INTRODUCTION Clear cell neoplasms of the jaw are very infrequent and a review of the literature reports only isolated cases of metastatic renal clear cell carcinoma of the jaw. CASE PRESENTATION A 68-year-old man presented with an osteolytic lesion of the left hemimandible. The first diagnostic hypothesis was a third molar follicular cyst. Surgical treatment consisted of enucleating the lesio...

A 54-year-old male with partial denture underwent stereotactic radiosurgery with an infrared camera-guided system for a metastatic brain tumor arising from lung cancer. Although this method utilizes a biteplate mounted on the upper jaw to detect head movement, the patient only had four teeth in his upper jaw. In order to stabilize the biteplate, the maxillary denture was fixed to the biteplate ...

Introduction: Primary gastric lymphoma (PGL) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (IHC) and genetic analysis. Case Presentation: A 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise IHC and staging in another center. Inappropriate IHC after surgery showed diffuse large B-cell lymphom...

Background Hyperparathyroidism-Jaw Tumor (HPT-JT) syndrome is a rare genetic disorder bearing both a germline and a somatic CDC73 mutation (formerly known as HRPT2), which has been mapped to chromosome 1q25-q31. The association of jaw ossifying fibroma with primary hyperparathyroidisim (PHPT) is typical of HPT-JT. It may also include cystic and neoplastic renal abnormalities and uterine tumors....

Odontogenic Calcificant Cystic Tumor (OCCT) is an infrequent injury. It arises from odontogenic epithelial rests present in the maxilla, jaw or gum. Gorlin and col. described the OCCT for first time as an own pathological entity in 1962. Clinically, the OCCT represents 1% of the odontogenic injuries. It is possible to be found from the first decade to the eighth decade. It affects in same propo...

Clear cell odontogenic carcinoma (CCOC) is a rare jaw tumor that was classified as a malignant tumor of odontogenic origin in 2005 by the World Health Organization because of its aggressive and destructive growth capacity and metastasis to the lungs and lymph nodes. We report a case of a 66-year-old female who had swelling, incision and drainage history and a well-defined unicystic radiolucent ...

Primary intraosseous squamous cell carcinoma (PIOSCC) is a rare malignant neoplasm that has an exquisitely exclusive affection to the jawbone. It is defined as squamous cell carcinoma arising within the jaw and developing from residual odontogenic epithelium or from a preexisting odontogenic cyst or tumor. The solid-type of this tumor is a central jaw carcinoma arising de novo and has no initia...
