Introduction: Lipoma arborescens presents a rare cause of chronic, slow-growing lesion which is characterized by proliferation of the synovium, with replacement of the subsynovial tissue by mature fat cells. It is most commonly observed in the knee joint, however other joints involvement have also been seen. Herein, we describe the exceptional case of bilateral Lipoma arborescens of the knees in a patient with pachydermoperiostosis (primary Hypertrophic osteoarthropathy).

Case Presentation: We report the case of a 26-year-old male presenting with swelling and joint effusion of right and left knees. The diagnosis of bilateral lipoma arborescens of the knees was considered, based on Magnetic resonance imaging (MRI) and histological findings. He was also diagnosed with complete primary form of pachydermoperiostosis according to physical examination, and investigation (thickening of the skin, peculiar cutis vertices gyrate, hyperhidrosis, clubbing and periosteal reaction in bones). The patient was treated by an open synovectomy associated with colchicine and oral paracetamol with a good response.

Conclusion: Lipoma arborescens is a rare entity. Bilateral involvement of the knees is rare and its association with pachydermoperiostosis is extremely rare. MRI is the best imaging examination. Surgical treatment by synovectomy offers excellent outcomes.
