Poikilodermatous mycosis fungoides

Poikilodermatous mycosis fungoides is a rare form of cutaneous T-cell lymphoma that is characterized clinically by localized or diffuse patches, which consist of telangiectases, mottled hyper- and hypopigmentation, and atrophy. The immunophenotype of neoplastic cells is similar to that observed in classic mycosis fungoides. Therapeutic options used in poikilodermatous and classic mycosis fungoides include both skin-directed and systemic treatments. We present a case of poikilodermatous mycosis fungoides in a 53-year-old woman, who initially presented with erythroderma and who has failed multiple treatment modalities.
