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 41 year old male presented to our department with left sided scrotal swelling and pain for fifteen days. There was no history of trauma or surgery. Local examination revealed a firm, tender nodule 2.5 cm in diameter. The contralateral testis was normal. Clinical diagnosis of testicular neoplasm/epididymal cyst was made. Investigations revealed normal serum α-fetal protein, human chorionic gonadotropin and lactate dehydrogenase levels. Scrotal ultrasonography revealed 2.5 cm well defined, heterogeneous, hypo echoic solitary mass in the left testis. Guided aspiration was done using 10 mL syringe and 24 gauge needle. Scanty, grayish white aspirate was obtained. Smears were stained with hematoxylin and eosin (H and E), Papanicolaou and May–Grόnwald-Giemsa (MGG) stains.\nModerately cellular smears consisted of tumor cells arranged in monolayered sheets and loosely cohesive clusters. Cells were round to oval with indistinct cell borders and moderate to abundant pale vacuolated cytoplasm. The monomorphic nuclei were eccentrically placed with fine granular chromatin and small inconspicuous nucleoli. Occasional binucleated cells were seen. Background showed pink amorphous material along with bare nuclei and few lymphocytes []. These cytological features suggested the diagnosis of AT. The patient underwent conservative testis sparing surgery, with excision of nodule.\nGrossly, an encapsulated grayish white mass measuring 2.5 × 2 × 1.8 cm was obtained. Microscopic examination revealed cuboidal to flat epithelial cells in solid cords, tubules and cystic spaces, some showing cytoplasmic vacuolation. Intervening stroma showed fibrocollagenous tissue with sparse lymphocytic infiltrate. Epithelial cells showed periodic acid schiff (PAS) positivity, the features consistent with adenomatoid tumor.
