Mycosis fungoides evolving to myelomonocytic leukemia.

Acute myelomonocytic leukemia, a type of leukemic conversion that may be a manifestation of mycosis fungoides, developed in two patients with fairly typical courses of mycosis fungoides. The cases of five other patients with myelogenous leukemia as the terminal event of mycosis fungoides have been reported in the literature. A relationship to therapy could not be established, although all patients had had irradiation or chemotherapy or both.
