Abstract

Background: In central centrifugal cicatricial alopecia (CCCA), a lymphocytic scarring alopecia that primarily affects black women, it has been postulated that there is a "pro-fibrotic" tendency and increased risk for systemic fibroproliferative disorders. Objective: To determine whether women with biopsy-proven CCCA have a greater likelihood of systemic fibroproliferative disorders (FPDs) of the lungs (interstitial lung disease), arteries (atherosclerosis of the aorta), liver (non-alcoholic steatohepatitis), kidney (end stage renal disease), or uterus (uterine leiomyoma). Methods: We conducted a retrospective matched cohort study evaluating 427 cases with biopsy-proven CCCA and 1281 age- and sex-matched controls. Results: Black women with biopsy-proven CCCA, were not more likely to have interstitial lung disease (ILD), atherosclerosis of the aorta, non-alcoholic steatohepatitis (NASH), end stage renal disease (ESRD), or uterine leiomyoma. Central centrifugal cicatricial alopecia was associated with a history of never smoking and higher body mass index. Conclusion: In this large cohort of biopsy-proven women with CCCA, there was no association with specific fibroproliferative disorders when compared with age and sex matched controls. Future longitudinal studies may help confirm these results.
