Frontal Fibrosing Alopecia: A Retrospective Study of 75 Patients

Frontal fibrosing alopecia is an increasingly common form of scarring alopecia. The aim of this study was to describe the demographic and clinical characteristics of patients with FFA seen at the trichology unit of a medium-sized regional hospital and to report on treatments used.

We reviewed the medical records of all patients with FFA seen at the trichology unit of Hospital Universitario Infanta Sofía in Madrid, Spain between May 2016 and May 2018. We analyzed associations between disease severity, clinical patterns, need for oral medications, and other characteristics.

Seventy-five patients (73 women and 2 men) were studied. Diagnosis was clinical in most cases and 13 cases (17.3%) were confirmed histologically. Median (interquartile range) age at reported onset of symptoms was 61 (12) years. Involvement of the eyebrows was recorded in 70 patients (93.3%) and signs of oral and genital lichen planus in 7 (9.6%). Eleven patients (14.7%) had hypothyroidism and 15 (20.0%) had signs of rosacea. Only 5 of the patients who presented a linear pattern (21.7%) had severe hairline recession. Patients with unstable and/or symptomatic disease (n=24) were treated with oral medications (5-alpha reductase inhibitors, hydroxychloroquine, corticosteroids, and isotretinoin) or intralesional corticosteroids. Eighteen patients (75.0%) achieved disease stability. Ten of the 15 patients with signs of rosacea and 10 of those with facial papules required systemic treatment.

Most of the patients in this series of FFA were postmenopausal women. The prevalence of oral and genital lichen planus was higher than that observed in the general population. Patients with a linear pattern had less severe disease. Facial papules were more common in younger patients and both facial papules and rosacea were associated with a greater need for oral treatment.
