Tumores anexiales incidentales en cirugía abdominal / Incidental adnexal tumors in abdominal surgery

La posibilidad de encontrar una neoplasia benigna o maligna del ovario, de forma inesperada durante una intervención quirúrgica abdominal, es una realidad para todos los especialistas en cirugía. Si bien en muchos casos se tratará de una lesión benigna, el riesgo de cáncer no debe subestimarse, ya que, por ejemplo, la ruptura intraoperatoria de una lesión quística maligna puede reestadificar a una paciente con cáncer de ovario del estadio IA al IC, con todas las consecuencias que esto implica, como la necesidad de requerir quimioterapia adyuvante y tener un peor pronóstico. Por otro lado, en mujeres premenopáusicas debe discutirse con la familia o la paciente (idealmente) el riesgo e implicaciones de la ooforectomía uni o bilateral, incluso si esto amerita dejar el quirófano para obtener el consentimiento, o posponer el procedimiento definitivo para un segundo tiempo. La consulta intraoperatoria a un ginecólogo, siempre que sea posible, se debe llevar a cabo con el fin de respaldar la conducta adoptada. Conocer el manejo adecuado de las masas anexiales encontradas de forma incidental durante una cirugía abdominal, es una prioridad para todos los cirujanos generales.

The possibility of finding a benign or malignant neoplasm of the ovary unexpectedly during abdominal surgery is a reality for all specialists in surgery. Although in many cases it will be a benign lesion, the risk of cancer should not be underestimated, since, for example, the intraoperative rupture of a malignant cystic lesion may well re-stage a patient with ovarian cancer from stage IA to IC, with the consequences that this implies, such as the need for adjuvant chemotherapy and a worse prognosis. On the other hand, in premenopausal women, the risk and implications of unilateral or bilateral oophorectomy should be discussed with the family or the patient (ideally), even if this implies leaving the operating room to obtain consent, or postponing the definitive procedure for a second time. Intraoperative consultation with a gynecologist, whenever possible, should be carried out in order to support the adopted behavior. Knowing the proper management of adnexal masses found incidentally during abdominal surgery is a priority for all general surgeons.

Analysis of prognosis factors and follow-up strategy of ovary metastasis derived from gastric and colorectal cancer / 国际外科学杂志

Objective:To analyze the prognostic factors of Krukenberg tumors derived from the gastric cancer and colorectal cancer, so as to guide comprehensive treatment; looking for objective and sensitive indicators of ovarian metastasis during the follow-up after the surgery for gastric and colorectal cancer, which provides a basis for early diagnosis.Methods:Retrospectively analyzed the clinical data of 75 patients diagnosed with Krukenberg tumor admitted to Beijing Friendship Hospital, Capital Medical University from June 2007 to February 2020. Log-rank method and COX regression analysis were used to find independent prognostic factors. Wilcoxon rank sum test was used to compare the dynamic changes of ovarian imaging and tumor markers and to find the more sensitive indicators in the follow-up of patients with metachronous metastasis.Results:In the 75 cases, the univariate analysis suggested that CA19-9≥123.5 U/mL ( P=0.001), CA12-5≥37.9 U/mL ( P=0.018), Krukenberg tumor of stomach origin ( P=0.037), extra-ovary metastasis ( P=0.014), and without cytoreductive surgery (CRS) ( P<0.001)were poor prognostic factors. Among them, cytoreductive surgery could significantly improve the prognosis, even if with visible residual lesions, the overall survival was still significantly longer than those who have not undergone cytoreductive surgery ( P=0.004). Multivariate analysis results showed that CA19-9 and cytoreductive surgery ( P=0.001) were independent prognostic factors for patients with Krukenberg tumor; during the postoperative follow-up, ultrasound and CT imaging changes were more sensitive to ovarian metastasis ( P=0.006). Conclusions:CRS can prolong significantly the overall survival (OS) of patients with krukenberg tumor. Patients with simultaneous metastases should not give up the opportunity for surgery, and patients with metachronous metastases should also receive ovary resection procedure, even if with visible residual lesions, the patients can still benefit from the procedure. In the follow-up for gastric and colorectal cancer, attention should be paid to the ovarian ultrasound and CT imaging changes to facilitate early detection of ovarian metastases.

