Seroma

Seromas are collections of serous fluid that usually occur as a complication of surgery, but can also be seen post-trauma. It is most commonly associated with post-breast surgery, where a potential space is left.

Seromas are distinct from a haematoma as it contains almost no red blood cells and from an abscess are they are sterile fluid collections.

Serous fluid can refer to any clear proteinaceous fluid in the body. It is named as it was identified as being secreted by serous glands such the parotid. It is similar to effusions that are found elsewhere.

Seroma formation is thought to occur as plasma from local hemorrhage and other serous fluid accumulates at the site of tissue removal or disruption from surgery or trauma. The fluid collects within scar tissue and can accumulate to a large size causing discomfort or can be unsightly.
