Simultaneous occurrence of mycosis fungoides and Hodgkin disease: clinical and histologic correlations in three cases with ultrastructural studies in two.

We present three patients who manifested both Hodgkin disease and mycosis fungoides. Ages ranged from 39 to 66 and two were male. Skin lesions were present from 3 to 40 years before the diagnosis of Hodgkin disease. In all cases, mycosis fungoides was confirmed histologically by skin biopsy; the clinical course of the mycosis fungoides was indolent in all cases. Hodgkin disease was confirmed histologically in three, and confirmed by electron microscopy in two. All three patients responded to appropriate treatment for Hodgkin disease and are alive and well at the present time.
