Multi diameter single fiber reflectance (MDSFR) spectroscopy is a non-invasive optical technique based on using multiple fibers of different diameters to determine both the reduced scattering coefficient (μs') and a parameter γ that is related to the angular distribution of scattering, where γ = (1-g2)/(1-g1) and g1 and g2 the first and second moment of the phase function, respectively. Here we...

Oral cavity squamous cell carcinoma may be more aggressive at presentation and recurrence in young patients compared with older patients. Dysregulation of microRNAs (miRNAs or miRs) has been associated with the development and prognosis of oral cavity cancer. The present study investigated miRNA expression in carcinoma of the oral tongue in young patients. miRNA expression profiles were evaluat...

OBJECTIVES Cathepsin K, a lysosomal cysteine protease, is expressed in the tumor microenvironment (TME) of skin carcinoma, but nothing is known about cathepsin K in oral tongue squamous cell carcinoma (OTSCC). Our aim was to describe the expression of cathepsin K in invasive OTSCC in vitro and in a series of clinical cancer specimens. MATERIALS AND METHODS OTSCC invasion in vitro was studied ...

Metastatic tumors of the oral cavity are rare in occurrence. Renal cell carcinoma (RCC) metastasizes to organs head and neck 12–16% cases. RCC metastases tongue uncommon. A total 63 cases kidney cancer metastasizing have been reported literature. We report a clinical case metastasis skin lower eyelid (as initial manifestation disease) (11 months after diagnosis) one patient with metastatic canc...

Case series Oral manifestations of HIV disease are broadly classified as “strongly associated with HIV”, “less commonly associated with HIV” and “can be seen in HIV infection”. Malignancies reported in HIV infection include Kaposi’s sarcoma, Non-Hodgkin’s lymphoma and squamous cell carcinoma of the oral cavity. At our RagasYRG CARE center, in a cohort of 5760 cases which were screened, 6 patien...

OBJECTIVES 4-nitroquinoline 1-oxide (4NQO)-induced rat tongue carcinogenesis is a useful model for studying oral squamous cell carcinoma. However, gingival changes following 4NQO administration via drinking water are absent in the literature. The aim of this study was to investigate gingival changes concomitant to tongue carcinogenesis induced by 4NQO by means of morphological analysis. METHO...

Background: Oral squamous cell carcinoma (OSCC) occurs in approximately 95% of people older than 40 years; usually, it is diagnosed at the age 60 years. The etiology OSCC multifactorial. Chronic mechanical trauma due to sharp teeth has also been suggested as an oral tongue. Purpose: This case report aimed describe resulting from and prevent further metastasis by correctly diagnosing lesion earl...

Mucoepidermoid carcinoma (MEC) is the most common malignant, locally-invasive tumour of the salivary glands, and accounts for approximately 35% of all malignancies of the major and minor salivary gland. Minor salivary glands are scattered in different areas of the oral cavity such as palate, retromolar area, floor of the mouth, buccal mucosa, lips and tongue. MECs of tongue base are not common....

Pim-1 is a serine/threonine kinase as well as a proto-oncogene that induces T-cell lymphoma. Pim-1 induces cell cycle progression in cooperation with c-Myc and acts as an inhibitor of apoptotic cell death, actions that are involved in blood cell oncogenesis. However, little is known regarding the role of Pim-1 in oral carcinogenesis. We investigated Pim-1 expression in tongue squamous cell carc...
