Initial Clinical Experience of Pure Single-Incision Robotic Right Hemicolectomy with da Vinci SP Platform

The da Vinci SP Surgical System (dVSP; Intuitive Surgical, Sunnyvale, CA, USA) was introduced to perform pure single-incision surgery in 2018. This new surgical platform demonstrated favorable performance compared with the positive aspect of single-incision laparoscopic surgery and robot surgery. To date, its use has mainly been in urological and gynecological procedures. We report a case of successful robotic single-incision right hemicolectomy for cecal cancer with the dVSP.

Skip metastasis to portocaval and retropancreatic space in T2 cecal cancer without regional and principle lymph node involvement

Lymph node metastasis in early colon cancer is relatively low. Furthermore, skip metastasis beyond principle lymph node is very rare. This is a case of early cecal cancer with skip metastasis to portocaval and retropancreatic space, without regional lymph node metastasis. A 69-year-old female diagnosed as cecal adenocarcinoma. The imaging study revealed as early cecal cancer without enlargement of regional lymph node. However, there is enlargement of portocaval lymph node and high fluorodeoxyglucose (FDG) uptake in positron emission tomography scan image. Right hemicolectomy with extended lymph node dissection was done including retropancreatic, portocaval and hepatoduodenal ligament lymph node. Though whole abdominal cavity exploration was done, there was no evidence of other synchronous cancer. The final pathologic findings revealed the poorly differentiated adenocarcinoma with invasion of submucosal layer and focally superficial layer of muscularis propria. Two of total 27 lymph nodes were involved by metastastatic adenocarcinoma which were from portocaval and retropancreatic space. The detailed preoperative imaging study could find unexpected lymph node metastasis beyond range of routine lymph node dissection. Even though the preoperative clinical stage is relatively early, the detailed and sufficient evaluation for clinical and imaging findings is important not to ignore skip metastasis.

A Case of Toxocariasis in a Patient with Cecal Cancer Mimicking Hepatic Metastasis / 대한내과학회지

Toxocariasis is a common helminth infection and the most common cause of peripheral blood eosinophilia. The clinical presentation of liver toxocariasis is often confused with primary or metastatic hepatic tumors. Here, we report on a 52-year-old man admitted with cecal cancer and eosinophilia. Computerized tomography (CT) scans revealed multiple lesions with peripheral enhancement in the liver, and T1- and T2-weighted images revealed isointensity. The patient underwent right hemicolectomy and an exploratory laparotomy with a liver biopsy. Resection of the cecal specimen revealed an adenocarcinoma, while the liver biopsy revealed an eosinophilic abscess with no evidence of malignancy. A serologic test showed a marked increase in specific immunoglobulin G antibody concentrations against Toxocara canis and daily antiparasitic treatment with albendazole (800 mg per day for 7 days) was initiated. Follow-up CT scans indicated that all liver masses and eosinophilia were resolved.

Simultaneous Laparoscopy-Assisted Resection for Colorectal Cancer and Metastases / 고신대학교의과대학학술지

With advancement of minimal invasive surgery, a simultaneous laparoscopy-assisted resection for colorectal cancer and metastasis has become feasible. Hence, we report three cases of simultaneous laparoscopic surgery for colorectal cancer with liver or lung metastasis. In the first case, laparoscopic right hemicolectomy and left lateral segmentectomy of liver was performed for ascending colon cancer and liver metastasis. In the second case, laparoscopic right hemicolectomy and wedge resection of right lower lung was performed for cecal cancer and lung metastasis. In the third case, laparoscopic right hemicolectomy and wedge resection of left lower lung was performed for ascending colon cancer and lung metastasis. In the first two cases, patients quickly returned to normal activity. In the third case, postoperative bleeding was observed, but spontaneously stopped. There was no postoperative mortality. Simultaneous laparoscopic surgery represents a feasible option for colorectal cancer with metastases on the other organs.

