The round mass, measuring 12 mm in diameter, was located in the left buccal mucosa (Figure 1).
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).

T2-weighted imaging (Figure 2(b)).
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).

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)).
Histopathological findings. On hematoxylin and eosin staining, tumor cells were present in the sparse mucoid matrix. The original magnifications were x200.

Microscopically, the tumor cells in the sparse mucoid matrix (Figure 4) exhibited a spindle or stellate shape without nuclear atypia (data not shown).
