Extraskeletal Ewing's sarcoma (EES) is a rare soft tissue tumor morphologically indistinguishable from the more common Ewing's sarcoma of bone. We report a case of EES arising in the hard palate of 34-yr-old male patient. Microscopically, the monotonous small round cells without neuronal differentiation showed membranous positive immunoreactivity for MIC2/CD99 and vimentin. Ultrastructurally, t...

Pleomorphic adenoma can be defined as a benign mixed tumor composed of epithelial and myoepithelial cells arranged with various morphological patterns, demarcated from surrounding tissues by fibrous capsule. It is one of the salivary gland tumors affecting both major and minor salivary glands. Parotid gland is the most commonly affected of the major group, and palate is the most common site int...

The neurofibroma (NF) is a benign tumor of the peripheral nerve sheath that rarely affects the head and neck. However, among neural lesions, this is the one that most frequently affects this region. The NF can be intra or extra-osseous, alone or multiple (associated with type I neurofibromatosis). The most common extra-osseous mouth NF locations are tongue, oral mucosa and lips. In the literatu...

Oral squamous papillomas are benign proliferating lesions induced by human papilloma virus. These lesions are painless and slowly growing masses. As an oral lesion, it raises concern because of its clinical appearance. These lesions commonly occur between age 30 and 50 years, and sometimes can occur before the age of 10 years. Oral squamous papilloma accounts for 8% of all oral tumors in childr...

Congenital palate defects (CP) occur in dogs. Secondary cleft palate (SCP) is a congenital oronasal fistula resulting in incomplete closure of the hard and soft palate. SCP occurs alone or in combination with primary cleft palate involving the lip and premaxilla. CP results from incomplete fusion of the palatine shelves, most critical at 25 to 28 days gestation. Methods to improve survival of p...

Oral focal mucinosis (OFM); It is a rare soft tissue lesion of unknown etiology. was first described by Tomich in 1974. usually occurs as localized, asymptomatic pedunculated or sessile growth on the gingiva hard palate. In intraoral examination 14-year-old systemically healthy female patient who applied to our clinic with complaint gingival enlargement maxillary palate region, well-circumscrib...

In order to study the influence of dentures on the supporting mucosa, histological and immunohistochemical observations were done on the hard palates of monkeys after being subjected to mechanical stimuli using experimental dentures. The following results were obtained: 1. Light microscopic observations revealed that changes for the most part occurred superficial to the connective tissue papill...

A retrospective review of 4 patients who underwent Surgical resection by trans oral approach was performed for tumors palate. treatment choice variety surgical procedures that be used via approach.
