A rare case of para-testicular dedifferentiated liposarcoma: a diagnostic dilemma

Paratesticular dedifferentiated liposarcoma (DD-LPS) are rare neoplasms. It has been estimated that 12% of DD-LPS occur in the paratesticular region, while the retroperitoneum is the most common site for this tumor. Herein, we presented a case of a 66-year-old male with a history of pedal edema and right scrotal swelling, CT scan shows a solid mass arising from the right side of the scrotum. Following this, a radical orchiectomy of the right testis with mass was performed, and after thorough microscopic and immunohistochemistry positive for MDM2 and CDK4, the diagnosis of low-grade dedifferentiated liposarcoma was given. This case report expands the morphologic spectrum of dedifferentiated liposarcoma and emphasizes the need to consider these tumours in the differential diagnosis of other neoplasms.
