There are few reports regarding auricular seroma, and the definition for it is unclear. Herein, we report 16 cases of auricular seroma. We found several common characteristics: (1) no obvious history of trauma, insect bite, or bruising, (2) accumulation of a small amount of rose-wine– or straw-colored serum in the hypodermis but above the perichondrium, determined by puncture aspiration, (3) most often located between the antihelix and concha, (4) no sign of marked inflammation or severe pain, and (5) disappearance without marked disfigurement. We advocate treating auricular seroma as an independent disease entity apart from other auricular swellings such as hematoma and pseudocyst.
