Follicular mycosis fungoides is a rare variant of cutaneout T-cell lymphoma. We report a patient with thin plaques of mycosis fungoides studded with follicular papules. Histologically, these lesions were composed of dense infiltrates of lymphocytes within and around follicular epithelium (“folliculotropism”). This case indicates that follicular mycosis fungoides is a distinct clinicopathologic entity. It is different from follicular mucinosis associated with mycosis fungoides. Conceptually, the relationship between follicular mycosis fungoides and ordinary mycosis fungoides is analogous to the relationship of lichen planopilaris to ordinary lichen planus.
