title: Clinicopathologic features of oral squamous papilloma and papillary squamous cell carcinoma: a study of 197 patients from eastern China.
abstract: Oral squamous papilloma and papillary squamous cell carcinoma are 2 clinicopathologically distinctive papillary epithelial tumors. The current study aims to compare the clinical and pathologic features of these oral papillary lesions in a patient population from eastern China. A retrospective review in a series of patients with clinical and pathologic diagnosis of oral squamous papilloma (n = 141) and papillary squamous cell carcinoma (n = 56) was conducted. The average age of oral squamous papilloma was 51.0 years (male-to-female ratio, 1.82), with the palate being the predominant site. The average age of oral papillary squamous cell carcinoma was 63.3 years (male-to-female ratio, 1.67), with the gingiva being the predominant site. Multivariate analysis revealed that the elderly patient with papillary lesion (≥60 years) was associated with 3.09-fold (95% confidence interval, 1.59-6.03) increased carcinoma risk compared with the nonelderly patient. The lesion located on the gingiva was associated with 4.98-fold (95% confidence interval, 1.96-12.63) increased carcinoma risk compared with other oral sites. Collectively, clinicopathologic features of oral squamous papilloma and papillary squamous cell carcinoma in eastern China were elucidated. Elderly patients with oral papillary lesions located on the gingiva correlate with higher carcinoma risk. It highlights the importance of using a histologic examination to confirm the clinical diagnosis for any suspicious papillary lesions.
