Fracture of the anterior iliac crest following monocortical bone graft harvest in bisphosphonate-related mandibular pathological fracture: a case report.

The anterior iliac crest is the most common donor site for autologous nonvascularized bone because of the great amount of bone available and easy access. Documented donor-site complications include arterial, nerve, or urethral injury; herniation; chronic donor-site pain; sacroiliac joint instability; pelvic fractures; gait disturbances; hematoma; infection; peritoneal perforation; cosmetic defects; and hip subluxation. We present the case of a pathologic fracture of the right anterior iliac crest during the immediate postoperative period in a patient with a bisphosphonate-related osteochemonecrosis with pathological fracture of mandibular body. The patient was managed with nonoperative treatment.

Oral primary angiosarcoma of the lower lip mucosa: report of a case in a 15-year-old boy.

BACKGROUND: Angiosarcomas are rare soft tissue malignant tumors with dismal prognosis. Head and neck involvement is uncommon (5%) and usually affects the scalp or facial skin. METHODS AND RESULTS: We present the case of an inferior lip mucosal low-grade angiosarcoma in a 15-year-old boy treated exclusively with surgery. One and a half years after treatment, the patient was free of signs of recurrence. Prompt and accurate diagnosis with adequate imaging modalities and multidisciplinary treatment are crucial for optimal management of these neoplasms. CONCLUSION: Lip mucosal involvement is exceptional with only a few cases described in the literature, all in patients older than 60 years To our knowledge, this is the youngest patient ever reported.
