[Bladder leiomyosarcoma: case report]. / Leiomiosarcoma vesical: aportacion de un nuevo caso.

OBJECTIVES: To report a new case of bladder leiomyoma in an adult. METHODS: 64-year-old female patient consulting for a four-month hematuria diagnosed of a bladder intraluminal tumor on ultrasound during a routine gynecologic revision. Cystoscopy confirmed the presence of the tumor. Transurethral resection was indicated. RESULTS: Pathology reported a definitive diagnosis of leiomyosarcoma. Anterior pelvic exenteration was subsequently performed. On one year follow-up there is no evidence of disease. CONCLUSIONS: We emphasize the rarity of these neoplasias. We comment on their main characteristics, pointing out the importance of immunohistochemical staining for the definitive histological diagnosis. We refer the therapeutic options described in the literature.

Leiomiosarcoma vesical: aportación de un nuevo caso / Bladder leiomyosarcoma: case report

OBJETIVO: Presentación de un nuevo caso de leiomiosarcoma vesical en adulto.MÉTODO: Describimos el caso de una paciente mujer de 64 años que refiere hematuria de cuatro meses de evolución,y a la que se detecta ecográficamente durante revisiónginecológica rutinaria una neoformación intraluminal vesical. La cistoscopia permitió confirmar la existencia de dicha lesión. Se indicó resección transuretral de la misma.RESULTADOS: El estudio anatomopatológico permitió un diagnóstico definitivo compatible con leiomiosarcoma. Se procedió en un segundo acto quirúrgico a la realización de exanteración pélvica anterior. No evidencia de recidiva tras un año de la cirugía.CONCLUSIONES: Destacamos la infrecuencia de este tipo de neoplasias. Comentamos las principales característicasde las mismas, señalando la importancia de las técnicas de inmunohistoquímica de cara a su diagnóstico histológico definitivo. Hacemos referencia a las posibilidadesterapéuticas descritas en la literatura

[Infiltrative small cell carcinoma of the bladder. New case report: treatment with radical surgery and chemotherapy]. / Carcinoma vesical infiltrante de celulas pequeñas. Descripcion de un nuevo caso tratado con cirugia radical mas quimioterapia.

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.
