“…Plasmacytoid cell tumors tend to occur more frequently in the oral cavity, whereas spindle cell types have been reported to occur in the parotid gland (3). The cell type is unrelated to differences in the biological behavior, recurrence rate, or the patient age (4).…”

We describe the enhancement patterns of myoepithelioma in two patients with a soft palate mass. In the first case, helical CT revealed a faintly enhancing mass. Histologically, the tumor was composed of plasmacytoid cells in a background of rich myxoid stroma. Immunostaining for CD34 showed scanty blood vessels. In the second case, helical CT revealed an intensely enhancing mass. Histologically, the mass was a cellular tumor with fibrous stroma. Immunostaining for CD34 also showed frequent blood vessels.

“…Usually, myoepithelioma presents multiple cellular patterns as fusiform, plasmacytoid, epithelioid, clear cell, mixed pattern, and abundant presence of mucoid acellular stroma [3,4,6,9,12,18,19,20]. The plasmacytoid type tends to occur more often in the oral cavity, especially in the palate, when compared with other types of myoepithelioma, although the fusiform pattern is the most common and often primarily affects the parotid gland [3,4,18]. Patterns containing epithelioid cells and clear cells develop in the parotid glands and often suffer malignant transformation [6].…”

“…However, it was only in 1991 that it was considered by the World Health Organization as a distinct pathological entity. Also known as myoepithelial adenoma, this tumor is composed entirely of myoepithelial cells, without duct formation in its interior and makes up about 1-1.5% of all salivary gland tumors [2,[3][4][5][6][7][8][9][10][11][12][13][14]. It affects both minor and major salivary glands, but is more commonly found in the parotid (about 50%), sublingual (33%), and submandibular glands (13%) [13,15].…”

Myoepithelioma originating from the floor of the mouth

Introduction Myoepithelioma primarily affects the parotid gland and usually presents as a slow-growing painless lump. The aim of this paper is to report a case of myoepithelioma in the mouth floor. Case outline A young man noticed a painless increased volume in the left side of the mouth floor region, which after one year of evolution presented as a sessile tumor with normal colored mucosa and the absence of secretion output. Computed tomography with contrast showed an image with slightly heterogeneous density, with well-defined limits. Incisional biopsy was performed under local anesthesia, and pathology examination of the sample revealed a myoepithelial neoplasm. Total excision of the lesion was performed under general anesthesia, and histopathological examination confirmed the diagnosis of the salivary gland myoepithelioma. The patient did not present signs of relapse after a year of follow up. Conclusion Despite the fact that myoepithelioma originating in the salivary gland are considered rare, especially in the mouth floor, this tumor should be considered in the differential diagnosis of similar lesions. Proper treatment appears to be complete surgical excision and post-operative follow-ups shows should be carried out as long as possible, despite the fact that relapses are extremely rare.

“…The cellular patterns of myoepitheliomas consists of plasmacytoid cells, spindle cells, epitheloid cells, and clear cell patterns which do not account for differences in recurrence rate, biological behavior, or the patient age. In oral cavity, plasmacytoid cell type is more commonly seen while spindle cell type is more frequently seen in parotid gland [8]. Myoepithelial cells are most commonly seen in salivary glands.…”

Myoepitheliomas are rare benign tumors of myoepithelial cell origin, most commonly seen in parotid gland. These tumors are also reported in oral cavity, soft palate being the most common site of involvement. Imaging findings are nonspecific, and histopathology is necessary to differentiate from other tumors. Our case showed mildly enhancing well-circumscribed mass in soft palate with histological findings consistent with myoepithelioma. The aim of this case report is to increase the awareness about this rare benign tumor regarding its morphological, histopathological, and radiological features along with its possible differential diagnosis.
