A rare instance of adenomatoid tumor of epididymis: a case report

Adenomatoid tumors are uncommon benign growths that usually occur in middle-aged men. Originating from mesothelial cells and are primarily found in the area near the testicles, especially at the tail of the epididymis. A clear diagnosis of the tumor is important to distinguish it from more aggressive intrascrotal tumors based on clinically and imaging tests. Overall, the prognosis for individuals with adenomatoid tumors of the epididymis is excellent, with less risk of recurrence or complications following surgical removal.

This article reports on an 18-year-old male with a history of small painless mass in the scrotum around the right testis for 6 months not growing in size. There were no significant complaints related to genitourinary system nor did the patient have any past medical or surgical history. On local examination, a 2 × 2 cm² well defined, nodular, solid, firm mass was palpable adjacent to the head of right epididymis.

Adenomatoid tumor of the epididymis are rare benign neoplasm of mesenchymal origin. These tumors mostly being asymptomatic are often misdiagnosed. In this patient, all the systemic examinations and Lab reports were normal and scrotal ultrasound failed to provide the exact diagnosis which eventually was proven on the histopathology section. The nodule was removed on local anesthesia. The patient was counseled and followed up routinely.

The case report emphasizes the significance of early diagnosis of adenomatoid tumor and differentiates it from other similar intrascrotal masses which is crucial to avoid unnecessary interventions for patients.
