A Case of Three Upper Extremity Lesions of Mobile Encapsulated Fat Necrosis in One Patient.

Mobile encapsulated fat necrosis is a benign condition that presents as a freely mobile nodule or cluster of nodules beneath the skin. We report a case of an elderly female with a complex medical history who presented with three mobile lesions on the left upper extremity shortly after undergoing a leg amputation, all determined to be mobile encapsulated fat necrosis at different stages of formation. This unusual presentation has not been well described in the literature and highlights the potential for associations with specific underlying medical conditions.
