Systemic lupus erythematosus and concurrent cytomegalovirus vasculitis: diagnosis by antemortem skin biopsy.
A 45-year-old woman with a 4-year history of systemic lupus erythematosus (SLE) developed fever, decreased visual acuity and skin ulceration. A biopsy of a cutaneous ulcer demonstrated small vessel vasculitis with characteristic cytomegalovirus (CMV) inclusions in the vascular endothelium. The presence of CMV was confirmed by DNA hybridization immuno-histochemistry. Retinal artery vasculitis, previously associated with flares of her SLE, was also noted on ophthalmologic examination. Our case demonstrates that CMV infection can mimic the cutaneous manifestations of collagen vascular disease and that early identification can be made by biopsy of suspicious skin lesions.
