The glandular odontogenic cyst (GOC) is a rare lesion with odontogenic origin. It shows a propensity for recurrence revealed in 30% of all case. This investigation reports a case of recurrent GOC in a 35-year-old female in the anterior region of the maxilla, which is uncommon and discusses about IHC finding, surgical methods, and differential diagnosis. Under general anesthesia, peripheral bone ostectomy via large round bur for removal of remaining epithelium of the cyst wall was done. Finally liquid nitrogen was used to remaining bone. This article recommends that soft tissue adjacent to the cortical bone perforation should be excised, as well as peripheral bone ostectomy by large round bur for removal of remaining epithelium of the cyst and liquid nitrogen application to the bony cavity. Because of high recurrence rate of the lesion close follow up of the patients is needed.

Background and Objectives: Squamous cell carcinoma of the tongue (SCCOT) is the most common malignant neoplasm in oral cavity. At the time of the diagnosis of SCCOT regional metastases with a high mortality rate are common, which is due to the extensive lymphatic system drainage of the tongue. Although the level of healthcare has significantly improved, the survival rate is still low with an unsatisfactory cure rate. The present study was designed to establish a clinical review on adults with SCCOT and to determine whether the rate of SCCOT has been changed over the 20-year.
Methods: A cohort of 102 patients was recruited for this retrospective study. The study was carried out by reviewing the medical reports and case notes of patients with histologically confirmed SCCOT.
Results: The peak incidence was observed between 60 and 70 years. Stage I disease was found in 24, stage II in 64, stage III in 10 and stage IV in four patients. Seventy-three patients were treated with combined therapy; surgery and radiation, whereas, 29 patients received only surgery. The overall 5-year survival was 60%. Thirty patients developed tumor recurrence including 12 local, 12 nodal, four locoregional, and two distant. Thirty-four patients died during the follow-up period, six with persistent disease, and 62 remained cancer free, giving a mortality and morbidity rate of 39%.
Conclusion: This study recommends aggressive early treatment of patients with SCCOT including resection of the primary tumor with a safe margin (1.5cm) in addition to an appropriate neck dissection.

In 1991, Handlers and colleagues described the Central odontogenic fibroma (COF) as a distinct entity which is a rare benign odontogenic tumour and up to the present, only 78 cases of it have been published. COF usually occurs in an adult patient and has a predilection for the anterior region of the jaws. A 2.8:1 female to mail ratio is typically noted. This article presents a case of COF in a 50-year-old male in the right side of mandible and discuss about the clinic pathological findings, radiographic feature, differential diagnosis, as well as surgical technique of the COF.

Schwannoma(neurilemmoma) is a benign tumor originates from Schwann cells. Ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. Head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. The mandible is the most common site of occurrence for this lesion. We report a rare case of intraosseous ancient schwannoma of the mandible in a 27- year-old woman patient. The tumor located in the ramus and angle region.
