Tumours and tumour-like conditions of the para-testicular region--a study of morphological features

Indian J Pathol Microbiol. 1998 Jul;41(3):287-95.

Abstract

Twenty two patients with tumours or tumour-like conditions of the para-testicular region (PTR) were diagnosed over a 5 year period. Of these, 16 (73%) were benign with only one true neoplasm (papillary cystadenoma). The tumour-like conditions were comprised of 6 cases of adenomatous hyperplasia of epididymis, 4 cases of spermatic granuloma, 2 cases each of spermatocele and nodular-fibrous proliferation and one mesothelial cyst. Three patients with spermatic granuloma gave a history of trauma. No case of adenomatoid tumour was encountered. Six malignant neoplasms were diagnosed (27%) all of which were sarcomas. Five were primary to the PTR and one was a metastatic deposit from a primary leiomyoblastoma of the mesentery. Among the 5 primary sarcomas were 2 cases each of rhabdomyosarcoma and leiomyosarcoma, and 1 case of liposarcoma. The patient with leiomyoblastoma presented first with a measenteric mass which was followed a month later by a rapidly growing mass in the scrotum. Immunohistochemical staining (IHC) and Electron microscopy (EM) were done in this case. Intra-cytoplasmic myofilaments as well as desmosomes were observed. The patients ranged from 14 to 65 years of age and most presented with painless mass in the scrotum. Follow-up was not possible due to practical difficulties.
