Naevolipoma is a medical term used to describe a rare benign tumor that typically develops within a person's fatty tissue. Also known as hibernoma, it is generally characterized by the presence of both mature adipose cells (fat cells) and brown adipose cells (specialized fat cells responsible for heat production in the body).
This type of tumor usually occurs sporadically and has no clear cause or identifiable risk factors. It is often found in deep soft tissues, such as in the abdominal cavity, thigh, axilla, or retroperitoneum. Naevolipomas are typically painless and slow-growing, and they commonly present as soft, encapsulated masses.
In most cases, diagnosis of a naevolipoma is confirmed through imaging techniques, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. These imaging tests can help visualize the size, location, and nature of the tumor.
Treatment for naevolipoma is usually surgical removal. However, due to the tumor's proximity to vital structures and potential infiltrative growth, complete removal may not always be feasible. In such instances, close monitoring and periodic imaging are recommended to assess tumor behavior and prevent potential complications.
While naevolipomas are generally considered benign, they possess the potential to grow locally and might, in rare cases, undergo malignant transformation. Therefore, regular medical follow-up and evaluation are typically suggested to monitor any possible changes in the tumor's nature or behavior.
