Odontomas are a common type of odontogenic tumors which are regarded as developmental anomalies (hamartomas) rather than a true neoplasm. They occur more commonly in the permanent dentition and are rarely associated with the primary dentition. An odontome comprises of the hard tissues which are laid down in an abnormal pattern. They are considered to be hamartomas rather than neoplasms as they ...

Cystic lesions of the maxillary sinuses include cysts, polyps and neoplasms. Maxillary sinus cysts are benign that commonly an incidental finding during X–ray, since any symptoms do not accompany their presence. An urgent problem is development differential diagnostics, determination indications for surgical treatment optimal tactics patients with cystic sinuses. The authors describe experience...

Background Aims: Diseases of the oral cavity are heterogenous regarding their etiology, pathogenesis, histogenesis and clinical outcomes. The aim this study was to examine frequency diseases encountered in our experience.
 Methods: archives pathology at Jordan University Hospital were retrospectively searched for specimens from 2013–2020. Fisher’s exact test performed statistical differenc...

Antrochoanal polyp is a benign, solitary polypoid lesion arising from the edematous mucosa of the maxillary sinus and extending through the maxillary ostium into the nose. In children, it constitutes 33% of all nasal polyps. It presents most commonly with unilateral nasal obstruction and purulent rhinorrhea. Surgery is the usual treatment for antrochoanal polyps. The primary aim of treatment fo...

BACKGROUND Small cell neuroendocrine carcinoma of the maxillary sinus, a rare malignant tumor, has a poor prognosis because of its high incidence of metastasis. Moreover, metastatic cancer-induced hepatic rupture, characterized by hemoperitoneum, is infrequent, although several lines of evidences have reported that a wide variety of other neoplasms can cause this usually fatal manifestation. ...

SMARCB1 (INI1)-deficient sinonasal carcinoma is a recently described variant of sinonasal tract carcinoma characterized by complete loss of nuclear SMARCB1 (INI1). It is very rare and currently underdiagnosed because of a lack of awareness. Before the description of SMARCB1 (INI1)-deficient sinonasal carcinomas, these tumors were probably misclassified as various malignant neoplasms. To date, o...

odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. the lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

Sinonasal malignant neoplasms comprise only 3% of all head and neck malignancies. Synchronous and metachronous tumors of the head and neck have been described, but rarely have there been reports of a single tumor with two distinct histologies. Here, we describe a case of a sinonasal malignant neoplasm with two distinct histologies. A case report and literature review was performed. We present a...
