title: Multiple oral petechiae and ecchymoses in a patient with osteoarthritis.
abstract: Ibuprofen is a frequently used medication, and possible drug reactions should be familiar to the clinician. Because oral manifestations of thrombocytopenia are often the initial finding and possibly represent the only clinical evidence of this disease, the dentist should be able to recognize the significance of these lesions and refer the patient for appropriate evaluation and therapy.
