The usefulness of trichoscopy in the diagnosing of fibrosing alopecia in pattern distribution

This report emphasizes the importance of trichoscopy in diagnosing fibrosing alopecia in pattern distribution (FAPD), particularly in differentiating it from female pattern hair loss (FPHL). In a case study of a 49-year-old postmenopausal woman with hair thinning and scalp symptoms, trichoscopy revealed specific features such as areas lacking follicular orifices and hair shaft thickness heterogeneity, leading to a diagnosis of FAPD. Treatment with hydroxychloroquine and finasteride halted disease progression and alleviated symptoms over a 1-year follow-up. Accurate diagnosis is crucial due to the distinct trichoscopic features and differing treatment approaches between FAPD and FPHL.
