Syringolymphoid hyperplasia with alopecia is an uncommon skin disorder
described in 1969 by Sarkany. Since then only three additional cases
have been reported, all in the European literature. We present a 59-ye
ar-old man with two persistent hyperpigmented hairless patches of 13 y
ears duration. Biopsy specimens revealed characteristic hyperplastic c
hanges of the eccrine glands and ducts and a dense lymphocytic infiltr
ate surrounding eccrine structures with ''syringotropism''. Perifollic
ular lymphocytic infiltration and changes consistent with follicular m
ucinosis and mycosis fungoides were also present. Imunophenotyping and
gene rearrangement studies showed the cells to be primarily of the T
helper phenotype with rearrangement of the surface receptor gene.
