Adenoid cystic carcinoma of the minor salivary glands / 대한구강악안면방사선학회지

ABSTRACT

Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of the se tumors occurs in the minor salivary glands, especially mucosa of the hard palate. The authors experienced the patient s, who compained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinic al, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary gl ands, obtainted results were as follows: 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic examminations, soft tissue masses were observed with invasion to adjacent structures, and modera te defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic examminations, dark-stained, small unifrom basaloid cells in the hyaline or fibrous stroma we re observed as solid and cribriform patterns, respectively.