Neoplasias malignas primarias del apéndice cecal: estudio comparativo entre 2 hospitales regionales / Primary malignant tumors of appendix

Background: Primary malignant tumors of appendix are uncommon and usually found during the pathological examination of surgical pieces of appendectomies. Aim: To report the clinical and pathological features of appendiceal malignant tumors. Material and Methods: Review of medical and pathological reports of patients subjected to an appendectomy between 1998 and 2006 in two regional hospitals. Results: Fifteen appendiceal malignant tumors in 2,687 pathological studies were detected (0.55 percent of all studies) in one hospital. In the other 10 tumors were detected in 4,939 studies (0.2 percent). Nine bearers of tumors were male. In each hospital 93 and 80 percent of patients had an acute appendicitis, respectively. The pathology report informed a neuroendocrine tumor in 87 and 70 percent of patients of each hospital, respectively, followed by non-Hodgkin lymphoma and adenocarcinoma. In nine patients a staging study was performed. Four patients died during follow up, one of them due to tumor disseminations. Conclusions: Although appendiceal tumors appear in only 0.3 percent of all appendectomies, the pathological study of the excised appendix is fundamental for the diagnosis.

Introducción: Las neoplasias malignas primarias del apéndice cecal son infrecuentes, generando un gran problema diagnóstico, evidenciándose la mayoría de las veces de forma incidental en el estudio histopatológico (EH). Nuestro objetivo es analizar y comparar las características epidemiológicas, clínicas, quirúrgicas e histológicas de las neoplasias malignas primarias apendiculares en dos hospitales regionales de alta prevalencia en cáncer. Materiales y Métodos: Se realizó un estudio retrospectivo de serie de casos, se seleccionó pacientes con diagnóstico de neoplasia apendicular maligna en los Hospitales Regionales de Antofagasta (HRA) y Valdivia (HRV) entre 1998-2006, se excluyeron pacientes con neoplasias malignas secundarias. Los datos se analizaron mediante estadística descriptiva y χ2. Resultados: En HRA se pesquisaron 15 (0,55 por ciento) casos de tumores malignos primarios en 2.687 EH, en HRV se encontraron 10 (0,20 por ciento) casos en 4.939 EH. Siendo el universo muestral de 25 pacientes. En HRA, 8 fueron en hombres y 7 en mujeres, con edad media de 30 años. En HRV fueron 1 y 9 respectivamente, con edad media de 37,4 años. El 93 por ciento y el 80 por ciento se presentaron como cuadro apendicular agudo respectivamente. La histopatología evidenció Tumor Neuroendocrino (MET) en 87 por ciento y 70 por ciento respectivamente, seguido por Linfoma no Hodgkin y adenocarcinoma. Se realizó estudio de extensión en 4 y 5 pacientes respectivamente, cuatro pacientes fallecieron en el período de seguimiento, uno a causa de diseminación. Discusión: En ambos centros la presentación clínica fue similar, el NET fue el más frecuente. La incidencia fue significativamente mayor en HRA, p < 0,05. El estudio histopatológico rutinario es fundamental para el diagnóstico y tratamiento.

Single incision laparoscopic right hemicolectomy: different approaches / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Single incision laparoscopic colectomy has been performed in recent years, and has been shown to be feasible and safe. This study was to assess the feasibility of single incision laparoscopic right hemicolectomy and to compare the differences in different approaches.</p><p><b>METHODS</b>This retrospective study included eighteen patients with carcinoma of caecum and ascending colon, undergoing single incision laparoscopic right hemicolectomy. This study also compared single incision laparoscopic right hemicolectomy using different approaches: (1) single incision multiport, (2) single access port and (3) glove port.</p><p><b>RESULTS</b>There was no statistical difference in surgical outcomes. Concerning the surgeon's satisfaction toward three methods, overcrowding and durability were similar but the single incision multiport was associated with the highest gas-leak and the "glove" port was associated with poor durability. However, the method of single incision multiport has the lowest average cost of the special trocar or port in each operation. The operative time and blood loss of the operations in this study were comparable to previous publications.</p><p><b>CONCLUSION</b>There was no significant difference between different approaches of single incision laparoscopic right hemicolectomy for colonic cancer in right side colon.</p>

Adenocarcinoma Arising in a Duplication of the Cecum

Intestinal duplications are rare developmental abnormalities that may occur anywhere in the gastrointestinal tract. The possibility of a malignant change occurring in these duplications is very low. We present a case of adenocarcinoma arising in a duplication of the cecum. A 41-year-old male patient was admitted because of a palpable abdominal mass. Abdominal computed tomography revealed a 6-cm, peripheral wall-enhanced, round, cystic mass in the cecal area. Excision of the mesenteric mass and a right hemicolectomy was performed. Upon histologic examination, the patient was diagnosed with adenocarcinoma arising in a duplication of the cecum.

