A 29-year-old man with chronic lymphedema in the left lower extremity for 8 years presented with an enlarging and ulcerated nodular plaque on his left leg. The lesion had started out as a bruise, then progressively enlarged and ulcerated over 4 months. He went to many physicians during this time and was tested and/or treated for possible infection, deep vein thrombosis, vasculitis, anda torn muscle. The patient's family history was remarkable in that his mother and sister both have chronic bilateral lymphedema.
