An unusual testicular mass : a case of desmoplastic small round cell tumour

Initially, this was an extremely difficult case to manage and diagnose clinically. Ultimately, patho-logical assessment of the resected specimen, along with cytogenetics, was required to make the diagnosis. The clinical differential diagnosis of testicular masses in a young male very rarely includes this tumour. Histologically, in the peritoneum in a young male, this tumour can be easily recognised but might not be initially thought of, especially with this presentation and the rarity of this entity in this location. This case is also a harrowing tale of the dangers of non- compliance. This is an extremely aggressive tumour, and delays to diagnosis and treatment by even a few months may diminish overall survival.