Linfoma de Celulas Grandes B Difuso Gastrointestinal del Anciano Asociado al Virus Epstein Barr: Reporte de Cinco Casos y Revision de la Literatura / Gastrointestinal Epstein Barr Virus positive diffuse large B cell lymphoma in elderly: report of five cases and review of literatura

El Linfoma de Células Grandes B difuso del anciano asociado al Epstein Barr es una nueva entidad incluida provisionalmente en la más reciente clasificación de neoplasias linfoides de la WHO. Usualmente afecta ancianos y tiene pobre sobrevida. El objetivo de este reporte fue evaluar las característica clínicas, endoscópicas y sobrevida de cinco pacientes portadores de esta entidad y compromiso gastrointestinal. Tres casos tuvieron infiltración gástrica y dos casos tuvieron compromiso del ileón y el ciego.

EBV-positive diffuse large B-cell lymphoma (DLBCL) in elderly is a new entity included provisionally in the most recent WHO Classification of lymphoid neoplasms. It usually affects elderly patients and has a poor survival. The goal of this report was to evaluate clinical, endoscopic characteristics and survival of five patients with this entity and gastrointestinal afectation. From five cases, three cases had gastric infiltration, one ileon and one in cecum.

Hernia de Spiegel vs. neoplasia de colon: a propósito de un caso / Spigelian hernia vs. colonic neoplasias: apropos of a case

Las hernias de Spiegel son una entidad rara y ocurren a través de defectos de la fascia homónima. El diagnóstico es difícil; puede ser auxiliado por tomografía axial computarizada y ultrasonido. Se reporta el caso de una paciente de 46 años de edad, referida al servicio de Imágenes del Hospital Universitario Clínico-Quirúrgico Comandante Faustino Pérez, de Matanzas, con historia de dolor abdominal inespecífico desde hace cuatro años; ahora con masa abdominal palpable en cuadrante inferior derecho e imagen sugestiva de neoplasia de ciego en examen de colon por enema realizado en el hospital de referencia. Su diagnóstico puede ser virtualmente imposible a menos que la entidad sea previamente considerada, ahí radica la importancia del reporte

Spigelian hernias are a rare entity and occur through defects in the homonym fascia. The diagnosis is difficult; it may be helped by on-line axial tomography and ultrasound. We report the case of a 46- years-old patient remitted to the Imaging Service of the Clinical-Surgical University Hospital Comandante Faustino Pérez, of Matanzas, with a history of unspecific abdominal pain for four years, now with a palpable abdominal mass in the right lower quadrant and image suggesting cecum neoplasias in colon examination by enema made in the before mentioned hospital; their diagnosis may be virtually impossible unless the entity is previously considered; that is where the importance of the report resides

Tumor carcinoide del apéndice cecal / Carcinoid tumor of the appendix: case presentation

Los tumores carcinoides del tracto gastrointestinal se originan de las células endocrinas situadas en las criptas de la mucosa del tubo digestivo, generalmente llamadas células de Kulchitsky. El apéndice es la localización más frecuente de los tumores carcinoides intestinales, seguido del intestino delgado, sobre todo el íleon, el recto, el estómago y el colon. El pico de incidencia se presenta en la tercera y cuarta décadas de la vida. Estos tumores se encuentran, aproximadamente, en una de cada 300 apendicectomías de rutina, su detección preoperatoria es rara y es el tumor más común del apéndice; casi siempre se descubre al estudiar una apendicitis. Generalmente, están localizados en la punta del apéndice. Presentamos un caso de tumor carcinoide apendicular. El paciente era un hombre de 30 años de edad, al cual se le practicó una apendicectomía, al parecer, por un cuadro agudo de apendicitis. El resultado anatomopatológico confirmó un tumor neuroendocrino bien diferenciado de 1,2 cm de diámetro mayor con compromiso de toda la pared, incluida focalmente la serosa y el mesoapéndice, con presencia de invasión vascular tumoral, la base del apéndice libre de tumor, y una apendicitis aguda perforada. Se discute la conducta frente al hallazgo de dicho tumor.

