Alopecia areata (AA) is a T-cell-mediated autoimmune disease resulting in partial or total noncica-Tricial hair loss. HLA class II antigens are the most important markers that constitute genetic predis-position to AA. Various life events and intense psychological stress may play an important role in triggering AA attacks. We report an unusual case series of 4 family members who had simultaneously occurring active AA lesions. Our aim was to evaluate the clinical and psychiatric features of 4 cases of active AA lesions occurring simultaneously in a family and determine HLA alleles. The clinical and psychological features of all patients were examined. HLA antigen DNA typing was performed by polymerase chain reaction with sequence-specific primers. All patients had typical AA lesions over the scalp and/or beard area. Psychological examinations revealed obsessive-compulsive personality disorder in the proband's parents as well as anxiety and lack of self-confidence in both the proband and his sister. HLA antigen types were not commonly shared with family members. These findings suggest that AA presenting concurrently in members of the same family was not associated with genetic predisposition. Shared psychological disorders and stressful life events might be the major key points in the concurrent presentation of these familial AA cases and development of resistance against treatments.
