Neurilemmoma is a benign nerve sheath tumour that is composed entirely of well-differentiated Schwann cells. Schwannomas arise when proliferating Schwann cells in the perineurium causing displacement and compression of peripheral, motor, sensory, sympathetic andcranial nerve sheath. They may occur at any age, but the peak incidence is 3rd and 4th decades with no sex predilection. Histopathological picture shows primarily of Schwann cells in a poorly collagenized stroma. The treatment of choice is surgical excision with goodprognosis and rare secondary complications.We describe a clinical case of intraosseous schwannoma located in the right pretragus area in a 48-year-old female patient. It is important to highlight that the schwannoma is usually found in the head and neck, and rarely in the oral cavity. Intraosseous neurilemmomas are rare, and they represent less than1%of all benign primary bone tumours. © 2012 John Wiley & Sons A/S. Source

The Present study was carried out to evaluate the morphology of soft palate in Oral Submucous Fibrosis (OSF) patients using digital lateral cephalogram. A total number of 70 patients were included in the study (Control group had 35 patients and Study group had 35 OSF patients) were evaluated for soft palate by digital lateral cephalogram. The anterio-posterior length and superior-inferior length of soft palate were measured. The morphology of soft palate was categorized as type 1, to type 6. Different types of soft palate were compared with stages of OSF. Among the Study group (35 patients) 62.9% had Stage 2 OSF. Leaf shaped (Type 1) soft palate was seen commonly in stage 2 OSF whereas butt shaped (Type 3) in stage 3 OSF. In the present study there was statistically significant difference in length (anterio-posterior) of Type 1 soft palate of OSF patients. In the present study as the OSF progressed to advanced stage there was gradual change from Type 1 and Type 2 variety of Soft palate to Type 3 and Type 6 variety of soft palate. The study observed that there was gradual reduction in the length of soft palate in anterior-posterior direction in OSF patients. © 2013 European Association for Cranio-Maxillo-Facial Surgery.

Ultrasound has been introduced into the medical field around 1940s, since than it has been widely used. It has been found many adherents in the fields of ophthalmology and obstetrics and gynecology. It has proved invaluable in cardiology and abdominal diseases. In recent years, the role of ultrasonography in the head and neck has expanded dramatically. It is used in establishing differential diagnosis of cystic neck masses, solid masses and lymphadenopathies. It not only serves for the differentiation between benign and malignant lymphadenopathy and also between intraglandular and extraglandular abnormalities of the salivary glands, with 90-95% accuracy. © 2013 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

Abrikossoff tumor or Granular cell tumor usually present as unencapsulated, small, firm white mass, usually less than 2 cm with infiltrative borders. The histogenesis seems to be neural and most likely Schwann cell in origin. The lesion will present as an asymptomatic mass usually in the submucosa. Usually it behaves as a benign lesion; however, about 2% of the cases can present a malignant course. Here we report a case of large diffused painful swelling in the palate in a 9 year old boy. This was diagnosed as benign granular cell tumor on histopathologically, but had malignant clinical characteristics. © 2011 Ashwini, et al. Source

The incidence of extranodal non-Hodgkin's lymphomas (NHL) in Asian subcontinent is very low. Extranodal NHL in the malar region are uncommon, and the incidence of these lesions in such site is unknown. Here is a case of slowly enlarging mass from the soft tissueover the right malar region, radiographically appeared to have involved maxillary sinus and histopathologically diagnosed as round cell tumour. Immunohistochemistry analysis was suggestive of diffused large B-cell lymphoma. Definitive diagnosis by immunohistochemistry is a must for accurate diagnosis, treatment and better outcome for such lesions. © 2011 John Wiley & Sons A/S. Source
