Auricular seroma: Case report

Auricular seroma is an uncommon, non-inflammatory, and benign condition affecting the auricle. Synonyms for auricular seroma include auricular pseudocysts, cystic chondromalacia, endochondral pseudocyst, intracartilaginous cyst, and benign idiopathic cystic chondromalacia. While there is no known genetic predisposition, it exhibits a higher occurrence in Chinese and Caucasian males. The prevalence is greater in males than females and typically manifests unilaterally. The hypothesis proposing hormonal influences on the inflammatory process is suggested to explain the male predominance. In unilateral instances, the right ear is more frequently affected than the left ear. Bilateral seroma presence is documented in the pediatric population. Although seromas can manifest anywhere on the auricle, they commonly occur in the scaphoid fossa. Auricular seromas are characterized by the accumulation of sterile, viscous straw-yellow fluid without cells within the cartilage.
