Lipoma Arborescens: A Rare Cause of Synovial Mass of the Knee at Pediatric Age with 10 Year Follow-up
Abstract
Lipoma arborescens (LA) is a benign lesion that occurs in the synovial joints and consists of villous lipomatous proliferation of mature fat cells in the
subsynovial tissue, often involving the knee joint. In addition to the knee joint, shoulder, elbow, and hip joint involvements have also been reported
in the literature. The most common site of involvement in the knee joint is the suprapatellar pouch. Patients usually present with painless joint range
of motion and swelling. Laboratory parameters are within normal limits. LA can be divided into two subtypes as primary and secondary according to
the age of the patient or the underlying rheumatological diseases. The primary type is mostly seen in pediatric patients and there is no underlying
chronic inflammation. In the secondary type, there is underlying chronic inflammation or trauma. In this case study, we described the operation
process and 10-year follow-up of an 8-year-old pediatric patient who applied to our clinic with knee swelling.
