An Unusual Case of Hybrid Odontogenic Tumor in Type 1 Myotonic Dystrophy Patient.

Myotonic dystrophy, also referred myotonic muscular dystrophy, is an autosomal dominant, slowly progressive, multisystem disease characterized by skeletal muscle weakness, wasting, and myotonia. A hybrid tumor of odontogenic apparatus is a lesion showing combined histopathological characteristics of two or more previously recognized odontogenic tumors and/or cysts of different categories. We, therefore, report a case of hybrid tumor (adenomatoid odontogenic tumor associated with calcifying cystic odontogenic tumor) in a myotonic dystrophic patient.

Greig Cephalopolysyndactyly Syndrome with Oral Manifestations: A Rare Case Report.

Greig cephalopolysyndactyly syndrome (GCPS) is one of the autosomal dominant-inherited syndromes, caused by haploinsufficiency of the GLI3 gene. It is a rare, multiple congenital syndrome with an estimated rate of 0.009%. With the classic clinical triad of preaxial polydactyly with cutaneous syndactyly of at least one limb, hypertelorism, and macrocephaly, presumptive diagnosis of GCPS is made. The purpose of this article is to report a case of GCPS with emphasis on craniofacial and oral features.

A large oral lipoma in a young patient: A rare combination.

Lipoma is a benign neoplasm of mature fat cells. Although a common mesenchymal neoplasm of trunk and extremities, its occurrence in the oral and oropharyngeal region is rather rare. Lipoma accounts for 1-5% of all benign oral tumors, occurring in patients above 40 years of age with slight male predilection. Oral lipoma presents as asymptomatic, slowly growing mass rarely exceeding 25 mm in diameter. Documented here is a rare case of a large size lipoma (>3 cm in diameter) occurring as an extraoral swelling in a girl aged 13 years, which was subsequently diagnosed and treated 4 years later. Furthermore discussed are the peculiarities in the clinical presentation, differential diagnosis, and investigations for this case.

Oral fluid nanosensor test: saliva as a diagnostic tool for oral health.

High-impact diseases, especially cancer, are challenging to diagnose without supplementing laboratory testing. Even with laboratory tools, definitive diagnosis often remains elusive. The oral fluid nanosensor test technology platform combines cutting-edge technologies--such as self-assembled monolayers, bionanotechnology, cyclic enzymatic amplification, and microfluidics--with several well-established techniques including microinjection molding, hybridization-based detection, and molecular purification. The intended use of the OFNASET is for the point-of-care multiplex detection of salivary biomarkers for oral cancer.

High-grade mucoepidermoid carcinoma of maxillary sinus.

Malignant tumors of the paranasal sinus are uncommon, constituting less than 1% of all malignancies and 3% of all head and neck cancers. Nonsquamous cancers of the maxillary sinus are even rarer as is evident from the limited data available on the clinical characteristics and outcomes. Mucoepidermoid carcinoma accounts for 13% of all malignancies occurring in maxillary sinus. We report a rare case of high-grade mucoepidermoid carcinoma of maxillary sinus in a 45-year-old female along with review of the literature.

Central giant cell granuloma mimicking an adenomatoid odontogenic tumor.

Central giant cell granulomas are non-neoplastic lesions of unknown etiology. They affect females more than males with the mandibular anterior region being the most common site of occurrence. Clinically central giant cell granulomas present as asymptomatic, expansile swellings causing deviation of associated teeth. Radiologically they usually presents as multilocular lesions causing expansion or perforation of cortical bone. Central giant cell granulomas are usually confused as other lesions both clinically and radiologically, and a definitive diagnosis can be made only histologically. We report here a rare case of central giant cell granuloma in association with congenitally missing tooth which was misdiagnosed to be an adenomatoid odontogenic tumor both clinically and radiologically. This case report also highlights yet another unique presentation of central giant cell granulomas that is in association with a congenitally missing maxillary lateral incisor.

Pleomorphic adenoma of the soft palate: myoepithelial cell predominant.

The pleomorphic adenoma is the most common salivary gland tumor. A remarkable morphological diversity can exist from one tumor to the next. We present here a case of pleomorphic adenoma of minor salivary glands of the soft palate which had predominantly myoepithelial cells with minimal stroma, ductal cells, or tubular elements.
