A woman, aged 39, is presented from the Massachusetts General Hospital with an asymptomatic eruption on the anterior aspect of both legs which appeared following the birth of her third child seven years ago. Two years ago she consulted a dermatologist who found normal glucose tolerance, and a biopsy was performed.There are many circular plaques on both legs, some of which are discrete and others have coalesced. Earlier lesions have a reddish-brown color with a sharp margin composed of small papules. Older lesions show a yellowish discoloration with epidermal atrophy.
A complete blood count, fasting blood sugar level, total serum proteins, and the albumin-globulin ratio were all normal. Urinalysis was normal and the Hinton reaction was negative.Biopsy showed ill-defined areas of collagen degeneration associated with a mild inflammatory infiltrate of lymphocytes and histiocytes. Numerous giant cells were also present in the dermis.
