Extramedullary plasmacytoma (EP) is that the progression of myeloma which will occur at any stage of the disease. EP is that the proliferation of plasma cells outside the bone marrow. the foremost common location for EP is that the head and neck. In rare instances it can involve connective/soft tissues and therefore the skin. This case will discuss the rare cutaneous presentation of additional medullary plasmacytoma. A 51 yo female presented to the emergency department complaining of difficulty walking thanks to acute onset of severe left thigh pain and right shoulder pain. No history of injury was noted. A right shoulder and left femur X-ray was completed showing lytic lesions and a pathological fracture of the femur. Bone biopsy resulted in features for myeloma. She was started on chemotherapy and through the course of disease she developed multiple cutaneous fumigated and ulcerated nodules. Punch biopsy resulted in plasmacytoma representing the rare presentation of cutaneous extra medullary plasmacytoma.
