CD4 cells implicated in pathology of CCCA

Key clinical point: Langerhans cells in hair follicles have been found to sustain a CD4 cell-mediated inflammatory reaction that characterizes central centrifugal cicatricial alopecia (CCCA).

Major finding: Unlike many other forms of scarring alopecia, CCCA has a CD4-predominant lymphocytic inflammatory infiltrate.

Data Source: The study involved pathological examination of biopsy specimens of 18 black women with a known diagnosis of CCCA.

Disclosures: The authors did not list any disclosures. The funding source was listed as the Center for Scientific Review (Grant/Award).
