OBJECTIVE: To determine the incidence and clinical and histopathological characteristics of patients with prostatic evanescent carcinoma in the Urology Department of the Hospital Universitario de Caracas. METHODS: We reviewed the medical records of 257 patients undergoing radical prostatectomy for a previous diagnosis of prostatic carcinoma in the period January 2010 to June 2016. RESULTS: Four patients had evanescent carcinoma corresponding to 1.55%, similar to documented studies, thus maintaining their percentage of appearance in time. Adenocarcinomas are usually associated with Gleason scores ≤6, but they can present in carcinomas with less differentiated histopathological pattern, like Gleason 7 (3 + 4). CONCLUSIONS: In the pathological study of the specimen of radical prostatectomy of patients with evanescent carcinoma, it is advisable to apply additional immunohistochemistry technique or seek for a second pathological opinion, to confirm this entity, and to rule out a technical or interpretation failure.
