Spermatocytic tumor of testis: A case series of 26 cases elucidating unusual patterns with diagnostic and treatment dilemmas.

BACKGROUND

Spermatocytic tumours are a rare subset of testicular tumours seen in elderly patients with distinct clinicopathological features and a favourable outcome. The typical presentation and characteristic histological features usually suffice for the diagnosis. Most of the cases are amenable to surgical excision. However, occasional cases which have a sarcomatous transformation may behave more aggressively and warrant adjuvant therapy.

METHODS

We present the clinicopathological features of a series of 26 cases diagnosed as Spermatocytic tumour at our tertiary cancer institute from 2002-2019.

RESULTS

Twenty-four of these cases had the typical cytological features of a spermatocytic tumour while two cases showed sarcomatous change, one with rhabdomyosarcomatous differentiation and the other being an undifferentiated spindle cell sarcoma. Although the tumor can show varied patterns, the tripartite cytomorphology is typical in all cases.

CONCLUSIONS

Careful note of these patterns and variations in histology is essential to prevent an erroneous diagnosis of other testicular neoplasms and guide the therapy.
