[Evanescent carcinoma of the prostate. Incidence, clinical and histopathological characteristics.]

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.

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.

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).

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.
