A case report of scrotal lipoma and review of lipoma pathogenesis.

Scrotal lipoma is a type of rare benign mesenchymal tumor. These lipomas can masquerade as inguinal hernias that can cause surgical dilemmas. The size of lipomas can vary, with some growing into remarkably large masses. We present a case of a 75-year-old male with a history of laparoscopic hernia repair, who noticed a progressively enlarging left scrotal bulge. An open hernia repair procedure was performed, unexpectedly revealing two large left-sided scrotal masses, which were subsequently excised. Based upon the histopathologic findings of these masses, scrotal lipomas with fat necrosis were diagnosed.
