A Case of Hypopigmented Mycosis Fungoides / 대한피부과학회지

ABSTRACT

Hypopigmented mycosis fungoides is a variant of mycosis fungoides. It occurs commonly in younger people and affects those with dark skin. This condition is easily misdiagnosed as vitiligo, postinflammatory hypopigmentation due to its non-specific clinical manifestation. We report a case of hypopigmented mycosis fungoides on both thighs and buttocks in a 44-year-male patient. Histopathologic findings showed Pautrier microabscesses and epidermotropism of atypical lymphocytes in the epidermis. CD8 immunohistochemical staining was positive. After narrow band UVB therapy, the lesions were completely repigmented. There was no evidence of recurrence of lesions after 5 months.
