Mycosis fungoides with unusual vitiligo-like presentation.

Mycosis fungoides (MF), the commonest variant of primary cutaneous T cell lymphoma (CTCL), is relatively uncommon among the Asians. Hypopigmented mycosis fungoides is a rare variant usually observed in dark-skinned individuals, especially children. Hypopigmented MF usually responds well to therapy, particularly to PUVA, and has a comparatively benign course. Mycosis fungoides in a 16-year-old boy, with extensive asymptomatic hypopigmented lesions developing gradually all over the body over eight years and vitiligo-like skin lesions developing for seven years, with no systemic features, is presented for its unusual clinical features and conspicuous histopathological findings of prominent epidermotropism. The case showed fairly good response to PUVASOL therapy.
