경구개에 발생한 유두상 타액선종

초록

Sialadenoma papilliferum is a rare benign salivary gland tumor, accounting for approximately 0.4–1.2% of all salivary gland neoplasms. It most commonly occurs in the hard palate, followed by the soft palate, buccal mucosa, upper lip, and, rarely, the esophagus. The condition is typically asymptomatic and is often discovered incidentally during routine oral examinations. We report the case of a 56-year-old man who presented with pain in the left hard palate and was referred to Kyungpook National University Dental Hospital. Enhanced CT revealed a 1.5-cm ovoid lesion in the left paramedian hard palate. Biopsy confirmed the diagnosis of sialadenoma papilliferum, and based on the radiological findings, surgical excision was performed under general anesthesia. The microscopic histopathological examination of the specimen (size: 1.0 x 0.7 cm) revealed papillary proliferation of stratified squamous epithelium with hyperkeratosis and underlying ductal structures lined by mucin-producing cells with mucinous material in the cystic spaces.
