    Abstract:
    BACKGROUND: Osteochondromas or exostoses are the most common benign tumors of the bones, which appear during the growth period. The involvement of lower extremities is common, particularly in metaphyseal structures of the femur and humerus and around the knee joint. However, the incidence of the development of the tumor at the proximal fibula is rare. The most common signs and symptoms of the disease are pain, pulsatile mass, limb swelling, neurologic sequelae, bursa formation with subsequent bursitis, and impairment of the developmental growth. Vascular complications are rare, yet osteochondromas can cause catastrophic arterial complications threatening the life of the patient if they occur and can include vessel perforation and thrombosis, arterial thromboembolic events, and pseudoaneurysm formation. METHODS: We report a case of a 24-year-old male patient presenting with tibioperoneal arterial trunk entrapment caused by a massive osteochondroma derived from the proximal fibula. A combined vascular-orthopedic approach was initiated with the excision of the tumor, in which the neurovascular structures (tibial nerve, popliteal artery and vein, anterior tibial artery, and tibioperoneal trunk) were carefully recognized and protected. RESULTS: The postoperative course of the patient was uneventful. CONCLUSIONS: High clinical suspicion of a vascular complication should be raised by physicians when investigating a young patient with a suspected osseous tumor in the popliteal fossa and symptomatology of concurrent peripheral arterial disease. Prompt surgical management is crucial for the salvage of the affected limb in cases of arterial involvement. Furthermore, quick surgical exposure of the mass and regular postoperative follow-up check minimizes the risk of irreparable impairments and tumor recurrence.
