History:

This 53-year-old man presented with scarring alopecia that was slowly progressive of 2 years duration. On examination, many cicatricial patches were found on the vertical area and sides of the scalp. At the periphery of these patches many violaceous follicular papules were seen. Lichen Planopilaris designates the folliculotropic variant of LP, which predominantly involves the scalp. Initially, there may be only follicular papules or perifollicular erythema; however, with progressive hair loss, irregularly shaped atrophic patches of scarring alopecia develop on the scalp.
