Adenomatoid Tumor Of Tunica Albuginea Mimicking A Testicular Neoplasm

摘要

Adenomatoid tumors arising from the tunica albuginea of the testis are rare lesions. We describe a case of a large adenomatoid tumor of the tunica albuginea measuring 4 cms. Because of its rarity, the clinical and histopathological aspects are discussed. Introduction Adenomatoid tumors are benign mesothelial tumors found in the paratesticular region, mainly arising from the epididymis. The average documented size is 2 cm1. Here, we report a case of adenomatoid tumor originating in the tunica albuginea of the testis, measuring 4x3.5cms and mimicking an intratesticular neoplasm. Clinical Summary A 40 year married male, presented with a dull ache and dragging sensation in the right hemiscrotum for last one year. It was associated with a gradual increase in the size of the right testis. The pain was not relieved with analgesics. A fine needle aspiration of the right testis done at another hospital and was reported as Seminoma. Thereafter, he was referred to our institute for further treatment.On examination, the right testis was found to be slightly irregular at the lower pole. There was no palpable varicocele or hernial sac. The contralateral testis was normal. Investigations revealed normal serum α-FP, β-HCG, and LDH levels. A scrotal Doppler showed a hypoechoic lesion at the junction of the epididymis and the right testis. The patient underwent right radical orchidectomy as features were suggestive of a neoplastic process. Pathological findings Grossly, the orchidectomy specimen weighed 95gms and measured 5.5 x 3cms (Fig.1).
