Case Report: In this study, we are herewith reporting an unusual case of pubic tubercle osteochondroma, which is solitary and pedunculated in a 37-year-old woman. She has had the swelling for the past 15 years, which was asymptomatic except for mild hydroureteronephrosis, which was an incidental diagnosis; however, we managed the patient with surgical excision of the tumor with elaborate preoperative radiological imaging using both X-ray and computed tomography (CT) scan. Histopathological examination confirmed the diagnosis of osteochondroma. Conclusion: Asymptomatic pelvic osteochondroma should be considered in patients with incidental swelling in the groin region, especially women who may be reluctant to seek medical attention due to social stigma. https://jost.tums.ac.ir/index.php/jost/article/view/487 https://jost.tums.ac.ir/index.php/jost/article/download/487/350
