Histopathologic examination of the biopsy specimens revealed a slightly acanthotic epidermis, with reticular fibroplasia of the papillary dermis. Intermediate-size lymphocytes with atypia were seen focally along the dermoepidermal junction. The eccrine coils were densely infiltrated with intermediate-size lymphocytes. Immunohistochemical analysis showed a CD4:CD8 ratio of greater than 10:1, and T-cell receptor gene rearrangement studies showed a positive T-cell clone. The diagnosis of syringotropic MF was made.
DISCUSSION
Mycosis fungoides has a wide clinopathologic spectrum ranging from the classic patch-plaque MF to rare forms such as syringotropic MF.1 Syringolymphoid hyperplasia with alopecia, now recognized to be a premalignant form of syringotropic MF, was first described by Sarkany2 in 1969. When the cases of syringolymphoid hyperplasia with alopecia and syringotropic MF described in the literature are counted, the present case brings the total to 18 (13 men and 5 women).3
Because so few cases have been reported, it is difficult to characterize the . . . [Full Text of this Article]
