Iliac Blade Osteochondroma: A Rare Case Presentation and Review of Literature

Most common benign tumors in orthopedic outdoor clinics seem to be osteochondroma/exostosis which are around 20-50% of all benign bony lesions. Flat bones like iliac blade, scapula, ribs and clavicle which develop from intra-membranous ossification are rarely involved. A28 year old female from rural area presented to orthopedic outdoor clinic with pain and swelling around the inguinal region on right side for past 18 months and diagnosis was made after incisional biopsy. Iliac blade is a rare site for presentation and the patient had no neurovascular compression or mass effect on surrounding structures. Osteochondromas of flat bones are rarely encountered, therefore, proper diagnosis should be made and other differential diagnoses should be considered during evaluation of mass around the pelvic girdle.
