Background and Aim: Cicatricial alopecia refers to lesions that result in permanent and irreversible hair loss and are associated with destruction of hair follicles. In this alopecias the hair follicle is replaced with connective tissue. After remission of initial infection or inflammation, hair regrowth is unlikely. Methods: In this retrospective cross-sectional study, 222 patients with cicatricial alopecia, admitted to Farshchian Hospital, Hamadan, Iran were investigated. Hospital records of patients with cicatricial alopecia were reviewed, and their demographic as well as clinical data were extracted and entered into prepared data gathering forms. Results: One-hundred and ten patients (49.5%) had discoid lupus erythematosus, 71 patients (31.9%) had lichen planopilaris, 23 patients (10.4%) had pseudopelade of Brocq, 11 patients (4.9%) had keratosis pilaris spinulosa decalvans and 3 patients (1.3%) had central centrifugal cicatricial alopecia. Each of alopecia mucinosa and dissecting cellulitis/folliculitis were observed in 2 patients (0.9%). The correlation between of illness, extent of disease, gender, location, occupation, and clinical features of the disease were studied. Conclusion: Cicatricial alopecia usually results in irreversible hair loss, but early diagnosis and treatment can prevent the progression of the lesions and its complications. The diagnosis of this disease is possible with a clinicopathologic study.
