Mycosis fungoides

Mycosis fungoides is the most common form of cutaneous T-cell lymphoma, a cancer of T-lymphocytes that generally affects the skin but can progress internally over time. It arises from abnormal T-lymphocytes proliferating in the skin outer layer for reasons that remain unclear, and most cases are not hereditary. The disease most often appears in people over 20, is more common in men, and typically advances through three stages, patches, plaques and tumors, with symptoms including rash, skin lesions and itching. Despite its name, it is not a fungal infection but a form of non-Hodgkin lymphoma, treated with approaches such as sunlight or ultraviolet light exposure, topical corticosteroids, chemotherapy and radiotherapy.
