A 12-year-old boy presented to the andrology department in June 2013 with left testicular pain that he had had for 6 months. There was no history of recent trauma, infection, hydrocele, or undescended testis. He denied having any urinary or constitutional symptoms. Physical examination revealed a hard, tender, 10 mm × 10 mm × 8 mm testicular nodule in the superior aspect of the left testis. The contralateral testicle was normal.\nScrotal ultrasonography (8 to 12 linear array transducer, LOGIQ P5, GE Healthcare, New York, New York State, USA) revealed 8 mm × 10 mm, hypoechoic homogeneous solid mass with unclear margin at the junction of the epididymis and left testis (). Serum tumor markers, including alpha-fetoprotein, beta-human chorionic gonadotropin, and lactate dehydrogenase, were all within normal limits. All preoperative laboratory tests, including complete blood count, biochemistry, and chest X-ray, were normal. A pelvic computerized tomography (CT) scan was negative for retroperitoneal metastasis. The provisional diagnosis was paratesticular tumor, with the possibility of benign nature.\nThe patient was then referred to our institution for surgical treatment. The left inguinal approach was established and the left spermatic cord was identified. On visual inspection, the tumor arose from the tunica albuginea protruding into the testis parenchyma. Intraoperative frozen-section biopsy showed benign tumor from tunica albuginea. Subsequently, a right tumor resection including removing a portion of tunica albuginea was performed.\nFinal histological examination confirmed the diagnosis of AT from the tunica albuginea (). Immunohistochemical analysis revealed the tumor cells were positive for calretinin, cytokeratin, and vimentin (). The postoperative course was uneventful. After 12 months of follow-up, the patient was asymptomatic without any evidence of local recurrence.
A 30 year-old male presented with a right-sided, tender scrotal swelling of four days’ duration. He had no significant past medical history or history of trauma. On local examination, a firm, mobile, and tender mass measuring 2 × 2 cm was found; the contralateral testis was normal. A clinical diagnosis of tuberculous epididymitis or testicular neoplasm was made. Routine hematological and biochemical investigations, urine analysis, and a chest radiograph revealed no abnormalities. USG of the scrotum showed a well defined, hypoechoic mass measuring 2.5 × 2 cm in the region of the globus major of the right epididymis. Aspiration was done using a 10 mL syringe and a 24 gauge needle to yield a scanty, grey-white aspirate. The smears were stained with H and E, Papanicolaou, and MGG stains. The cytological features were similar as those of case 1 and a diagnosis of an adenomatoid tumor was made. The patient underwent a conservative testis-sparing surgery with the excision of the epididymal nodule. The nodule measured 2 × 2 cm and the cut section was grey-white with microcysts. The results of the histopathological investigation were consistent with features of an AT.
