Testicular sclerosing stromal tumour: A report of two cases documenting GLI1 alterations.

This article reports on two cases of testicular sclerosing stromal tumors (SSTs) that show GLI1 gene alterations. SSTs are neoplasms that were first described in the ovary in 1973 and are characterized by lobulated microscopic appearance. The patients in these cases were aged 35 and 65 years and presented with testicular masses. The tumors demonstrated large areas of hypocellular myxoid/oedematous stroma with scattered hypercellular areas. Both tumors expressed nuclear GLI1. The article suggests that these findings support the existence of rare SSTs in the testis and their potential pathogenesis related to ovarian SSTs. [Extracted from the article]
