Acute myeloblastic leukemia (AML) is a highly fatal malignant bone marrow disease. Physicians, dentists and all other healthcare professionals should be aware of sinister oral signs and symptoms in order to early diagnosis and referral of patients. Here we report a case of AML who presented with oral ulcers. Ulcers developed after a parrot bite, which initially misled the physicians. Unfortunately our patient did not survive, but early diagnosis and prompt investigation and treatment can be life-saving in many other similar cases.
