ABSTRACT
Inverted papilloma of the prostatic urethra is an especially rare finding. A 75-year-old man with urinary retention wished to proceed with a holmium laser enucleation of the prostate (HoLEP) and was found to have a mass arising from his prostate vs bladder on preoperative imaging. Cystourethroscopy revealed the mass arising from the median lobe of the prostate. After transurethral resection and frozen analysis confirmed the benign pathology of an inverted papilloma, the patient subsequently underwent a successful HoLEP during the same surgical setting. Images of this rare prostatic mass are presented to increase urologist recognition and to assist management during HoLEP.

Objetivo: El papiloma invertido es una rara lesión polipoidea del urotelio, conocida como entidad diferente desde 1963, desde cuando escasamente se han publicado más de 100 casos en la literatura. Aunque su potencial maligno es todavía desconocido, existen varias publicaciones científicas en las que se denota. Métodos: Presentamos dos casos de papiloma invertido y hacemos una detallada revisión de la literatura científica al respecto. Resultados: Ambos pacientes fueron diagnosticados por el servicio de Anatomía Patológica de papiloma invertido, siguiendo controles periódicos posteriores y no apareciendo recidivas en ninguno de los dos casos, a los 24 y 18 meses de seguimiento respectivamente. Conclusiones: La posibilidad de que el papiloma invertido sea una lesión con potencial maligno debe ser en todo caso considerada y sugerimos que los pacientes con este diagnóstico sean sometidos a los exámenes urológicos de seguimiento en cualquier neoplasia vesical (AU)
Objective: Inverted papilloma is a rare polypoid lesion of the urothelium, known as a different entity since 1963. Not many more than 100 cases have been published. Although its malignant potential is still unknown, several scientific publications have noted it. Methods: We report to cases of inverted papilloma and perform a detailed bibliographic review. Results: Both patients were diagnosed by the Pathology Department and entered periodic follow-up visits, being free of recurrence at 24 and 18 months respectively. Conclusions: The possibility that inverted papilloma is a lesion with malignant potential should be considered in every case, and we suggest that patients with this diagnosis should enter a follow-up protocol like any bladder neoplasia (AU)

An inverted urothelial tumor (transitional cell carcinoma, inverted type, grade 1), consisting of a large (3.5 x 1.2 x 1.2 cm) tumor with stalk (0.3 cm in diameter) and surrounding broad base polypoid foci (0.5 x 0.6 x 0.5 cm altogether), was found in the lower segment of the left ureter of a 59-year-old man. He has taken oral anticancer drugs and kanpo medicine as a follow-up for 61 months, and is now free of disease. Differential diagnosis, inverted urothelial papilloma and carcinoma, and adequate treatment are discussed.
