Lymphology Association of North America (LANA) Practice Exam

What is the usual outcome if a seroma is left untreated?

1. It completely resolves without any complications.

2. It forms abscesses requiring surgical intervention.

3. It can leave behind scar tissue even if it resolves.

4. It causes systemic infection and requires immediate treatment.

The correct answer is: It can leave behind scar tissue even if it resolves.

When a seroma is left untreated, it can indeed lead to the formation of scar tissue even if the seroma itself eventually resolves. A seroma is a collection of fluid that can accumulate in a space in the body, typically after surgery or injury. While some seromas may resolve on their own, they can also affect the surrounding tissues, leading to fibrosis or scar tissue formation as the body attempts to heal the area. This scarring can potentially cause long-term issues with mobility or function and may complicate future medical treatments. In contrast to the correct answer, a seroma does not necessarily cause systemic infection immediately or always require surgical intervention. Systemic infection typically arises from other complications or conditions rather than from a seroma itself. It can also be managed conservatively in many cases, which differentiates it from conditions that demand urgent intervention. Thus, while it is beneficial to monitor for possible complications, scar tissue formation is a known consequence that underscores the importance of understanding seromas in a clinical setting.
