Abstract PURPOSE: Although the most common neoplastic lesion of the oral cavity is squamous cell carcinoma (SCC), primary neoplastic lesions of the hard palate have not been systematically reviewed to date. The aim of this study was to determine the histopathologic composition and characteristics of neoplasms of the hard palate. MATERIALS AND METHODS: A retrospective analysis of 66 patients with a primary neoplasm of the hard palate managed at the authors' institution from 1985 through 2012 was performed. Demographic features, malignancy rate, histopathologic characteristics and distribution, TNM staging results, metastasis patterns, and management strategies were investigated. RESULTS: The sample was composed of 66 patients (mean age, 45.0 yr; 57.6\% men). Neoplasms were benign in 57.6\% of cases and malignant in 42.4\%. Epithelial neoplasms and mesenchymal neoplasms were encountered in 52 patients (78.8\%) and 14 patients (21.2\%), respectively. Minor salivary gland tumors (MSGTs) were the most common histopathologic group (60.6\%), followed by benign mesenchymal tumors (15.2\%), SCCs (12.1\%), malignant melanomas (6.1\%), lymphomas (3.0\%), and sarcomas (3.0\%). Although 75.0\% of malignant epithelial neoplasms were at an advanced stage, there were no pN+ SCC or malignant MSGT cases at presentation. CONCLUSION: The most common neoplasms of the hard palate were MSGTs. SCCs were relatively rare in this series. Although three-fourths of neoplasms were at an advanced stage, neck metastasis was not a characteristic of malignant epithelial neoplasms located in the hard palate.
