Alopecia mucinosa

    Clinical Features:

    • Erythematous plaques devoid of hair, most commonly on the head and neck
    • Most often self-limiting
    • 30% of cases are associated with a lymphoproliferative disorder, especially a cutaneous T-cell lymphoma.

    Histologic Features:

    • Follicular mucinosis (deposition of mucin within the follicular epithelium) beginning in the infundibulum and eventually involving the entire follicle with formation of mucin-filled cystic spaces
    • Perifollicular infiltration of lymphocytes with some eosinophils
