Mycosis fungoides occurring at the site of previous herpes zoster eruption

Abstract

Numerous clinicopathological variants of mycosis fungoides have been described in the literature. Dermatomal or zosteriform mycosis fungoides is one reported variant but a clear aetiology has never been documented. We report a case of mycosis fungoides proved by biopsy and immunohistochemistry that developed in a 55-year-old man at the site of previous herpes zoster eruption. We also present a review of the relevant literature to add to the understanding of rare variants of mycosis fungoides and aid in the clinical recognition of zosteriform mycosis fungoides.
