[Soft tissue metastases by micropapillary bladder carcinoma. Metastatic disease]. / Metástasis en partes blandas por un carcinoma micropapilar de vejiga.

Micropapillary transitional cell carcinoma is a rare (incidence of 0.7%) and highly aggressive variant of bladder carcinoma. Morphologically, it is characterized by small tight clusters of neoplastic cell floating in clear spaces resembling lymphatic channels. Its usual presentation is like a high grade and stage carcinoma and most often is associated with a variable component of conventional carcinoma or other variants. The usual sites of bladder cancer metastases are the lymph nodes, lungs, bone and liver. Soft tissues metastases from transitional cell carcinoma of the bladder occur infrequently. We report the cases of a 77-year-old man presenting with an abdominal soft tissue mass a six years after local excision of a micropapillary bladder carcinoma.

[Hyperplasia of adrenal rests in the testicle: a rare cause of male infertility]. / Hiperplasia de restos adrenales en el testículo: una causa infrecuente de infertilidad masculina.

We report the case of a 37-year-old man with infertility caused by bilateral testicular masses secondary to congenital adrenal hyperplasia (21-hydroxylase deficiency). Testicular biopsy was done and its was initially interpreted as Leydig cell tumor but after clinical information was histologically reclassified as tumor of the adrenogenital syndrome. The differential diagnosis with Leydig cell tumor is discussed and it must be established through the clinical, biochemical, radiological and pathological features.

Metástasis en partes blandas por un carcinoma micropapilar de vejiga / Soft tissue metastases by micropapillary bladder carcinoma. Metastatic disease

El carcinoma micropapilar es una variante infrecuente de carcinoma vesical (incidencia del 0.7%) con comportamiento clínico agresivo. Histológicamente está constituido por nidos pequeños de células uroteliales dispuestas en lagunas que simulan invasión vascular y se suelen asociar a estadios clínicos avanzados y alto grado histológico. Estos tumores generalmente se asocian a otras variantes histológicas de carcinoma transicional. Los tumores de vejiga suelen metastatizar a ganglios linfáticos, pulmón, hueso e hígado, pero son excepcionales las metástasis a partes blandas. Presentamos el caso de un varón de 77 años que presentó una masa metástasica en partes blandas de pared abdominal a los 6 años de realizarle resección de un carcinoma transicional variante micropapilar de vejiga

Hiperplasia de restos adrenales en el testículo: una causa infrecuente de infertilidad masculina / Testicular adrenal rest issue hyperplasia: an unusual cause of male infertility

Presentamos un caso de azoospermia secretora y masas testiculares bilaterales secundarias a hiperplasia adrenal congénita por déficit de 21-hidroxilasa en un varón de 37 años. La biopsia testicular fue informada como tumor de células de Leydig, pero se consideró el diagnóstico después de la información clínica, siendo el diagnóstico final de hiperplasia de restos adrenales en el testículo. Comentamos el diagnóstico diferencial con el tumor de células de Leydig insistiedo en la necesidad de diagnosticar esta lesión con una adecuada correlación clínica, analítica, radiológica e histológica (AU)
