Traumatic fat necrosis; a case report.

Sir, Panniculitis has a multiple aetiology. One of the less common causes is trauma and hence traumatic fat necrosis. These soft tissue injuries usually appear on the shins, thighs, breasts, arms and buttocks. Women are particularly susceptible (1, 2). The initial injury is usually bruising of the skin with a haematoma, and later deeper indurated lesions can be palpated (2, 3). Traumatic panniculitis is a benign subcutaneous lesion with a distinct histological appearance. Focal liquefaction can occur in the injured fat, leading to discharge (2, 4). We describe an interesting case of a male patient with a fat necrosis developing into a discharging wound. The histology confirms the diagnosis.