A challenge for colorectal surgeons: pathogenesis, progression and management of the secondary tumors of the ovary / 中华胃肠外科杂志

A common clinical problem encountered by colorectal surgeons is the secondary tumors of the ovary (STO), particularly in young female patients. Most STO are from the digestive tract, and the known possible metastatic mechanisms include lymphatic, hematogenous, and intraperitoneal spreading. The molecular and histopathological characteristics of STO from different sites are diverse. It is particularly important to correctly identify the origin and feature of STO, which should be clarified by combining medical history, histopathology, immunohistochemistry, molecular biology, imaging and other means. The prognosis of patients with STO is poor in general. Comprehensive therapies based on surgical resection can benefit some patients. There is no specific treatment for STO at present, but not giving up easily on these patients is the right choice that every surgeon should understand.

Ectopic Cushing’s Syndrome secondary to Recurrent Thymic Neuroendocrine Carcinoma with Bilateral Ovarian Metastases: A case report / Journal of the ASEAN Federation of Endocrine Societies

@#Cushing’s syndrome due to ectopic adrenocorticotrophic hormone (ACTH) secretion is uncommon, accounting for 9 to 18% of cases; approximately 10% of ACTH producing tumours are caused by thymic carcinomas.1 We describe a young lady who presented with Cushing’s syndrome secondary to a primary neuroendocrine tumour (NET) arising from the thymus. She had surgical resection of her primary tumour with remission of her Cushing’s syndrome however subsequently went on to have locoregional recurrence followed by distant metastases to her bilateral ovaries. She underwent 6 surgeries including bilateral adrenalectomy and had 3 cycles of chemotherapy over the course of the 8 years since her diagnosis. Due to the rarity and highly aggressive nature of this disease, we highlight the need for a multidisciplinary team approach and use of multiple modalities in the management of our patient. Timely use of bilateral adrenalectomy particularly in young patients is important to prevent further complications and facilitate other treatment modalities.

Exceptionally Rare Krukenberg Tumour in a Patient With Dextrocardia and Situs Inversus Totalis

@#Krukenberg tumour is a rare clinical entity and accounts for about 1-2% of all ovarian tumours. It is a metastatic ovarian tumour in which accurate diagnosis requires proper endoscopic evaluation and histopathological confirmation to exclude primary ovarian tumours. Dextrocardia with situs inversus totalis is another unusual clinical entity, with an incidence of 1 in 10,000 of the general population. Many patients with this unusual condition are unaware of their structural abnormality and mostly are diagnosed incidentally when they present with other medical conditions. Herein, we report a case of 47 years old woman who presented with bilateral ovarian tumour and incidental diagnosis of Dextrocardia with situs inversus totalis. She underwent surgery and histopathological examination confirms Krukenberg tumour. Both conditions existing together, an exceptionally rare clinical entity.

Krukenberg Tumour Arising from Gall Bladder- A Rare Presentation

Introduction: Krukenberg tumours are rare, usually bilateral,metastatic ovarian tumours presenting in perimenopausalage women. It usually arises from the GIT (stomach/colon),however it may arise from other rare sites like breast, appendix,biliary tract and gall bladder. Imaging plays a definite role inthe diagnosis and management of such cases.Case report: In this paper, we report two interesting cases ofbilateral ovarian masses where the primary site of malignancywas GB. The first case showed synchronous metastases to theovary while the second one showed metachronous metastasesto the ovary.Conclusion: This report highlights the importance of keepingin mind the rare sites of primary tumour while dealing withbilateral ovarian masses.

