Upon physical examination, a 2 cm nonfluctuating, nontender, immobile, firm nodular swelling was observed with intact overlying mucosa on the left side of the hard palate in the bicuspid-molar region (Figure 1).

MRI showed a well-demarcated mass of the left side of the hard palate without bone invasion (Figures 2(a) and 2(b)).

The mucosa around the tumor was marked and incised with an adequate margin, followed by dissection, with removal of the whole encapsulated mass and the mucoperiosteum (Figure 3).

The defect on the palate was not reconstructed (Figure 4).
The wound was covered with a fabricated palatal acrylic plate.

fig5
An iodine tampon dressing was placed, and the wound covered with a fabricated palatal acrylic plate (Figure 5).
(a-c) Histopathological examination of the tissue showed a mucosal excision. In the submucosal stroma, there was a multinodular tumor consisting of 2 components. One component showed solid fields of cells with round to oval nuclei and eosinophilic cytoplasm. There was also a component of spindled cells within a myxoid matrix, with perivascular condensation of the cells. The tumor was clearly demarked from the surrounding stroma.
