    TLDR Benign follicular mucinosis involves immune cells attacking hair follicles.
    The study on two patients with benign follicular mucinosis (FM) revealed degenerative changes in the follicular outer root sheath and sebaceous gland epithelium, accompanied by benign inflammatory cell infiltration. Using light and electron microscopy, researchers observed associations between disattached keratinocytes, macrophages, and Langerhans cells. Immunofluorescence detected complement (C3) and fibrinogen/fibrin in degenerated areas, while immunoperoxidase studies indicated increased T cells, macrophages, and Langerhans cells in the affected follicular epithelium. These findings suggested that cell-mediated immune mechanisms might have contributed to the pathogenesis of FM.
