In clinic, some anatomical abnormalities and primary non-odontogenic diseases of the jaw tend to appear around the apex. Low-density transmission images of bone destruction in X-ray films are easily confused with periapical diseases^[1]Not only can these diseases not be healed by endodontic treatment, but if they are not identified, they can easily cause misdiagnosis and bring unnecessary harm to patients. Three patients were admitted to the Department of Dentistry and Endodontics, School of Stomatology, China Medical University, and their X-ray films showed images similar to those of periapical disease.

Myelofibrosis is a myeloproliferative disease divided into two categories: primary and secondary. primary myelofibrosis (PMF) is a myeloproliferative tumor caused by unexplained hematopoietic stem cell abnormalities. Its lesions include proliferation of bone marrow megakaryocytes and granulocyte lines, fibrous tissue proliferation and extramedullary hematopoiesis, which often leads to anemia and hepatosplenomegaly. PMF mostly occurs in the elderly and is rare in children. Some scholars studied 642 patients with PMF and found that the average age of onset was 53 years old (14-85 years old)^[1]At present, there are only more than ten reports of PMF in children, only 3 cases involving imaging manifestations, and no reports involving the jaw. Jaw involvement in adult patients with PMF is also rarely reported. One case of PMF involving jaw and other bones in a child was admitted to our hospital, which is reported below.

Congenital hypoglossia (hypoglossia) is a rare midline dysplasia, which often manifests as small mouth fissure, small tongue, small jaw, intraoral adhesion, and sometimes may be accompanied by developmental malformations of limbs and viscera. Its incidence is 1/175 000^[1,2]。 A patient with congenital tongue hypoplasia with cystic-solid lesions of the floor of the mouth was admitted to the Stomatological Hospital affiliated to Zunyi Medical College, and the report is as follows.
