Case Report of Hypopigmented Mycosis Fungoides in a Child




Child, cutaneous T-cell lymphoma, hypopigmented mycosis fungoides


Mycosis fungoides (MF) is a cutaneous T-cell lymphoma, which some variants manifest as generalized hypopigmentation of non-sun exposed area of skin. Classic MF presents with the typical evolution stages of patches, plaques and tumors. MF is common in older adults but rarely occurs in children.

We reported a case of 9-year-old Thai boy patient who presented with generalized hypopigmented patches and macules on face, trunk and both extremities. The histopathology was compatible with MF. There was no systemic involvement. The TNM staging was stage IB. The patient was treated with 28 sessions of narrowband UVB (NB-UVB) phototherapy with complete response, however recurrence occurred after 7 months of NB-UVB discontinuation.
