Abstract BACKGROUND: The purpose of this study is to describe two new trichoscopic signs, "Eastern pancake sign" and "comedo-like structures", not previously reported to our knowledge and seen in 5 patients with alopecic and aseptic nodules of scalp (AANS). PATIENTS AND METHODS: We report on 5 patients presenting AANS. Demographic and ethnic characteristics, disease duration, clinical description, treatment and evolution were noted. Trichoscopy was performed for all patients. RESULTS: In all cases of NAAS, trichoscopy revealed 2 signs: "Eastern pancake sign" resulting in heterogeneous dilated follicular orifices without trichoscopic signs of alopecia areata, and "comedo-like structures" resembling comedones. DISCUSSION: To our knowledge, there have been no previous reports in the literature of the 2 new trichoscopic signs of AANS described herein: "Eastern pancake sign" and "comedo-like structures". The trichoscopic feature of comedo-like structures suggests the potential role of follicular occlusion in this disease. We consider that follicular occlusion may be a triggering factor in AANS.
