Abstract

Background: Lichen planopilaris is a frequent presentation of primary cicatricial alopecia. Scalp distribution characterizes the main clinical presentations: classic lichen planopilaris, frontal fibrosing alopecia and Graham-Little Piccardi-Lassueur Syndrome (GLPLS).

Objective: Description of the clinical, dermoscopic and histopathological findings of Lichen planopilaris in public and private practices.

Method: A retrospective observational study was performed by reviewing medical records of patients with lichen planopilaris.

Results: Eighty patients were included, 73 (91,25%) were female. Prototype II was seen in 53 (66,25%) patients. Classic lichen planopilaris was seen in 62,5% of the cases. Frontal fibrosing alopecia was seen in 31% of the patients and only one patient presented Graham-Little Piccardi-Lassueur Syndrome (GLPLS). Scalp lesions were scattered throughout the scalp in 47 (58,75%) of the patients, while 24 (30%) presented mainly central scalp lesions, 29 (36,25%) presented marginal lesions and only 4 (5%) patents had vertex lesions.

Conclusions: Clinical presentation of Lichen planopilaris varies. To recognize the heterogeneity of the clinical appearance in lichen planopilaris is important for differential diagnosis.
