Abstract:
|
BACKGROUND:
Alopecia areata incognita is a variety of alopecia areata characterized by acute diffuse shedding of telogen hairs without typical patches.
OBJECTIVE:
We sought to report the clinical, pathological, and dermoscopic features of alopecia areata incognita.
METHODS:
Seventy patients with alopecia areata incognita were evaluated clinically and with videodermoscopy during the period of 2002 to 2006. Pathology was performed in 50 patients.
RESULTS:
The presence of numerous, diffuse, round or polycyclic yellow dots, different in size and uniform in color and distribution, was a typical dermoscopic feature in all patients. Short regrowing hairs were also present. The dermoscopic findings were correlated and supported by the histologic features of the scalp specimens. LIMITATIONS: Scalp biopsy was performed only in 50 patients.
CONCLUSION:
Videodermoscopy is a first step before performing a biopsy. It can help the clinician to find the right place to take the sample, but can also avoid unnecessary biopsies.