A rare case of steroid cell tumor of ovary: case report

Steroid cell tumors of the ovary account for less than 0.1% of all ovarian tumors. These tumors may present at any age with presentations related to the hormonal activity and virilizing properties of tumor. A 61-year-old postmenopausal women presented with complaints of postmenopausal bleeding for 15 days. Parity score of P3L3, not tubectomised. Menopaused 16 years back. History of weight loss noted. She is a known case of diabetes mellitus for 6 years not on any treatment and a known case of depressive disorder for 35 years on treatment on trihexphenidyl lurasidone. Had undergone sigmoid colon polyp removal in June 2018. On examination, P/A- mild gaseous distension (+). P/S- cervix flushed with vagina, pulled up cervix. P/V- uterus size and position couldn’t be made out, anterior fornix fullness (+). Ultrasonography showed bulky uterus with fibroid 4x4cm, endometrial thickness- 9 mm? Krukenberg tumor and posterior mediastinal lymph nodes. Patient underwent Total abdominal hysterectomy with bilateral salpingo-oophorectomy with frozen section on 01/07/19. Frozen section: 1. Ovaries: right ovary - fibrothecoma, left ovary- simple cyst. 2. Uterus- endometrial hyperplasia with atypia. 3. Myometrium- leiomyoma and adenomyosis. Postoperative period was uneventful. On microscopic examination, impression: right ovary- steroid cell tumor, uterus-endometrial hyperplasia with cytological atypia. Ovarian steroid cell tumors are grouped under sex chord stromal tumors and are usually benign, unilateral and characterized by a steroid cell proliferation. Steroid cell tumors are associated with androgenic changes with variable frequency, ranging from 12% to over 50% respectively. The primary treatment is surgical extirpation of the primary lesion and there are no reports of effective radiation or chemotherapy. In a young patient with stage IA disease, a unilateral salpingo oophorectomy is adequate.

Diagnosis and treatment strategy of gastric cancer with ovarian metastasis / 中华肿瘤杂志

Ovary is one of the common metastatic sites of gastric cancer. In the female patients, ovarian relapse is one of the most important causes of treatment failure for gastric cancer. The most likely mechanism of Krukenberg tumor development is via retrograde lymphatic spreading from gastric cancer. However, neither optimal treatment strategy nor standard treatment guideline for Krukenberg tumor from gastric cancer has been clearly established.The diagnostic key points consist of the previous or concomitant history of gastric cancer and the detection of ovarian solid tumors.The therapeutic regimens mainly include the metastasectomy, chemotherapy, radiotherapy and comprehensive treatment. Surgical resection of metastatic tumor combined with adjuvant chemotherapy can improve the prognosis and survival.

Peritonectomía con quimioterapia intraperitoneal hipertérmica en el tratamiento del tumor de Krukenberg. A propósito de un caso clínico / Peritonectomy with hyperthermic intraperitoneal chemotherapy in the treatment of Krukenberg tumor. A clinical case

Resumen ANTECEDENTES: el tumor de Krukenberg es una neoplasia caracterizada por metástasis ováricas de origen digestivo. El diagnóstico se establece en estadios avanzados de la enfermedad, mediante pruebas de imagen y determinación de marcadores inmunorreactivos relacionados con enfermedades del aparato digestivo. En la mayoría de los casos existe afectación bilateral en ambos anejos. OBJETIVO: reportar el caso de una paciente con tumor de Krukenberg. CASO CLÍNICO: paciente de 41 años de edad, intervenida de cáncer de mama hacía 10 años como único antecedente ginecológico de interés. Se diagnosticó con metástasis ovárica de adenocarcinoma gástrico primario, tratada con cirugía radical y quimioterapia hipertérmica intraperitoneal, con supervivencia de casi dos años entre el diagnóstico del tumor y su fallecimiento. CONCLUSIÓN: el tratamiento de estas neoplasias es muy agresivo, incluye cirugías radicales (peritonectomía) asociadas con quimioterapia para la carcinomatosis concomitante y técnicas hipertérmicas intraperitoneales. La supervivencia varía en función de las series reportadas y, en términos generales, se considera una neoplasia de muy mal pronóstico

