A Case of Poikilodermatous Mycosis Fungoides / 대한피부과학회지

ABSTRACT

We describe herein a sui generis case of poikilodermatous type of mycosis fungoides in a 33-year-old male. The lesions were peculiarly manifested by variegated changes such as hyper- and hypopigmented patches of varying size over the generalized area for about 5 years. Dry, scaly patches studded with violaceous-colored lichen planus-like plaques were on the left thigh and knee. Peripheral lymph nodes were nonpalpable. Biopsy specimens revealed epidermotrophism and Pautrier's microabscess being focal collection of large mononuclear cells with sight hyperchromatic cells in the epidermis. The infiltrating cells on the immunohistochemical staining were LCA and CD3 positive, but negative for CD20 in the epidermis and dermis.