The carcinoid tumors of the gastrointestinal tract originate in endocrine cells located in the crypts of the mucosa of the digestive tract, usually called Kulchitsky cells. The appendix is the most common site for the development of intestinal carcinoid tumors, which are usually located at the tip of the appendix; they also occur in the small bowel, especially the ileum, rectum, stomach and colon. The peak incidence is in the third and fourth decades of life. These tumors are found in about one of every 300 appendectomies, routine preoperative detection is rare, and they represent the most common tumor of the appendix. Almost always they are found as appendicitis. We report a case of appendiceal carcinoid tumor. The patient is a male aged 30, which underwent appendectomy because of appendicitis. The pathology study confirmed a well differentiated neuroendocrine tumor of 1.2 cm in diameter with involvement of the entire wall including the serosa and focally the mesoappendix, tumor vascular invasion, base of the appendix free of tumor, perforated appendicitis. Behavior will be discussed against the findings of this tumor.

Cecal carcinoma presenting with adult intussusception

Adult intussusception is an uncommon cause of bowel obstruction. It usually presents with longstanding, intermittent and non-specific symptoms with subsequent delay in diagnosis and management. Diagnosis is often made at emergency laparotomy and an underlying lesion is found in most cases. With more frequent use of computed tomography in the evaluation of patients with abdominal pain, the condition can now be diagnosed more reliably at an earlier stage and this is of importance as 50% of adult intussusceptions are due to malignancy. We report a case of a 55-year-old lady who presented to the emergency department with ileocolic intussusception which was diagnosed on CT scan and necessitated an emergency right hemicolectomy. The leading point was a small cecal cancer reflecting the importance of early intervention and resection in cases of adult intussusception. This case also highlights the fact that early cecal cancer may first present and declare itself as intussusceptions

Carcinoma caecum; metastasis to ileostomy from mucinous adenocarcinoma

Most of patients with colorectal carcinoma end up with colostomies and ileostomies. Different complications are described pertinent to ileostomies. We are presenting a very rare presentation of ileostomy, the metastasis from mucinous adenocarcinoma of caecum, without ileostomy dysfunction, local bleeding as presenting complaint along with a ileostomy growth

Abdominal tuberculosis may masquerade many diseases

Intestinal tuberculosis needs to be considered in the differential diagnosis when patients with intestinal pathology are encountered. Tuberculosis can mimic other disease entities like, ischemic enteritis, inflammatory bowel diseases, malignancies, intussusception etc., clinically as well as morphologically in resected intestinal specimens. We aimed to study the various clinical presentations leading to intestinal resection, with identification of different etiological factors by histopathological examination; and to illustrate, discuss and describe the various histopathological features of the lesions in these resected intestinal specimens with clinicopathological correlation. We studied 100 cases of resected intestinal specimens received during September 2002 to December 2003. We totally encountered 22 request forms with clinical suspicion of ileoceocal tuberculosis. Abdominal tenderness and mass in ileoceocal region were noted in all cases. In many instances, the cases were operated for acute/subacute intestinal obstruction. Clinical and intra-operative diagnoses of tubercular enteritis, in many instances, were finally diagnosed histopathologically as ischemic enteritis [nine cases], chronic nonspecific enteritis [four cases], adenocarcinoma of the caecum, Crohn's disease, intussusception [each one case], and correctly as intestinal tuberculosis in only six cases. Tuberculosis can mimic various disease entities, clinically and sometimes morphologically. Vice versa is also true. An increased awareness of intestinal tuberculosis coupled with varied clinical presentations, nonspecific signs and symptoms, difficulties in diagnostic methods and need of early and specific treatment should improve the outcome for patients with this disease

Cistoadenoma mucinoso de apéndice: informe de un caso / Mucinous cystadenoma of the appendix: case report

Introducción: La patología apendicular representa más de 50% de la actividad quirúrgica general, y dentro de ésta hay que considerar las raras, entre las que se incluyen los mucoceles, cuya incidencia es mayor en mujeres (4/1) y en pacientes con edad superior a 50 años. El objetivo de este trabajo es informar un caso de cistoadenoma mucinoso de apéndice. Caso clínico: Hombre de 34 años de edad con diagnóstico a los nueve años de edad de artritis reumatoide juvenil; con prótesis bilateral de cadera a los 22 años. Presenta amiloidosis renal desde 1998 y se encuentra en tratamiento con esteroides hasta el momento de este informe. El cuadro clínico se inició un año atrás, cuando en una tomografía axial computarizada de abdomen de control se encontró tumoración en la fosa iliaca derecha, confirmada por colonoscopia en ciego. Por diagnóstico presuntivo de lipoma fue programado para cirugía; en el transoperatorio se encontró gran tumoración de pronóstico reservado, por lo que se decidió hemicolectomía derecha. El informe de patología de la pieza quirúrgica fue cistoadenoma mucinoso. Conclusiones: La sintomatología del cistoadenoma es inespecífica. Los métodos de diagnóstico incluyen rayos X, ultrasonido, tomografía axial computarizada y colonoscopia. El cistoadenoma es la forma más común de los mucoceles apendiculares y el protocolo de diagnóstico es igual que para patología de apéndice cecal. El tratamiento de elección es la cirugía y depende del tamaño del mucocele. El pronóstico es bueno con el tratamiento adecuado.

