A 32-year-old man form the Indian subcontinent presented to the emergency department 2 days after having been kicked in the scrotum during a football match with increasing pain and swelling of the right hemiscrotum. A firm discrete mass was noted at the lower pole of the right epididymis that was clinically inseparable from the otherwise unremarkable testicle. The right testicle was nontender and sat in a normal position with no signs of scrotal skin ecchymosis. The history suggested that the scrotal mass had been present for approximately 12 months, and a preliminary diagnosis of a haemorrhagic cyst caused by trauma was made. Initial management included scrotal support, analgesia, and a follow-up magnetic resonance imaging (MRI) scan. The MRI confirmed a 2.3 cm irregular lesion arising posterior to the lower pole of the right testis that enhanced peripherally with central necrosis and therefore could not rule out a potentially malignant lesion (). After informed consent, a scrotal exploration and epididymectomy was performed. Grossly, the specimen measured 25 mm in maximum diameter. Sectioning revealed a 20 mm yellow, partly necrotic tumour mass ().\nHistological examination (H+E) showed a central area of coagulative necrosis with surrounding reactive fibroblastic tissue and inflammation (). Irregular clusters and solid nests of viable epithelioid cells were present, partly obscured by the fibroblastic tissue reaction ().\nOn immunohistochemical staining, these epithelioid cells were positive for CAM5.2 and CK7 and also expressed the mesothelial markers calretinin and WT1 (). The H+E appearances and immunoprofile were consistent with a partly necrotic/infarcted adenomatoid tumour. No evidence of malignancy was seen. The tumour was well circumscribed and completely excised at all margins. The patient was informed of the results, reassured, and discharged from further followup.
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.
