Mycosis fungoides-like lesions associated with phenytoin therapy. 1985

R Wolf, and E Kahane, and M Sandbank

An 83-year-old woman developed generalized lymph node hyperplasia together with mycosis fungoides-like skin lesions 11 months after institution of anticonvulsant therapy with phenytoin. The clinicopathological changes disappeared completely three weeks after cessation of therapy. This circumstantial evidence together with the known data on the association of phenytoin with lymphoproliferative disorders suggest that it was the phenytoin that was responsible for the patient's condition. This case had features similar to those associated with the pseudo-mycosis fungoides syndrome except that the cutaneous lesions consisted of two localized erythematous plaques, with no generalized exfoliative erythrodermic dermatitis. Nonetheless, we believe that the use of the term pseudo-mycosis fungoides for this and similar cases would be appropriate.

UI	MeSH Term	Description	Entries
D006965	Hyperplasia	An increase in the number of cells in a tissue or organ without tumor formation. It differs from HYPERTROPHY, which is an increase in bulk without an increase in the number of cells.	Hyperplasias
D008198	Lymph Nodes	They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system.	Lymph Node,Node, Lymph,Nodes, Lymph
D009182	Mycosis Fungoides	A chronic, malignant T-cell lymphoma of the skin. In the late stages, the LYMPH NODES and viscera are affected.
D010672	Phenytoin	An anticonvulsant that is used to treat a wide variety of seizures. It is also an anti-arrhythmic and a muscle relaxant. The mechanism of therapeutic action is not clear, although several cellular actions have been described including effects on ion channels, active transport, and general membrane stabilization. The mechanism of its muscle relaxant effect appears to involve a reduction in the sensitivity of muscle spindles to stretch. Phenytoin has been proposed for several other therapeutic uses, but its use has been limited by its many adverse effects and interactions with other drugs.
