Hypo-pigmented mycosis fungoides is a rare malignancy in pediatrics.

Hypopigmented mycosis fungoides (HMF) is an uncommon form of cutaneous T-cell lymphoma. It can be seen in children and is usually mistaken for eczema, vitiligo, or progressive macular hypomelanosis, clinically and histopathologically. We present a boy with HMF confirmed by histopathology. The patient had a course with slow clinical progression without Sezary syndrome.
