This report describes a case of osteonecrosis of the jaw developing after a routine dental extraction in a patient being treated with dasatinib, a tyrosine kinase inhibitor, for chronic myelogenous leukemia. As the role of tyrosine kinase inhibitors in cancer treatment expands, patterns of debilitating complications involving the osseous structures of the oral cavity have begun to emerge, and many long-term side effects of this promising therapy remain unknown. To limit the occurrence of known complications, health care providers and patients must be aware of the potential for serious complications of dasatinib, and appropriate protocols should be in place before administration of this medication.
