A case of edematous striae distensae in lupus nephritis.

A 17-year-old girl with systemic lupus erythematosus presented with painful edematous abdominal striae. She had been treated with systemic steroid for the systemic lupus erythematosus. At the time of presentation, she had abruptly gained 10 kg due to combined lupus nephritis. The histopathologic finding of the edematous striae distensae included dermal edema with separation of collagen fibers and small fragmented elastic fibers. Edematous striae distensae are uncommon but can develop from the combined effects of glucocorticoid and generalized edema.
