title: Anhidrosis (hypohidrosis) in Sjögren's syndrome.
abstract: There has been a relative lack of literature on the association of hypohidrosis in Sjögren's syndrome with any lesion having specific histologic findings. We looked at a recent case presentation of a 55-year-old man with complaints of dry mouth and dry eyes, becoming easily overheated in direct sunlight, and having difficulty in perspiring. Physical examination showed fissuring and atrophy of the tongue and angular cheilitis. A punch biopsy of the skin showed a moderate number of eccrine gland and ductal structures in the lower reticular dermis, each surrounded by a dense cellular infiltrate of plasma and lymphocytic cells. Our patient also had a markedly decreased sweating response to methacholine. In reviewing the literature as far back as 1951 and on the basis of findings in our present case study, we conclude that it seems probable that the severity of the skin disease is an important determining factor in predicting whether the sweat gland lesion does exist.
