چکیده
A 47-year-old woman was referred to Washington University dermatology clinic for a nonhealing ulcer on her right shin of 8 months’ duration. She reported having had a similar ulcer on her left shin 6 years ago. The patient’s medical history was significant for non–insulin-dependent diabetes mellitus, hypertension, and osteoarthritis. On examination, she was found to have a 2 3-cm punched-out ulcer with rolled borders on her right shin. Evaluation of a biopsy specimen taken 6 months prior to presentation showed extensive dermal necrosis with ulceration and abscess formation and microangiopathy manifested by thickening of the capillary walls with fibrinous deposits and microthrombi. The overall histologic findings were thought to be most consistent with atrophie blanche.
