case_images: The round mass, measuring 12 mm in diameter, was located in the left buccal mucosa (Figure 1).
case_images: Magnetic resonance imaging of the tumor. (a) T1-weighted MRI showed a mass with low intensity in comparison with skeletal muscle tissue (yellow dot) while (b) T2-weighted MRI revealed a lesion with high intensity in comparison with adipose tissue (yellow dot).

case_images: T2-weighted imaging (Figure 2(b)).
case_images: Gross appearance of the resected specimen (a). The surgical specimen measured 2 cm at its largest diameter and was filled with glossy, mucoid, and milky white secretions (b).

case_images: This was diagnosed as a benign buccal tumor and was subsequently resected under local anesthesia. The tumor was easily dissected from the surrounding tissue and appeared to be covered with a thin fibrotic capsule. The resected specimen measured 2 cm at its largest diameter (Figure 3(a)) and was filled with glossy, mucoid, and milky white materials (Figure 3(b)).
case_images: Histopathological findings. On hematoxylin and eosin staining, tumor cells were present in the sparse mucoid matrix. The original magnifications were x200.
