Squamous odontogenic tumor (SOT) is an unusual, benign odontogenic tumor presented in close physical relationship to the dentition and originating from the epithelial rests of Malassez in the periodontal ligament or gingival epithelium. It was first described in 1975 by Pullon et al. and there are few cases reported in the literature. The main characteristic of this lesion is a tendency to arise in the molar region of the mandible and in the premolar-canine region of the maxilla with a simultaneously asymptomatic swelling in the alveolar. SOTs are incidental discoveries on routine dental radiographs or panoramic x-rays in many cases. We report a case of a 60-year-old Caucasian woman with SOT of the mandible in the area of the right premolars.

Intraoral pleomorphic adenoma is a rare entity, with the most common site of appearance being the palate. As a benign lesion, it rarely involves underlying structures. The aim is to present a case of a palatal pleomorphic adenoma (cellular) with bone involvement, with reference to clinical and histological features of the tumour, emphasis on diagnostic and therapeutic management and comparison with the findings of similar studies in the literature. Pleomorphic adenomas of the palatal minor salivary glands remain a rather rare clinical condition, and it is unusual to infiltrate the adjacent palatal bone. A thorough clinical imaging and histological/cytological examination should always be performed to define the benign or malignant nature of the lesion, preoperatively.

Myopericytoma (MPC) was accepted as a separate entity by the World Health Organization in 2002 and it describes a lesion which comprises of myoid-like oval to spindle-shaped cells with a concentric perivascular type of growth. We present two unusual cases of MPC in the maxillofacial region. In our case management included complete surgical excision under general anesthesia and regular post-operative follow up. Myopericytomas belong to one of the three categories comprising a broader and heterogeneous group of lesions called Hemangiopericytoma (HPC)-like neoplasm's. These include glomangiopericytoma, infantile myofibromatosis (formerly known as infantile HPC), and portion of sinonasal HPC. A clinically relevant characteristic of hemangiopericytoma is its unpredictable clinical course which is often not related to its histopathologic characteristics. The latter course is in contrast to the benign course of MPC, thus it is essential for practitioners to differentiate between those two diagnoses.
