Annular Alopecia Areata: Report of Two Cases
A 27-year-old male patient presented with the chief complaints of asymptomatic loss of hair from the scalp for the past 3 months. The hair loss started as a small patch and gradually increased in size assuming an annular pattern. There was no history of similar illness in family, no history of drug intake and no history suggestive of systemic illness. On examination, a well-defined area of non-scarring alopecia in an annular pattern was present at the occipital region of the scalp []. KOH examination did not reveal any fungal hyphae. Histopathological examination of a tissue taken from the affected area confirmed the diagnosis of AA. The patient improved markedly in 5 months with the intralesional triamcolone acetonide injections (5 mg/ml) every 4 weeks.
