原始语种摘要: Yellow dots are the most useful dermoscopic criterion in the clinical diagnosis of alopecia areata and correspond histopathologically with dilated follicular infundibula. They are found in about 95% of alopecia areata cases and help to differentiate alopecia areata from trichotillomania, telogen effluvium and from scarring alopecias. Histopathology of alopecia areata differs with disease activity and dermatopathologist, therefore, heavily depends on other diagnostic features. Objective of the study was to determine the frequency of dilated follicular infundibula, peribulbar lymphocytic infiltrate, inflammatory infiltrates of lymphocytes and eosinophils within fibrous streamers and a shift to catagen/telogen follicles in alopecia areata. Histopathologic features of 56 specimens of 33...
