<p>Angiolipoma is a benign tumor that shows a mixture of adipose tissue and hemangioma-like lesion histologically. It frequently occurs in the trunk and limbs, and it is very rare in the lip. We report a case of angiolipoma of the upper lip. The patient was a 28-year-old woman who was referred to our hospital because of a mass in the right upper lip. A painless elastic-soft tumor was found under the mucosa of the right upper lip. The skin and mucosa just above the swelling was normal. MRI showed an unclearly demarcated lesion measuring 13 × 11 × 5 mm in the right upper lip with a mixed pattern of high and low intensity on T1- and T2-weighted images. An incisional biopsy was performed under local anesthesia, and the histopathological diagnosis was angiolipoma. Based on this diagnosis, the tumor was resected under general anesthesia. Immunohistochemical examination revealed CD31, CD34, α-SMA and VEGF positive cells in the tumor. There has been no recurrence one year after surgery.</p>

<p>Ectopic impacted teeth are considered to be caused by congenital malposition of tooth germs, increased internal pressure from cysts, tumor growth, periodontal ligament traction, and rupture of the gubernacular cord. It often progresses asymptomatic, but has been reported to cause pain and infection. Here, we report a case of ectopic impacted tooth in which the mandibular horizontal impacted wisdom tooth migrated to the vicinity of the mandibular notch over 9 years.</p><p> A 42-year-old woman visited our department with the chief complaint of pain in the left mandible. Upon comparison with past radiographs, the left impacted mandibular wisdom tooth was found to have migrated to the mandibular notch over 9 years. We performed an ectopic impacted wisdom tooth extraction to improve the</p><p>pain.</p><p> Fragile soft tissue was found forward the tooth. Histopathological specimens showed no epithelial structure and numerous plasma cell infiltrates. Immunohistochemical staining was negative for cytokeratin. The cause of the migration was considered to be the gubernacular cord thickened by inflammation. After the operation, the pain disappeared, no relapse was observed, and the patient has shown good progress.</p>

<p>Oxalosis is a rare disorder that deposits calcium oxalate in many organs of the body. We report a case of oxalosis with resorption of alveolar bone and tooth roots. The patient was a 60-year-old man who was given a diagnosis of oxalosis in another hospital and was referred to our hospital because of alveolar bone resorption in the right molar region of the mandible. Clinical and imaging examinations revealed resorption of alveolar bone and many teeth roots. Based on the results of histopathological examination, we attributed the resorption of alveolar bone and tooth roots to deposition of calcium oxalate. With time, resorption of the alveolar bone and tooth roots progressed.</p>

<p>Tumor-induced osteomalacia (TIO) is a rare disease associated with bone pain, walk disturbance accompanied by muscular atrophy of limbs, and malnutrition. To our knowledge, only 63 cases of TIO due to maxillofacial tumor have been reported. It is already known that the causative factor, FGF-23, is produced by tumors, resulting in TIO.</p><p> We describe our experience with a 57-year-old woman who had swelling in the palate and walk disturbance accompanied by severe lower limb pain. Hypophosphatemia and hypocalcemia were detected on blood tests. The histopathological diagnosis of the maxillary granuloma was giant cell reparative granuloma, and partial resection of the maxilla was performed given the possibility of TIO. In the 3 weeks after surgery, pain in the lower extremity and walk disturbance improved markedly. Currently, there is no recurrence as of 3 years after surgery, and the course is good.</p>
