- : A type of non-Hodgkin's lymphoma that first appears on the skin. Also called cutaneous T-cell lymphoma.
* * *mycosis fun·goi·des -fəŋ-'gȯid-.ēz n a form of lymphoma characterized by a chronic patchy red scaly irregular and often eczematous dermatitis that progresses over a period of years to form elevated plaques and then tumors
* * *a disease that is a variety of reticulosis confined to the skin, with plaques and later nodules infiltrated with T-lymphocytes. It progresses very slowly and can be treated initially with topical corticosteroids, later with PUVA and electron-beam therapy; chemotherapy is not helpful.
* * *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 SÐ¹zary cells; and the tumor stage, characterized by mushroomlike tumors that often ulcerate. In a variant type of tumor stage called mycosis fungoides d'emblÐ¹e, the tumors may develop without preceding lesions or prodromal symptoms. Called also granuloma fungoides.
Mycosis fungoides, with ulcerated plaques and tumors.