Abstract BACKGROUND: These tumors are defined as metastatic ovarian adenocarcinomas of usually digestive origin. The few symptoms usually occurs when the disease is in advanced stages and, in most cases, with bilateral extension to both annexes. Krukenberg tumors frequently appear in young patients. Diagnosis is based on imaging tests and on the sensitivity of these tumors to specific immunoreactive markers, especially to those related to diseases of the digestive tract. OBJECTIVE: report the case of a patient with Krukenberg tumor. CLINICAL CASE: present the case of a patient who underwent breast cancer surgery 10 years ago as the only gynecological history of interest, who was diagnosed with ovarian metastases of primary gastric adenocarcinoma, treated with radical surgery plus intraperitoneal hyperthermic chemotherapy, and with survival of almost two years between tumor diagnosis and patient exitus. CONCLUSION: These therapies include radical surgeries such as peritonectomy, chemotherapy treatments aimed at treating associated carcinomatosis, and hyperthermic intraperitoneal techniques. Survival can vary depending on the series, and it is generally considered a disease of very poor prognosis.

Tumor de Krukenberg secundario a carcinoma de colon durante el embarazo / Krukenberg tumor secondary to carcinoma of the colon during pregnancy

El tumor de Krukenberg (TK) es un tumor metastásico en el ovario, y el carcinoma primario más frecuente es el de origen gástrico. Su incidencia es muy baja en la población general, y excepcional su asociación al embarazo. Se presenta el caso de una paciente de 17 años con diagnóstico de tumor de Krukenberg en las 20 semanas de gestación, como tumor primario se encontró un adenocarcinoma de colon.

Krukenberg tumor (KT) is a metastatic tumor in the ovary, and the most common primary carcinoma is the gastric origin. Its incidence is very low in general population, and its association with pregnancy is exceptional. A 17 year-old patient is presented here with diagnosis of Krukenbergen tumor at the 20th weeks of gestation, as primary tumor a colon adenocarcinoma was found.

Bilateral Krukenberg Tumor.

Adrenal Myelolipoma is a rare tumor that is benign in nature and unilateral. It is usually asymptomatic with just a few millimeters in size but they can grow over 30 cms becoming a life threat to the patient. This tumor is generally considered as a type of hormonally inactive neoplasm which is composed of variable amounts of mature adipose tissue and normal hematopoeitic elements. These may not account for extramedullary sites of haemotopoiesis and are not associated with any specific hematologic disorder. Rarely, Adrenal Myelolipomas occur in association with Adrenocortical Adenoma or Adrenocortical Carcinoma. We report a case of Adrenocotical Adenoma with Myelolipoma in a 35 year old female who presented with pain in the right upper abdomen. The radiological appearance resembled adrenocortical carcinoma. This case emphasize the importance of this combination as a pitfall in the correct diagnosis and management of patient with Adrenal mass.

Tumor de Krukenberg del ovario asociado a teratoma maduro / Krukenberg tumor of the ovary associated with mature teratoma

Se reporta un caso excepcional de tumor de Krukenberg ovárico bilateral asociado a teratoma maduro encontrado en una mujer de 54 años. La ecografía mostró al lado derecho tumor ovárico sólido de 55 mm y al lado izquierdo tumor quístico de 125 mm. Se realizó histerectomía total, salpingooforectomía bilateral, resección del epiplón mayor y muestras peritoneales. Al tercer día postcirugía, la paciente presentó signos de tromboembolismo pulmonar masivo y aunque recibió terapia anticoagulante falleció al quinto día postoperatorio. El estudio histológico mostró infiltración masiva de carcinoma de células en anillo positivas para citoqueratina en ambos ovarios. El ovario derecho mostró la forma sólida clásica del tumor de Krukenberg mientras que el ovario izquierdo correspondió a un quiste dermoide con infiltración tumoral de carcinoma de células en anillo en la pared.

