The utility of ultrasound-guided tru-cut biopsy in the diagnosis of occult breast carcinoma presenting as ovarian malignancy with multiple metastases: A case of unknown primary

@#This paper documents the utility of ultrasound-guided tru-cut biopsy in the diagnosis and subsequent management of a case of occult breast carcinoma presenting with multiple distant metastases in the absence of a primary breast lesion. She was initially diagnosed as primary ovarian malignancy with metastatic disease and subsequently underwent transvaginal ultrasound-guided tru-cut biopsy of the right ovarian mass. Histologic and immunohistochemical studies were consistent with a metastatic adenocarcinoma of breast origin. The patient underwent chemotherapy for primary breast carcinoma and has responded well.

Diagnóstico de Metástasis Ováricas de un linfoma B diseminado mediante ecografía 3D / Diagnosis of Ovarian Metastases from disseminated B lymphoma using 3D ultrasound

RESUMEN La participación del aparato genitourinario en el contexto de la enfermedad hematológica maligna es bien conocida. No obstante, la afectación ovárica por linfomas es inusual, ya sea de novo o como manifestación tardía de linfoma diseminado. El objetivo de esta comunicación es exponer la aportación diagnóstica de la ecografía tridimensional (3D) en la detección de metástasis ováricas, cuando todavía algunas de las pruebas de imagen estándar como la tomografía computarizada (TAC) son normales. En este caso presentamos una paciente con linfoma B difuso de células grandes mediastínico de crecimiento rápido y diseminación precoz a aparato gastrointestinal y genitourinario.

ABSTRACT Genitourinary participation in the context of malignant hematologic disease is well known. However, ovarian involvement by lymphoma is unusual, either de novo or as late manifestation of disseminated lymphoma. The purpose of this communication is to show the diagnostic contribution of three-dimensional ultrasound (3D) in the detection of ovarian metastases, when still some of the standard imaging tests such as computed tomography (CT) are normal. Here we present a patient with primary mediastinal large B-cell lymphoma diffuse with fast growing and early dissemination to gastrointestinal and genitourinary tract.

Metástasis ovárica única de angiosarcoma mamario como localización infrecuente / Single ovarian metastases of breast angiosarcoma as unusual location

Los angiosarcomas son tumores vasculares extremadamente raros con alta tasa de proliferación e invasión. Están caracterizados por células anaplásicas que se originan en las paredes de los vasos sanguíneos. Poseen mal pronóstico debido a su comportamiento altamente agresivo, el cual condiciona una elevada probabilidad de recurrencia local y extensión multiorgánica. Se presentan principalmente en: pulmón, hígado, ganglios linfáticos y huesos. Su tratamiento es controvertido debido escasa casuística disponible acerca de esta estirpe tumoral, aunque parece claro que el tratamiento principal es la cirugía y que el tratamiento posterior puede ser la quimioterapia adyuvante(AU)

Angiosarcomas are extremely rare vascular tumors with high rate of proliferation and invasion. They are characterized by anaplastic cells originating in the walls of blood vessels. They have poor prognosis because of their highly aggressive behavior, which determines a high probability of local recurrence and spreading to multiple organs. They occur mainly in lung, liver, lymph nodes and bones. Treatment is controversial due to small number of cases available about this tumor type, although it seems clear that the main treatment is surgery and subsequent treatment can be adjuvant chemotherapy(AU)

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.

Metástasis ováricas de carcinoma de células pequeñas de pulmón / Ovarian metastases of small cell carcinoma oat-cell type of lung

La incidencia de cáncer de pulmón sigue aumentando, sobre todo en las mujeres y, aunque las metástasis en ovario son raras, hay que tenerla en cuenta en el estudio de extensión y seguimiento del mismo, porque en la mayoría de los casos en el momento del diagnóstico se verifica diseminación a distancia. Presentamos el caso de una paciente de 29 años en la que se planteó duda diagnóstica inicialmente entre tumor ovárico maligno con metástasis pulmonares versus linfoma, llegándose al diagnóstico final de carcinoma de células pequeñas tipo oat-cell de pulmón con metástasis ováricas.

The incidence of lung cancer is increasing, especially in women, and although metastasis in the ovary is uncommon it should be taken into account in the extension study and monitoring of the same because distant spread is verified in most cases at the time of diagnosis. We report the case of a 29-year-old patient which diagnostic doubt arose initially from malignant ovarian tumor with lung metastases or lymphoma, and she came to the final diagnosis of small cell carcinoma oat-cell type of lung with ovarian metastases.

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)
