Folliculotropic mycosis fungoides is a rare and aggressive subtype of mycosis fungoides characterized by small to medium-sized malignant T-cells that typically infiltrate the hair follicle. It represents 4% of primary cutaneous lymphomas and less than 10% of patients with MF.



We report 2 cases of 80-year old female, who presented with a 3-year history of an erythematous plaque on the left infraorbital area and forehead, and the other with an 8-month history of multiple erythematous indurated plaques on the left cheek, left eyebrow and malar area. Clinical presentation, histopathology and immunohistochemistry findings revealed a diagnosis of folliculotropic mycosis fungoides.



Folliculotropic mycosis fungoides has distinct clinical and microscopic features. Evaluation of clinical, pathologic, and immunophenotypic findings are important to identify this rare form of cutaneous T-cell lymphoma.
