Hematomas, pseudocysts, and seromas are all part of the differential diagnosis of auricular swellings. Seromas are benign collections of serous fluid that have a tendency to recur. The fluid accumulates in the space between the dermis and perichondrium of the ear. We describe what we believe is the first case of spontaneous bilateral auricular seromas to be reported in the literature. One of the seromas resolved in 4 weeks without treatment, and the other resolved with incision and drainage. It is important for physicians to be aware of auricular seromas when considering the differential diagnosis of an auricular swelling, and to understand the various treatment options.
