Although clear cell adenocarcinoma have been described focally mimicking nephrogenic adenoma, we have identified a subset of clear cell adenocarcinoma that diffusely resembles nephrogenic adenoma (nephrogenic adenoma-like clear cell adenoca…
The authors reviewed the histologic slides of 2600 prostatic carcinomas seen at Memorial Hospital from 1963 to 1983. In ten cases, resection specimens had a predominantly endometrioid appearance. Six patients had polypoid lesions in and aro…
