Lichen planopilaris: Clinical and pathologic study of forty-five patients

Lichen Planopilaris is a Common Scarring Alopecia among Iraqi Population

“…Scarring alopecia of the scalp can be associated with other regional involvements as the present work showed that 26.8% of patients had extracranial involvement which was in agreement with many published reports [7,8].

Primary Lymphocytic Cicatricial Alopecia: A Retrospective Analysis of 36 Patients

“…In our study, supporting this knowledge, more than a half of the LPP patients (n=14, 53.8%) were between 40 and 60 years of age.

Frontal Fibrosing Alopecia

“…First of all, FFA influences predominantly females: in two tremendous circumstances sequence, male to feminine (M:F) ratio ranged from 1:289 to 1:31, whereas in LPP, M:F has been calculable at between 1:1.8 to 1:49 [16]. Lichen planus moving alternative websites (cutaneous, nail, mucosal) is seen additional usually in association with LPP (28-50%) [17,18] than with FFA (1.6-9.9%) [3,9,15] lack of facial and hair concomitant with LPP is suggested in 7-10% ( Figure 1) [16,18]. In FFA, lack of eyebrows has been said in round 80% of cases [2,4,9,15] and may just every now and then precede loss of hairline.…”
