Mycosis fungoides palmaris et plantaris

Background:

Mycosis fungoides primarily localized to the palms and soles is rare and has been previously reported as cutaneous lymphoma in four patients or as Woringer-Kolopp disease in eight patients.

Observations:

Four patients were initially diagnosed and treated unsuccessfully for various palmoplantar dermatitides until histopathologic findings revealed mycosis fungoides. Each case exhibited a clonal rearrangement of T-cell receptor gamma genes and immunohistochemical studies consonant with mycosis fungoides. All patients had limited skin involvement without evidence of extracutaneous involvement.

Conclusions:

Mycosis fungoides palmaris et plantaris is an uncommon expression of mycosis fungoides that manifests primarily on the palms and soles and clinically may mimic various inflammatory palmoplantar dermatoses. A biopsy is recommended in the evaluation of recalcitrant palmoplantar dermatoses. (Arch Dermatol. 1995;131:1052-1056)
