The prostatic ductal adenocarcinoma (PDA), a uncommon histological subtype of prostatic carcinoma, was first described as âendometrioid carcinomaâ by Melicow and Patcher in 1967, due to its histological resemblance to endometrial carcinoma ().In the following literatures, PDA was thought to arise from prostatic utricle that belongs to a remnant of müllerian duct structure, even to ⦠67 year old man with squamous cell carcinoma of the prostate (Case Reports in Clin Pathol 2016;3:60) 76 year old man with renal-like clear cell carcinoma, positive for CD10 and PSA (In Vivo 2020;34:2751) 9 cases of patients ranging from 42 - 78 years with rectal adenocarcinoma (Hum Pathol 2007;38:1836) 16 prostate needle biopsies with distorted benign rectal glands that mimic prostate ⦠Carcinoma Includes all adenocarcinomas and histologic variants, neuroendocrine carcinomas, and other types.
