Adenomatoid tumors are rare benign neoplasms of the paratesticular region, most commonly occurring at the tail of the epididymis. We present a case of adenomatoid tumor in a 65 year old male, known case of prostatic adenocarcinoma, who presented in Urology OPD with painless swelling in testis. Bilateral orchidectomy was done with clinical suspicion of testicular carcinoma. On histopathology, diagnosis of adenomatoid tumor of epididymis was made. Due to its rarity, it is important for the physician and pathologist to be aware of this interesting entity in order to make a correct diagnosis.
