Follicular Mycosis Fungoides

ABSTRACT

We report a case of mycosis fungoides with small follicular papules and plaques on the trunk. Histopathological findings showed lymphocytic infiltration within and around the follicular epithelium and Pautrier's microabscess in the epidermis. Immunohistochemical studies showed atypical T lymphocytes infiltrating the follicles and electron microscopic examination revealed the presence of lymphocytes with large convoluted nuclei around the follicles. These findings suggest that the follicular lesions were specific for a special variant of mycosis fungoides.
