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.
毛囊性蕈样肉芽肿（FMF）是蕈样肉芽肿（MF）的一种特殊亚型，其特征是肿瘤性CD4 + T细胞浸润表皮，可扩散至所有毛囊结构、皮脂腺、汗腺和毛囊。临床上，FMF可表现出各种皮肤症状。然而，这些症状常发生于头皮、面部和颈部，而这些部位很少受到传统MF的影响。我们报告了一例FMF患者出现瘢痕性脱发，表现为淋巴性脱发。这种特殊症状应作为瘢痕性脱发的重要鉴别诊断予以考虑，以便进行进一步检查。因此，可实现FMF的早期诊断。
