title: Osteolysis of the pubic bone simulating malignancy. A case report and review of literature.
abstract: A 78-year-old white female presented with groin pain of 3 months' duration. Radiographs revealed an osteolytic lesion in the pubic bone, simulating a malignancy or infection. A closed needle biopsy was performed and pathological findings were consistent with post-traumatic osteolysis, showing avascular necrotic tissues. A review of the literature found 16 previous cases presenting with groin pain and a radiographic lesion in the pubic bone that appeared malignant. All of the patients reported in the literature were postmenopausal women most with a recent history of trauma or increased physical activity. All of the lesions were benign and, when treated conservatively, usually resolved within 6 months.