BACKGROUND: Pathology of the appendix represents >50% of surgical activity. It is necessary to consider rare pathologies such as mucoceles. These have a high frequency in females with a F/M ratio of 4:1, as well as in patients >50 years of age. The objective of this study is to report on a case of mucinous cystadenoma of the appendix. CLINICAL CASE: We present the case of a 34-year-old male with a history of juvenile rheumatoid arthritis diagnosed at 9 years of age. At 22 years of age, the patient underwent bilateral hip arthroplasty. Since 1998, the patient has presented with renal amyloidosis and has been under steroid treatment to date. The current problem evolved 1 year ago during control studies for his disease. Computed tomography (CT) of the abdomen was done, demonstrating a tumor in the right iliac fossa. Colonoscopy confirmed a tumor with smooth edges located in the cecum. Surgery was recommended with a diagnosis of lipoma of the cecum. During surgery, a large tumor was found, indicating a poor prognosis. Right hemicolectomy was done. Surgical specimen was sent to pathology with a report of mucinous cystadenoma. CONCLUSIONS: The group of symptoms of cystadenoma is nonspecific. Diagnostic methods include X-rays, ultrasound, CT and colonoscopy. Mucinous cystadenoma is the most common form of mucocele of the appendix. Diagnostic protocols are the same for benign appendix pathology. Treatment is surgical and type of surgery depends on the size of the mucocele. Mucoceles of the appendix are pathologies with a favorable prognosis when appropriate treatment is done.

Carcinoma escamoso: rara variedad de neoplasia colónica / Primary squamous cell carcinoma: a rare variety of colon cancer

Introducción: El cáncer colorrectal es la neoplasia más frecuente del tubo digestivo y la segunda en nuestro país en incidencia y mortalidad. El carcinoma de células escamosas de colon y recto es raro. La mayoría de los datos sobre ellos provienen de comunicaciones individuales y no se conoce mucho sobre su etiología, patogenia y pronóstico. Se presenta un caso de carcinoma escamoso primario localizado en ciego, con revisión de la literatura. Lugar de aplicación: Hospital de Alta Complejidad Presidente Juan Domingo Perón, Formosa, Argentina. Diseño: Presentación de caso clínico y revisión de la literatura. Pacientes y Métodos: Mujer de 67 años. Consulta en mayo de 2006 por anemia crónica y alteración del estado general. Presenta como antecedente anexohisterectomía por carcinoma epidermoide de cuello uterino con radioterapia adyuvante 10 años atrás. Al examen físico se palpa tumoración en fosa ilíaca derecha. La videocolonoscopía constata formación tumoral en ciego. Se toman biopsias, cuyo informe anatomopatológico revela carcinoma escamoso. Se realiza hemicolectomía derecha videolaparoscópica. Evoluciona sin complicaciones. Resultados: El protocolo de anatomía patológica informa: "Carcinoma escamoso moderadamente diferenciado infiltrante de ciego con metástasis en 12 de 14 ganglios resecados, con embolizaciones vasculares; estadificación patológica pT3-pN2-pMO / Dukes C2". Completó tratamiento adyuvante con 5 Fluorouracilo, Leucovorina y Oxaliplatino. Óbito por progresión de enfermedad a los 25 meses de seguimiento. Conclusiones: El carcinoma escamoso primario de colon y recto es una neoplasia sumamente infrecuente. La resección quirúrgica se presenta como la opción terapéutica más acertada. La efectividad de la adyuvancia no está comprobada. Su pronóstico parece ser peor que el de los adenocarcinomas para el mismo estadío.

