[Infiltrative small cell carcinoma of the bladder. New case report: treatment with radical surgery and chemotherapy].

OBJECTIVES To report a new case of infiltrative small cell bladder cancer. METHODS We describe the case of a 60-year-old male patient who consulted for monosymptomatic hematuria over a few weeks. Cystoscopy showed a neoplasia in the anterior wall of the bladder. Pathological analysis of the TUR chips was compatible with infiltrative small cell tumor. After a negative staging study radical cystectomy plus adjuvant chemotherapy were indicated. RESULTS Pathological study of the surgical specimen confirmed the diagnosis with involvement of the surrounding fat. There is no evidence of neoplasic involvement after 24 months follow-up. CONCLUSIONS We point out the validity of a radical surgical approach for this tumor, also emphasizing the importance of adjuvant chemotherapy. We concur with other authors in the need of multicentric studies to outline the most effective surgical option, due to the limited number of cases of this entity.
