(A) Cutaneous necrosis of lower extremity. (B) Tc99m–labeled methylene diphosphonate full body bone scan showed diffuse increased uptake in the soft tissues of the bilateral calves and bilateral distal thighs (arrow). The above nonspecific findings can be seen in rhabdomyolysis, cellulitis, venous stasis, and diffuse myositis ossificans.

Pathologic findings in H&E–stained histologic sections. (A) A skin biopsy showed vascular ectasia, hemorrhage, and scattered inflammatory cells in the superficial dermis (original magnification 100×). Several small blood vessels in this location showed fibrinoid necrosis of their walls (inset, original magnification 400×). (B) The adipose tissue deep to the dermis had fat necrosis and contained blood vessels with extensive mural calcification and intravascular thrombosis (original magnification 200×). (C) Partial colonic resection revealed extensive ischemic damage, including an area of transition from viable mucosa at the left, to an area of ischemic type ulceration to the right (original magnification 40×). The mucosal layer shows loss of epithelium with coagulative necrosis and hemorrhage of the lamina propria. Edema and vascular congestion is observed within the submucosa. (D) Several medium-sized to large blood vessels in the mesentery had extensive mural calcification (original magnification 40×).19

Abdominal CT scan showed free air within the peritoneal cavity (arrowhead), as well as extensive vascular calcification involving the aorta, renal arteries including the segmental branches, and mesenteric arterial branches (arrow). The hepatic and splenic arteries also showed extensive vascular calcification (not shown on this image).
