ABSTRACT

Observation:

Mycosis fungoides is a type of T cell lymphomas, that primary shows in skin. It was first described by Albert in 1806. The cause is unknown, but there have been theories relating to viral, chemical and genetic factor that affects the immune system by causing stimulation of the lymphocytes during a long-period. Since the abnormal T cells are gathered together in the skin, the skin shows many signs and can be misdiagnosed for symptoms such as: psoriasis, urticaria, and mycotic infections or especially atopic dermatitis. This fact can lead to a delay of the diagnosis. The diagnosis is set up by performing a biopsy and imunohistochimie, but in some cases the biopsy does not solve the real problem. The treatment is based on the specific stage in which the disease is currently. Topical chemotherapy, topical retinoid and corticosteroids, PUVA therapy, fusion proteins, extra corporal, photopheresis and systemic chemotherapy are some of the options. In this paper, we present the case of a 74-year-old man presented with a one year history of the pruritic dermatitis treated by the dermatologist.
