A Delayed Seroma of a Facial Full-Thickness Skin Graft Donor Site: A Case Report

Seromas are characterized as an accumulation of serous fluid beneath the skin, commonly occurring as a postoperative complication. Such formations can occur in dermatologic surgeries where the undermining and dissection of soft tissue create an empty cavity for fluid accumulation. When seromas develop, they usually do so at the wound closure site, within approximately a week after repair. In some cases, seromas have been shown to occur beyond the expected timeframe, coining the term "late seromas." In this context, we present a case of a postoperative seroma noted 21 days after harvesting a full-thickness skin graft from the donor site in the preauricular region.
