A seroma is usually painless, but mild discomfort may occur. A clear discharge may be present. In the rare case of secondary infection, a seroma may become tender and develop into an abscess requiring immediate medical attention. Other signs of infection include fever and a bloody, malodorous, or purulent discharge.
The most common types of surgeries that cause wound seromas are breast, abdominal wall, and reconstructive surgeries, particularly if skin flaps are created or if a foreign body, such as prosthetic mesh, is introduced.
