Alopecia areata (AA) is a relatively common hair disorder with several clinical patterns.1 We performed a retrospective study of 1604 cases of AA and analyzed the patterns of hair regrowth in each case. There were 13 cases of what appears to be a new pattern of regrowth, which we termed androgenetic (AGA)—like pattern.
Patients and Observations.
During an 18-year period (1975-1993), 1604 patients with AA were followed up to assess different types of AA: 842 patients were male and 762 were female; the age of onset ranged from 2 to 72 years. All patients were white and the rate of familial incidence was 21.3%.2 All patients were photographed at each visit. Immune system function was studied in all patients and hormonal analyses were performed in those with an AGA-like pattern. Patients were examined every 3 months during the first year and every 6 months thereafter. We identified 13 patients
