Alopecic and aseptic nodules of the scalp (AANS) is a relatively new and little-known entity, and thus may possibly be underdiagnosed. This condition was first described in Japan by Iwata et al., in 1992. This disease occurs mainly in young males and is characterized by the presence of aseptic nodular scalp lesions associated with nonscarring alopecia that may resolve within 3 months. Here, we are reporting a case of AANS with a chronic relapsing course. To the best of our knowledge, this is the first case of this rare entity that has been reported in Iraq. We are urged to report this case due to the following factors: a paucity of reports in the literature (to date, fewer than 90 cases have been reported worldwide), an uncanny resemblance to other entities - especially, dissecting cellulitis of the scalp and alopecia areata - and the unusual chronic relapsing course of the disease.
