Abstract
Background: Alopecia areata (AA) is a common non scarring type of hair loss that affects 2% of the general population with unpredictable course. Aim: Histopathological comparing of perifollicular lymphocytic infiltrate in alopecia areata in both longitudinal and transverse sections and its relation to hair pull test. Methods: The study was conducted on 18 AA patients attending the dermatology outpatient clinic, Minia university hospitals from September 2022 to December 2022. Three millimeters punch biopsy was taken from the edge of the lesion in each patient and was processed routinely for longitudinal sections and was stained with hematoxylin and eosin stain then re-embedded and transverse sectioning was performed. Perifollicular mononuclear inflammatory infiltrate was evaluated either significant or not in each case and in each follicle. Result: Significant higher numbers of the terminal hair follicles with significant existence of perifollicular infiltrate were found in transverse sections when compared to longitudinal sections and that immune infiltrates positively correlated to the positive hair pull test.
