Abstract: A 27-year-old man presented with a 3-year history of persistent asymptomatic papules on the left chest and axirlary fossa. Multiple skin biopsies were performed and histopathology revealed mild acanthosis, extension of the dermal papilla, lichenoid lymphoid infiltrates in upper dermis. Some lymphoid cells migrated into the epidermis and formed Pautrier's microabscesses. Immunohistochemistry revealed that the infiltrating cells were positive for LCA, CD45RO, CD3, CD4 and CD8 (scattered), but negative for CD68 or CD30. Cutaneous laser confocal microscopy showed the shadow of scattered, oval or round, slightly refractive cells measuring 4-8 pm in diameter. A diagnosis of papular mycosis fungoides was made. The papules were softened with the lightening of lesional color after treatment with narrow-band ultraviolet B, topical fluticasone propionate cream and isotretinoin gel.
