Paratesticular Liposarcoma Masquerading as an Inguinal Hernia.

A man with left scrotal swelling felt to represent inguinal hernia underwent computed tomography scan for reported bleeding after prostate biopsy. Computed tomography scan revealed a 15-cm extratesticular left scrotal mass containing both fat and soft tissue components, raising concern for dedifferentiated liposarcoma. At surgery and pathology, the mass was separate from the left testis, epididymis, and spermatic cord. Histopathologic findings were consistent with paratesticular dedifferentiated liposarcoma.
