Aseptic and Alopecic Nodule of the Scalp in a Young Female With Alopecia Areata.

Aseptic and alopecic nodules of the scalp (AANS) is a rare, likely underrecognized, nonscarring alopecia characterized by one or more alopecic nodules without evidence of microbial infection. AANS has a favorable prognosis and often responds well to treatments such as doxycycline, intralesional steroids, or drainage. We present a case of AANS in a young female with a history of biopsy-proven alopecia areata that achieved full resolution without recurrence with intralesional steroids. Recognition of this rare condition, including in the setting of other established alopecia diagnoses, may avoid a missed diagnosis as well as unnecessary surgery.