An exceptional case of bilateral Krukenberg tumor of the ovary associated with mature teratoma presented in a 54 years old patient is reported. The ultrasound showed a 55 mm solid right ovarian tumor and a 125 mm left cystic ovarian tumor. Hysterectomy and bilateral salpingoophorectomy was performed including omental resection and peritoneal biopsies. Massive pulmonary embolism was detected in the third day after the surgery. Even anticoagulant therapy was established the patient died in the fifth postoperative day. The histological study revealed massive infiltration of signet ring cell carcinoma with positive expression for cytokeratin in both ovaries. The right ovary showed the classical solid form of the tumor. The left ovary was a dermoid cyst with signet ring cell carcinoma infiltrating the cystic wall.

Krukenberg tumors of gastric origin versus colorectal origin

OBJECTIVE: The aim of this study is to compare the each clinical manifestation related with its mean survival time of Krukenberg tumors (KTs) of gastric origin versus with that of colorectal origin. METHODS: A total of 156 consecutive patients diagnosed with KTs of the ovary who underwent surgical treatment at a single institution between 2001 and 2010 were retrospectively evaluated. Each clinical manifestation related with its mean survival time compared two different groups. Survival analyses and comparisons were performed using the Kaplan-Meier method. RESULTS: Among the 156 patients with KT, 111 patients with KTs of gastric origin and 45 patients with KTs of colorectal origin were identified. For all patients with KTs, median survival time was 22.7 months. Each mean survival time among all patients with KTs of gastric origin and colorectal origin was 19.2 months and 27.3 months. The results showed that mean survival time of postmenopausal patients was 19.0 months compared with 32.5 months for premenopausal patients (P=0.015). Among all patients, mean survival time of those with metachronous cancer was longer than those with synchronous cancer (P=0.001). In all cases, especially when only one ovary was invaded, the mean survival time was relatively higher (P=0.001). CONCLUSION: Patients with KTs of colorectal origin had a better prognosis than those of gastric origin. In all cases of KT, the mean survival time was significantly longer in postmenoposal patients, metachronous disease and unilateral ovarian involvement. Notably, synchronous, ascites positive, and ovary only metastasis showed more longer mean survival time in the KTs of colorectal origin than KTs of gastric origin.

Comparison of Surgery Plus Chemotherapy and Palliative Chemotherapy Alone for Advanced Gastric Cancer with Krukenberg Tumor / Journal of the Korean Cancer Association, 대한암학회지

PURPOSE: This study was conducted to validate the survival benefit of metastasectomy plus chemotherapy over chemotherapy alone for treatment of Krukenberg tumors from gastric cancer and to identify prognostic factors for survival. MATERIALS AND METHODS: Clinical data from 216 patients with Krukenberg tumors from gastric cancer were collected. Patients were divided into two arms according to treatment modality: arm A, metastasectomy plus chemotherapy and arm B, chemotherapy alone. RESULTS: Overall survival (OS) was significantly increased in arm A relative to arm B for patients initially diagnosed with stage IV gastric cancer (18.0 months vs. 8.0 months; p < 0.001) and those with recurrent Krukenberg tumors (19.0 months vs. 9.0 months; p=0.002), respectively. Metastasectomy (hazard ratio [HR], 0.458; 95% confidence interval [CI], 0.287 to 0.732; p=0.001), signet-ring cell pathology (HR, 1.583; 95% CI, 1.057 to 2.371; p=0.026), and peritoneal carcinomatosis (HR, 3.081; 95% CI, 1.610 to 5.895; p=0.001) were significant prognostic factors for survival. CONCLUSION: Metastasectomy plus chemotherapy offers superior OS when compared to palliative chemotherapy alone in gastric cancer with Krukenberg tumor. Prolonged survival applies to all patients, regardless of gastric cancer stage. Metastasectomy, signet-ring cell pathology, and peritoneal carcinomatosis were prognostic factors for survival. Future prospective randomized trials are needed to confirm the optimal treatment strategy for Krukenberg tumors from gastric cancer.

