Femoral sheath lipoma causing venous obstruction syndrome

Abstract

Lipomas are benign, encapsulated, soft-tissue tumours composed of well-differentiated adipocytes. They arise in the subcutaneous tissue typically on the back, shoulder and neck. Lipomas have been known to cause symptomatic obstruction to venous flow by compression. We report a case of venous obstruction syndrome due to a small lipoma within the femoral sheath.
