Synchronous gnathic osteosarcoma and B-cell lymphoblastic lymphoma/leukemia: A rare case presentation.

Multiple primary malignancies are a well-recognized entity, with increased recognition and detection alongside development of hybrid imagining. We present a rare case of a 16-year-old male with gnathic osteosarcoma and incidental finding of a second silent synchronous B-cell lymphoblastic lymphoma/leukemia in the lower limb. Treated successfully by chemotherapy, radiotherapy, and surgery.

Exercise-induced thoracic outlet syndrome and concomitant osteomyelitis in cervical rib with a possible familial origin: A case report.

Cervical ribs are rare and usually asymptomatic. Occasionally, they can cause nerve impingements and compressive symptoms. In cervical ribs, osteomyelitis secondary to trauma is unheard of. We report such a case made more interesting by the familial presence of bilateral cervical ribs in two generations, indicating a familial origin.