Tumor de Krukenberg / Krukenberg tumor

Introducción: el Krukenberg es un tumor metastático y representa del 1 por ciento al 2 por ciento de los tumores de ovario. El estómago es en el 70 por ciento de los casos la localización primaria más frecuente, seguidos por colon, apéndice y mama. El pronóstico es desfavorable y la evolución es rápida. Objetivo: describir un caso clínico de una paciente con tumor de Krukenberg. Presentación del caso: mujer de 53 años que consulta por sangramiento posmenopáusico a tipo manchas y dolor bajo vientre. Antecedentes personales de carcinoma gástrico, litiasis vesicular, nódulo de mama e hipertensión arterial. Se realizó estudio sonográfico ginecológico con marcadores para tumor de ovario positivos. Marcadores tumorales negativos. Resultados: hallazgo transoperatorio: se observó útero miomatoso y ambos ovarios multiloculados, superficie de revestimiento lisa de contenido mucinoso, con áreas sólidas de coloración heterogénea y consistencia renitente. Se realizó histerectomía con doble anexectomía. Conclusiones: el Krukenberg, tumor metastásico de ovario, es una entidad rara con mal pronóstico luego de su diagnóstico. Aún así la resección de dicha lesión metastásica es la primera recomendación la cual parece mejorar la sobrevida, seguida de terapia sistémica paliativa.

Introduction: Krukenberg tumor is metastatic and it accounts for 1 percent to 2 percent of ovarian tumors. Stomach is the most common primary location in 70 percent of cases, followed by colon, appendix, and breast. The prognosis is poor and its evolution is rapid. Objective: to describe a case of a patient with Krukenberg tumor.Case presentation: a 53 year old woman was consulted due to menopausal bleeding in stains and lower abdomen pain. She had personal history of gastric carcinoma, gallstones, breast nodule and hypertension. Gynecologic sonographic study was performed with positive tumor markers for ovarian cancer and negative tumor markers.Results: intraoperative finding: fibroid uterus and both ovaries were loculate, smooth surface coating of mucinous content with solid areas of color and adverse heterogeneous consistency was observed. Hysterectomy with oophorectomy was performed.Conclusions: Krukenberg, metastatic ovarian tumor is a rare entity with poor prognosis after diagnosis. Still, resection of the metastatic lesion is the first recommendation which appears to improve survival, followed by palliative systemic therapy.

Krukenberg tumor in a young woman: A rare presentation.

Krukenberg tumors mostly occur after 40 years. Metastatic ovarian tumors in young age are very rare and reported to be 2% of all the cases. Thirty percent of all ovarian neoplasms occurring during childhood and adolescence are malignant. A 25-year-old woman, parity- 2, presented with abdominal distension, pain in abdomen and amenorrhea. On examination, 18 weeks lump was palpable, fi rm to hard in consistency, non-tender and mobile. On ultrasonography bilateral ovarian tumors were reported, without any peritoneal free fl uid. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed. Microscopic examination revealed signet ring cells with glandular differentiation, diffusely invading the ovarian parenchyma. Tumor cells exhibited strong, diffuse immunopositivity for CEA with focal strong immunopositivity for CK7 and CK20 and immunonegativity for SATB2. Diagnosis of Krukenberg tumor was made. Endoscopic biopsy confi rmed the diagnosis of adenocarcinoma stomach. This case is reported because of its rarity in younger age group.

Gastric Cancer Presenting as a Krukenberg Tumor at 22 Weeks' Gestation

Gastric cancer is rare during pregnancy, and often advanced upon presentation. A Krukenberg tumor presents a diagnostic and therapeutic challenge in the pregnant patient. We present a case of a 38-year-old woman at 22 weeks' gestation who presented with worsening epigastric pain, and was found to have a left pelvic mass on ultrasound, which was confirmed by magnetic resonance imaging. She went into active labor and delivered a viable infant via vaginal delivery. An exploratory laparotomy revealed a large mass originating from her left ovary and diffuse thickening of the lesser curvature of the stomach. Frozen section investigation revealed the presence of signet cell adenocarcinoma. Subsequent upper endoscopy showed linitis plastica, while biopsy confirmed the presence of adenocarcinoma. In conclusion, the occurrence of gastric cancer in pregnancy is rare despite extremely common symptoms. The management poses a challenge because of the need for early treatment, and the continuation of the pregnancy.

