“…In case of doubt, a skin biopsy for histopathological investigation should be done in order to further evaluate the nature of the hair loss. The observed alopecia may prove to be a scarring alopecia as a symptom of folliculotropic mycosis fungoides (FMF), a rare, difficult to diagnose [ 20 , 21 ], and potentially aggressive subtype of a cutaneous T-cell lymphoma (CTCL ). For this unique clinical finding we propose the term alopecia lymphomatica to recognize this rare but potentially dangerous form of scarring alopecia which should be clearly distinguished from other types of scarring hair loss [ 22 ] .…”

Folliculotropic mycosis fungoides (FMF) is a particular subtype of mycosis fungoides (MF), characterized by an infiltration of neoplastic CD4? T cells in the epidermis which can spread to all follicular structures, sebaceous glands, sweat glands and hair follicles. Clinically, FMF can exhibit various cutaneous symptoms. However, these symptoms often occur on the scalp, face and neck, which are rarely affected by conventional MF. We report cicatricial alopecia in a patient with FMF as alopecia lymphomatica. This peculiar symptom should be kept in mind as a critical differential diagnosis of scarring alopecia, leading to further investigation. Thus, an early diagnosis of FMF may be obtained.
