a chronic or rapidly progressive form of cutaneous T-cell lymphoma; its name arose from the erroneous belief that it was of fungal origin. It may evolve into generalized lymphoma with a tendency for nodal, hematogenous, and visceral involvement. Its course has three successive stages: the premycotic stage, associated with intensely pruritic erythematous, eczematous, or psoriasiform eruptions; the mycotic stage, or stage of infiltrated plaques, characterized by the presence of abnormal lymphocytes called Sйzary cells; and the tumor stage, characterized by mushroomlike tumors that often ulcerate. In a variant type of tumor stage called mycosis fungoides d'emblйe, the tumors may develop without preceding lesions or prodromal symptoms. Called also granuloma fungoides.
Mycosis fungoides, with ulcerated plaques and tumors.