Fibroma ovárico con células estromales en anillo de sello: un tumor extremadamente infrecuente: diagnóstico diferencial del tumor de Krukenberg / Ovarian fibroma with stromal signet-ring cells: differential diagnosis of Krukenberg tumor

La presencia de "células en anillo de sello" en el tejido ovárico es el marcador histológico clásico del tumor de Krukenberg. Un adenocarcinoma metastásico altamente agresivo y de baja sobrevida. En cambio, los fibromas ováricos son tumores del estroma generalmente benignos. Presentamos un caso muy infrecuente de fibroma celular con presencia de células en anillo de sello y revisamos los criterios para el diagnóstico diferencial con el tumor de Krukenberg.

The presence of signet-ring cells in ovarian tissue is classically described as histological marker of Krukenberg tumor. It is highly aggressive metastatic adenocarcinoma with low survival. In contrast, ovarian fibroid is a stromal tumor usually benign. We present a very rare case of cellular fibroma with presence of signet-ring cells and we review the criteria for differential diagnosis of Krukenberg tumor.

The aim of this article is to demonstrate the complexity of this diagnosis, the therapeutic approach, and the pessimistic prognosis that this condition has.

Adenocarcinoma mucoproductor de colon con infiltración de estómago y metástasis ováricas (tumor de Krukenberg) / Colon mucoproducing adenocarcinoma with stomach infiltration and ovarian metastases (Krukenberg's tumor)

Se presenta una paciente femenina de 29 años, operada de urgencia por presentar un gran tumor que incluía cuerpo gástrico y colon trasverso, con una perforación gástrica. Se realizó una gastrectomía subtotal con colectomía trasversa en bloque que incluyó el epiplón mayor. El diagnóstico histológico fue adenocarcinoma túbulo papilar mucoproductor de origen colónico, que infiltra hasta la serosa y pared gástrica. Se realizó tratamiento adyuvante con poliquimioterapia. Diez meses después presenta un tumor en hipogastrio, que al tacto vaginal, correspondía a los órganos genitales, sospecha clínica que confirman el ultrasonido abdominal y la tomografía axial computarizada. El hallazgo transoperatorio fueron tumores voluminosos de ambos ovarios, y otro tumor que afectaba la unión rectosigmoide. Se realizó una histerectomía radical con ooforectomía bilateral y sigmoidectomía, se reseca la porción proximal del recto, y se cierra tipo Hartman. El diagnóstico histológico final fue metástasis en serosa uterina e intestinal, y en ambos ovarios de adenocarcinoma mucoproductor, túbulo papilar de intestino previamente diagnosticado (tumor de Krukenberg). Se complementó el tratamiento con poliquimioterapia adyuvante(AU)

This is the case of a woman aged 29 operated on of emergency due to a tumor involving gastric body and transverse colon with gastric perforation. A subtotal gastrectomy with block transverse colectomy including the greater omentum was carried out. The histological diagnosis was a mucoproducing papillary tubular adenocarcinoma of colonic origin infiltrating to serosa and gastric wall. An adjuvant treatment was applied with poly-chemotherapy. Ten months later appears a hypogastric tumor which at vaginal manual examination corresponding to genital organs, clinical suspicion confirmed by abdominal ultrasound and computerized axial tomography. The transoperative findings were bulky tumors of both ovaries and another tumor involving the rectosigmoid joint. A radical hysterectomy with bilateral oophorectomy and sigmoidectomy was carried out with resection of proximal rectal portion with type Hartman closure. The final histological diagnosis was a metastasis in uterine and intestinal serosa and in both ovaries a mucoproducing adenocarcinoma, previous papillary tubule was also diagnosed (Krukenberg's tumor). Treatment was applied using adjuvant poly-chemotherapy(AU)
