A Case of Follicular Mycosis Fungoides With Follicular MucinosisA Rare Association

摘要

Follicular mycosis fungoides (FMF) is a rare cutaneous T cell lymphoma characterized by an atypical lymphoid infiltrate spreading within and around hair follicles without epidermotropism or follicular mucin deposits. Its occasional presentation with minimal epidermal involvement and/or follicular mucinosis suggests the need for uniform histologic criteria. We describe a new case of FMF associated with follicular mucinosis and discuss its morphologic spectrum of presentation.
