A = Photograph showing clinical appearance of the myoepithelioma located on
the left side of the soft palate. An elevated maxillary torus can also be
seen in the anterior part of the hard palate.. B = Low power photomicrograph showing histological picture of the
myoepithelioma. The lesion can be seen in the submucosa and recovered by a
stratified oral squamous epithelium (hematoxylin and eosin stain, original
magnification x25).. C = Photomicrograph showing the myxoid pattern of the tumour (hematoxylin and
eosin stain, original magnification x100).. D = High power photomicrograph showing the types of tumour cells encountered:
spindle, plasmacytoid and epithelioid (hematoxylin and eosin stain, original
magnification x400).

An elevated maxillary torus could also be noticed in the anterior part of the hard palate (Figure 1A). The histological examination revealed the presence of tumour originating from a minor salivary gland and covered by a stratified squamous oral epithelium (Figure 1B). The tumour cells were arranged in order to form a myxoid pattern (Figure 1C) and, individually, small and/or medium spindle-shaped cells with predominantly round or ovoid nuclei, as well as epithelioid and palsmocytoid cells were noted (Figure 1D). The stroma was myxomatous and no ductal or syringomatous epithelial structures were observed (Figures 1B and 1C).