Background: The colorectal cancer is more frequent neoplasia of the digestive tract and it is the second in our country in incidence and mortality. The squamous cell carcinoma of the colon and rectum is rare. Most of the data about them come from individual communications and is not know about its etiology, pathogenesis and prognosis. A primary squamous cell carcinoma of the colon case is submitted, it is located in the cecum with revision of the literature. Place of aplication: Hospital de Alta Complejidad Presidente Juan Domingo Perón, Formosa, Argentina. Design: Report of a case and revision of literature. Patients and Methods: Female patient of 67 years old. She consults in May of 2006 by chronic anemia and malaise. History of hysterectomy with bilateral salpingo-oophorectomy and adjuvant radiotherapy in epidermoid carcinoma of uterine cervix ten years ago. In the physical examination is felt a tumor in right iliac fosse. Videocolonoscopy shows tumor mass in cecum. Biopsies are taken, whose anatomopathologic report reveals squamous cell carcinoma. Results: A laparoscopic right colectomy is carried out. Patient evolves without complications. The protocol of anatomopathology report: "Moderately differenciated squamous cell carcinoma of the cecum with metastasis in 12 of 14 resects nodes with vascular embolizations; pathological staging pT3-pN2-pMO / Dukes C2". She completes adyuvant treatment with 5 Fluorouracil, Leucovorin and Oxaliplatin. She died at 25 months of follow up. Conclusions: Primary Squamous cell carcinoma of the colon and rectum is a rare malignancy. Surgical resection is presented like the wisest therapeutic option. Effectiveness of adjuvancy is not proven. Its prognostic seems to be worst than adenocarcinomas for the same phase.

Invaginación ileocecal como forma de presentación de linfoma no Hodgkin en un paciente con SIDA / Ileocolic intussusception due to a large B cell lymphoma in a patient with AIDS

La invaginación intestinal es poco frecuente en el adulto. Aquí se describe el caso de un paciente adulto con SIDA que desarrolló una invaginación ileocólica secundaria a un linfoma de células B localizado en el ciego. Los hallazgos quirúrgicos fueron: íleon libre de tumor, invaginado en el ciego infiltrado por la neoplasia. Se realizó la resección del hemicolon derecho debido a la tumoración localizada en el ciego, causante de la invaginación. Se revisó la literatura inglesa y española sobre este tema.

Adult intussusception is rare. Here, we describe a case of an AIDS adult patient who developed an ileocolic intussusception secondary to a large B cell lymphoma of the cecum. Surgical findings included the ileon free of the tumor and invaginated within the cecum with infiltrating neoplasm. Surgical treatment included the resection of the right hemicolon because of the tumor, located in the cecum, causing intussusception. The english and spanish literature is reviewed.

Cecal Cancer with Xanthogranulomatous Inflammation

Xanthogranulomatous inflammation is a chronic inflammatory condition characterized by aggregation of lipid-laden foamy macrophages (xanthoma cells). This disease entity is well- recognized in the kidney and gallbladder. However, involvement of the colon is extremely rare. Radiologically, xanthogranulomatous inflammation could be misinterpreted as a locally invasive cancerous lesion. Indeed, coexisting malignancy has been reported in xanthogranulomatous inflammation. In this case report, a woman complained of fever and right lower quadrant abdominal pain for a period of 5 days. A huge mass lesion with severe pericolic infiltration was found on abdominal CT scan. Right hemicolectomy was performed along with removal of the adjacent soft tissue and right ovary and fallopian tube. Pathology examination demonstrated xanthogranulomatous inflammation coexisting with cecal cancer (T3N0M0).

Synchronous carcinoid tumour of the small intestine and appendix in the same patient / Tumor carcinoide sincrónico del intestino delgado y el apéndice en el mismo paciente

Carcinoid tumours have been reported in a wide range of organs but most frequently involve the gastrointestinal tract. Many of these carcinoid tumours are associated with metachronous and synchronous lesions of another histological type. Primary carcinoid tumours of the different organ in the same patient is rare. In this paper, the authors present a case with synchronous carcinoid tumour of the small intestine and appendix in the same patient.

Se han reportado tumores carcinoides en una amplia variedad de órganos, pero el lugar de detección más frecuente ha sido el tracto gastrointestinal. Muchos de estos tumores carcinoides se hallan asociados con lesiones metacrónicas y sincrónicas de otro tipo histológico. La presencia de tumores carcinoides primarios de un órgano diferente en el mismo paciente es rara. En este trabajo, los autores presentan un caso con tumores carcinoides sincrónicos del intestino delgado y el apéndice en el mismo paciente.
