co-existence of non-ossifying fibroma and osteoid osteoma in one tibia: a case report

Presentation of two independent tumors in one case is rare; coincidence of two different bone tumors in a single bone and limb is extremely rare. here we reported on a male adolescent case with co-existence of nof and an osteoid osteoma in ipsilateral tibia which was presented with left leg pain and swelling; both tumoral lesions were excised and the patient became symptom free. this case study highlights the importance of careful clinical and radiological investigation for more pathologies in spite of finding a single tumor; and encourages further research on the possible genetic links between these two kinds of tumors.
