A 52-year-old male presented with complaints of a painless nodule in right scrotal sac for last 2-years that was gradually but very slowly increasing in size. There was no history suggestive of urinary infection, genitor-urinary tuberculosis or epididymo-orchitis. Examination revealed a pea-sized firm, well-marginated, smooth swelling present at the lower pole of testis but that could not be separated with epididymis. Testicular sensation was normal and cord and rest of the epididymis was normal. Serum level of α-fetoprotein and β-HCG were normal. Scrotal ultrasonography revealed a solid mass at the lower pole of right testis that was relatively hyperechoic as compared to the testicular parenchyma []. Scrotal MRI revealed a well-defined lenticular lesion at lower part of right testis. The lesion displayed signals isointense to slightly hypointense on both T1- and T2-weighted images with adjacent hypointense band. The interface with the testis was maintained []. Fine-needle aspiration from the mass revealed absence of malignant cells. In view of long clinical history, negative tumor markers, findings typical of adenomatoid tumor on sonography and MRI, as reported previously,[] and absence of malignant cells on cytology local excision was performed under local anesthesia through inguinal incision. At exploration, there was a hard mass on the lower pole separate from the epididymis. Histopathology confirmed it to be an adenomatoid tumor.
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.
