Lichen sclerosus et atrophicus generalisata, alopecia areata, and polymyalgia rheumatica found in the same patient

A sixty-eight year old woman with lichen sclerosus et atrophicus since the age of fity-two, alopecia totalis since the age of thirty-six, and polymyalgia rheumatica since the age of fifty-eight is presented. Besides alopecia totalis, the patient has typical lichen sclerosus et atrophicus changes on the trunk, upper arms, and thighs, and at the first visit an ulcer on her left breast. An immunologic link between her three diseases is suspected. As shown in this case Wood's light is of great value in depigmented skin changes.
