Resumen

El carcinoma micropapilar (CMP) es una variante anatomopatológica infrecuente de carcinoma vesical de comportamiento agresivo. Se presenta habitualmente como carcinoma de alto grado, en estadios avanzados y asociado a otras formas histológicas en proporciones variables. No manifiesta signos clínicos diferenciales con el carcinoma vesical típico. Los estudios de marcadores moleculares son todavía contradictorios. El tratamiento debería ser precoz y agresivo, fundamentalmente quirúrgico, dado que la Radioterapia y la Quimioterapia han demostrado escasa eficacia hasta el momento.

Presentamos el caso de un varón de 72 años con síntomas miccionales de larga evolución y hematuria macroscópica de reciente aparición que se diagnosticó de CMP en estadio avanzado. Al año de la cistectomía radical asociada a quimioterapia con carboplatino y gemcitabina se evidenció progression rápida de la enfermedad y falleció a los 14 meses.

Abstract

Micropapillary carcinoma is an uncommon pathologic variant of bladder carcinoma with aggressive behavior. Its usual presentation is like a high grade and high stage carcinoma and associated with other histologic types in different proportion. It doesn´t differ clinically from normal transitional cell carcinoma of the bladder. Studies of molecular markers are still contradictories. Treatment should be early and aggresive, based on surgical therapy as radiotherapy and chemotherapy have shown limited results.

We report a 72 years old man suffering from low urinary tract symptoms for years and recently presented gross hematuria. He was diagnosed as high stage micropapillary carcinoma. One year after radical cystectomy and subsequent chemotherapy based on carboplatin and gemcitabine , progression of the disease was shown on CT and the patient died 14 months after the diagnosis.
