Expression of β- and β-adrenergic receptors in oral squamous cell carcinoma and their association with psychological and clinical factors.

Background: Psychological stressors have been related to tumor progression through the activation of beta-adrenergic receptors (β-AR) in several types of cancer.

Purpose: This study aimed to investigate the expressions of β- and β-AR and their association with psychological and clinicopathological variables in patients with oral squamous cell carcinoma.

Methods: Tumor samples from 99 patients diagnosed with OSCC were subjected to immunohistochemical reaction to detect the expression of β-AR and β-AR.

Pleomorphic sarcoma of maxillary sinus: Clinical report of a patient initially diagnosed with denture-induced fibrous hyperplasia.

A 74-year-old woman displayed a large nodular lesion in the maxillary alveolar mucosa, which was initially identified as denture-related fibrous hyperplasia. Although her prosthodontist has adjusted the maxillary complete denture to relieve pressure on the lesion, it increased in size over time.

In situ melanoma of oral cavity: Diagnosis and treatment of a rare entity.

Oral melanoma is an extremely aggressive and rare tumor. Commonly, oral melanomas are diagnosed as invasive tumors, which considerably reduces the chances of cure. In situ oral melanomas being exceedingly rare, which makes its clinicopathological and prognostic characteristics poorly known.
