Mycosis Fungoides Palmaris et Plantaris

Abstract

We read with interest the recent article by Resnik et al 1 concerning mycosis fungoides palmaris et plantaris. They present 4 patients with recalcitrant palmoplantar dermatoses that subsequently proved to be mycosis fungoides on biopsy. Of the patients presented, the initial descriptions were of localized plaques, patches, callouses, blisters, or fissures. Herein we report an interesting variant of mycosis fungoides palmaris et plantaris with diffuse hyperkeratosis resembling keratoderma. A 53-year-old black man complained of progressive thickening and pruritus of the palms and soles over the preceding 12 months. Results of physical examination revealed diffuse thickening of the palms and soles with lichenification and hyperpigmentation. There was no fissuring and the dorsal surfaces and interdigital spaces were not involved. In addition, there were hyperpigmented plaques in the axillae that had been present for 3 months. Three 4-mm punch biopsy specimens were obtained, 2 from the palm and 1 from the right
