fue superado y dado de alta. Discusión y conclusiones: El Tumor Pardo no es una verdadera neoplasia; producido por intensa actividad osteoclástica, tiene características histológicas y radiológicas inespecíficas y su diagnóstico se realiza por datos clínicos y bioquímicos. El hiperparatiroidismo puede llevar a la formación de Tumores Pardos; se sugiere realizar estudios de la glándula tiroides en pacientes con hiperparatiroidismo.

Hydatid disease or echinococcosis is a common parasitic disease of human and bovine, caused by infection with larva of the cestode echinococcus. Liver is the most common organ that is involved in this disease. Pelvic involvement and neurological symptoms, due to mass effect of pelvic involvement, in lower extremities are very uncommon manifestations of the disease. A forty six year old man was referred to clinic of surgery at Ghaem Hospital, Medical University of Mashhad, Iran. The patient complained about weakness and motor impairment in right lower extremity accompanied by numbness and radicular pain over past two months. Physical examination demonstrated muscular atrophy and reduced muscular strength in right lower extremity. Computed tomography and ultrasonographic studies showed a cystic mass in right side of the pelvic cavity with extention to the sciatic notch and another cystic mass in right gluteal region. Surgical operation revealed a cystic mass deep in pelvic cavity with the extention to the right sciatic notch with compression of nerve roots. The cystic mass was contained of daughter cysts which confirmed the diagnosis of hydatid cyst disease. This diagnosis was confirmed by pathologic assessment. Although uncommon, but hydatid disease can involve the pelvic cavity and make a pelvic, usually cystic, mass; that can make compression on nerve roots and so making neurologic symptoms in lower extremities. So in endemic areas for hydatid disease, such as Iran, pelvic hydatid cysts should be considered as a possible differential diagnosis in patients presenting with the sciatic pain and neurological manifestations in whom a pelvic mass has been found too.

Nuestro objetivo es cuestionar la definiciónde los estadios II A - II B - II C en pacientes con diagnóstico de cáncer de testículo (seminoma clásico). La evaluación de los ganglios linfáticos retroperitoneales se realiza con una TAC de abdomen y pelvis, siendo este un aspecto importante de la estadificación clínica y la planificación del tratamiento de cáncer de testículo. El seminoma en estadio II se divide en enfermedad voluminosa (ganglios lumbo-aórticos mayor de 5 cm: II C) y no voluminosa (ganglios lumbo-aórticos menor de 5 cm: II AIIB). Estas definiciones de cm son variables, para algunos autores consideran el eje más largo, y para otros, es el eje que corresponde al diámetro transversal de los ganglios comprometidos. El tratamiento estándar va a depender del tamaño de las adenopatías. Se efectúa una revisión de la estadificación del cáncer de testículo. El N no debería definirse en función del largo del eje mayor de los ganglios retroperitoneales, debería efectuarse por el volumen de los mismos. El volumen de las adenopatías puede definirse en forma precisa utilizando una TAC, las imágenes obtenidas se introducen en un sistema de planificación 3 D, se definen los ganglios retroperitoneales (contornean o dibujan) y luego se puede establecer conexactitud del volumen de las misma

The aim of this paper is to question the definition for phases II A- II B- II C, en patients with testicular cancer (classic seminoma) diagnosis. The evaluation of retroperitoneal lymphatic glands is performed with an abdomen and pelvis CAT, which represents an important study in the stage clinical staging and in the planning for the treatment of the testicular cancer. The phase II seminoma is divided into bulky disease (lumbo-aortic glands bigger than 5 cm: II C) and non bulky disease (lumbo-aortic glands smaller than 5 cm: II A-II B). These sizes are variable as some authors take into account the longest axis while for others the axis to take into account is that corresponding to the transversal diameter of the affected glands. The standard treatment will depend on the lymphatic node size. A revision of the testicular cancer phases is carried out. Is the following N, should not be defined according to the retroperitoneal glands and the biggest axis length, but according to their volume. The lymphatic nodes volume can be precisely and defined through the use of CAT, where they obtained images are loaded into a 3D planning system, the retroperitoneal glands are defined (outlined or drawn) and afterwards the volume can be exactly defined for us

A endometriose é definida como a presença de glândulas endometriais e estroma fora da cavidade uterina. Essa doença, comum nas mulheres, é geralmente observada durante os anos reprodutivos. Embora a pelve seja o sítio mais comum da endometriose em mulheres, a localização extrapélvica é menos frequente e ainda mais difícil de diagnosticar, em decorrência das apresentações distintas. Neste artigo é descrito um caso de endometriose de cicatriz da parede abdominal.

Endometriosis is defined as the presence of endometrial glands and stroma outside the uterine cavity. This disease is commonly observed in women, particularly those of reproductive age. The pelvis is the most common location for endometriosis. On the other hand, extrapelvic endometriosis, which is less common, is more difficult to diagnose because of the extreme differences in its presentation. In this article, we describe our experience of a case of endometriosis in an abdominal wall scar.
