ABSTRACT

El mesotelioma peritoneal maligno es un tumor de presentación infrecuente, diagnóstico difícil y comportamiento agresivo en la mayoría de los casos. Presentamos el caso de una mujer de 80 años con una formación pélvica que depende de útero con carcinomatosis peritoneal, abundante líquido ascítico e infiltración de recto y vejiga. Se decide realizar un estudio histológico de la masa para después comenzar con quimioterapia paliativa por estado avanzado de la enfermedad. Se indica una minilaparotomía y se realizan múltiples biopsias. La histología y la inmunohistoquímica de la pieza son compatibles con un mesotelioma peritoneal maligno de tipo mixto (epitelial y sarcomatoide). La paciente comienza con evolución desfavorable y se deciden medidas de soporte paliativo. Fallece a los 15 días poscirugía. En mujeres con afectación de órganos genitales es importante hacer el diagnóstico diferencial con los tumores serosos de origen ginecológico puesto que los protocolos de tratamiento quimioterápico son diferentes (AU)


Malignant mesothelioma of the peritoneum is an infrequent tumor that is difficult to diagnose and usually behaves aggressively. We present the case of an 80-year-old woman with a pelvic mass of uterine origin, peritoneal carcinomatosis and abundant ascites. Histologic study of the mass was requested and palliative chemotherapy was started because of the advanced stage of the disease. A minilaparotomy was performed and multiple biopsies were taken. Histologic and immunochemistry studies were compatible with a mixed (epithelial and sarcomatoid) malignant mesothelioma of the peritoneum. Prognosis was poor and palliative care was provided. The patient died 15 days after surgery. In women with involvement of the genital organs, it is important to make a differential diagnosis with serous tumors of gynecologic origin because the chemotherapy protocols differ (AU)

ABSTRACT

BACKGROUND: To make the difference between two uncommon entities, small cell prostate carcinoma and prostatic metastasis of small cell lung cancer. METHODS: We describe a case of single extrapulmonar metastasis in the prostate from small lung carcinoma. RESULTS: We describe a case of single extrapulmonar metastasis in the prostate from small lung carcinoma. CONCLUSIONS: Clinical and radiographic findings and inmunohistochemistry allow differential diagnosis.

ABSTRACT

Introducción: El nefroma mesoblástico congénito (NMC) (hamartoma leiomiomatoso o mesenquimal) es una neoplasia renal congénita. Se diagnostica en los seis primeros meses de vida. Su comportamiento clínico es benigno y el tratamiento es quirúrgico. Paciente y métodos: Describimos el caso de un paciente de una semana de edad que presenta una masa renal. En la ecografía es sólida y sustituye al riñón. El TAC muestra una lesión con márgenes mal delimitados y la estructura heterogénea. Macroscópicamente en la pieza quirúrgica se identificaba una masa intrarrenal bien delimitada, sólida, homogénea, blanquecina y con aspecto fasciculado. Microscópicamente se observa una neoformación compuesta por una población monótona de células fusiformes dispuestas en haces entrelazados. La lesión carece de cápsula y en la interfase con el parénquima renal normal hay células tumorales que rodean a los túbulos y a los glomérulos. Conclusiones: La edad en el momento del diagnóstico y la correcta extirpación del riñón son los dos factores pronósticos más relevantes


Introduction: Congenital mesoblastic nephroma (CMN) (leiomomatous or mesenchymal hamartoma) is a benign congenital renal neoplasm. This tumor is usually diagnosed along the first six months of life and surgery is current treatment. Patient and methods: A one week of life patient with a renal mass is reported. Ultrasonographically, the mass appearance was solid and replaces the kidney. Computerized tomography (CT) showed a lesion with irregular margins and heterogeneous structure. Grossly, a well delimited intrarenal mass, white, solid, homogeneus and fasciculated was identified. Microscopically, the tumor was composed by a monotonous population of fusiform cells showing an interlacing fasciculated pattern. The mass lacks capsule and the interphase with normal renal parenchyma showed spindle cells surrounding renal tubuli and glomerula. Conclusions: Best prognostic factors are the adequate extirpation and age at the diagnosis
