Osteochondromas may present in form of multiple hereditary exostosis or solitary osteochondroma. They are derived from aberrant cartilage from the perichondral ring and are benign chondrogenic lesions. Typical presenting age between 10 years to 30 years. They develop as a painless mass and appear on the bone's surface. Osteochondromas frequently occur at the points where tendons insert; the knee (proximal tibia, distal femur), proximal femur, and proximal humerus are common sites. Typically, the patient complains of deformity and swelling or are asymptomatic. They may appear as a pedunculated mass or as a sessile mass. This typically appears as mushroom shaped. It predominantly impacts enchondral ossification bones, occasionally affecting intramembranous ossification bones. We hereby reported a peculiar instance of osteochondroma of pedunculated type developing at a rare site –surface of ilium bone. Keywords Osteochondroma, Pelvis, Incidental, Benign bone tumour
