The aim of this study was to evaluate the histopathologic parameters that predict lymph node metastasis in patients with oral squamous cell carcinoma (OSCC) and to design a new assessment score on the basis of these parameters that could ultimately allow for changes in treatment decisions or aid clinicians in deciding whether there is a need for close follow-up or to perform early lymph node dissection. Histopathologic parameters of 336 cases of OSCC with stage cT1/T2 N0M0 disease were analyzed. The location of the tumor and the type of surgery used for the management of the tumor were recorded for all patients...

Melanocytic neoplasms are common in dogs and frequently occur within the oral cavity or in haired skin. The behavior of melanocytic neoplasms is variable and depends on tumor location, size, and histopathologic features. This study compared cytopathology and histopathology of 32 lymph nodes from 27 dogs diagnosed with melanocytic neoplasms. Agreement between the original cytology report, cytology slide review, original histopathology report, and histopathology slide review was determined for each lymph node...

INTRODUCTION: Accurate tumor-node-metastasis(TNM) staging of oral cavity cancer(OCC) is very important in the management of this dismal disease. However, stage migration from cTNM to pTNM was found in a portion of OCC patients. The objective of this study was to determine the possible causes of discrepancy between cTNM and pTNM in OCC and the clinical impacts of stage migration. METHODS: Clinical and pathological data of 252 OCC patients were retrospectively reviewed and compared each other...

Codelivery is a promising strategy to overcome the limitations of single chemotherapeutic agents in cancer treatment. Despite progress, codelivery of two or more different functional drugs to increase anticancer efficiency still remains a challenge. Here, reduction-sensitive lipid-polymer hybrid nanoparticles (LPNPs) drug delivery system composed of monomethoxy-poly(ethylene glycol)-S-S-hexadecyl (mPEG-S-S-C16), soybean lecithin, and poly(D,L-lactide-co-glycolide) (PLGA) was used for codelivery of doxorubicin (DOX) and a Chinese herb extract triptolide (TPL)...

Dermatofibrosarcoma protuberans (DFSP) is an uncommon intermediate-grade soft tissue sarcoma. The tumor is found preferentially on the trunk, whereas the head and neck region are affected in only 10% to 15% of cases. We report the case of a 44-year-old woman with a 5-month history of an asymptomatic, firm, yellow nodule in the mucosa of the right cheek measuring 2.5 cm. The clinical diagnosis was lipoma and an excisional biopsy was obtained. Histopathological analysis revealed a proliferation of spindle-shaped mesenchymal cells arranged in interlacing fascicles amidst fibrous stroma...

Solitary fibrous tumor is a rare neoplasm of mesenchymal origin that usually affects the pleura. This rarity becomes more relevant in the oral cavity since the clinical features are nonspecific. A 66-year-old female patient presented with a 3-month history of a swelling in the floor of the mouth, measuring 2 cm in greatest diameter, and pain symptomatology. Occlusal and panoramic radiographs showed no bone involvement. Ultrasonography of the submandibular and parotid salivary glands revealed normal morphology, dimensions, and echogenicity...

Oral squamous cell carcinoma (OSCC) is one of the most common secondary solid tumors in patients who have undergone hematopoietic stem cell transplantation (HSCT). However, according to previous reports, multiple and recurrent OSCC is very rare. The presented case shows the susceptibility to the development of secondary malignancies, particularly oral cancer, of patients who present with chronic graft-versus-host disease after HSCT. OSCC after HSCT appears to be more invasive and has a tendency to recur, with a poor prognosis...

BACKGROUND: Targeting the mutations and amplifications in the epidermal growth factor receptor (EGFR) gene has curative effects on cancers of the lung, oral cavity, and gastrointestinal system. However, a systemic immune inflammation is an adverse effect of this therapeutic strategy. In this study, we aimed to identify the possible changes in the tumor microenvironment that contribute to the anti-cancer activity of EGFR inhibition. METHODS: Squamous-cell cancers were induced by the syngeneic transplantation of either EGFR-null or wild-type mouse primary keratinocytes that had been transduced with an oncogenic H-ras retrovirus...

Lipomas are very common benign slow-growing soft tissue neoplasms composed of mature adipose tissue mostly diagnosed in the fifth decade of life. These tumors rarely present in the oral cavity, representing less than approximately 5% of all benign mouth tumors. They are usually less than 2cm in size and etiology remains unclear. We report a young male patient presenting with a giant lipoma in the buccal mucosa. Histopathology revealed a large area of mature fat cells consistent with conventional lipoma and an area of the mucosal lining of the lesion suggestive of morsicatio buccarum...

Transformed cells of cancers may be related to stromal cells, immune cells, and some bacteria such as Fusobacterium nucleatum. This review aimed to evaluate carcinogenesis mechanisms of Fusobacterium spp. in the oral cavity, pancreatic and colorectal cancers. These cancers are the three of the ten most prevalence cancer in the worldwide. Recent findings demonstrated that F. nucleatum could be considered as the risk factor for these cancers. The most important carcinogenesis mechanisms of F. nucleatum are chronic infection, interaction of cell surface molecules of these bacteria with immune system and stromal cells, immune evasion and immune suppression...

Hypopharyngeal cancer (HPC) frequently present at an advanced stage, and display early submucosal spread, resulting inpoor prognosis, among the worst of all head and neck subsites. Detection of HPC at an earlier stage would be beneficial to patients. In this study, we used Differential in-gel electrophoresis (DIGE) and two-dimensional polyacrylamide gel electrophoresis (2-DE) proteomics analysis to indentify the potential biomarkers for HPC. Among the differential proteins identified, calcium binding protein S100A9 was overexpressed in HPC tissues compared with normal adjacent tissues, and S100A9 expression in metastatic tissues and advanced tumor tissues was higher than in non-metastatic tissues and early tumor tissues, respectively...
