Published: July 1994

One case of myo-epithelioma occurring in the parotid gland is reported. This tumor was composed of spindle cells. The diagnosis was confirmed by ultrastructural and immunohistochemical analysis demonstrating myofilaments aggregation pattern and positive staining for S100-protein and keratin antibodies. Of all salivary gland tumors, myo-epithelioma accounts for less than 1% of the total and has a good prognosis. Conservative surgical management is curative.

Myoepithelial tumours are rare and distinct entities with uncertain histogenesis. They occur primarily in major salivary glands and soft tissue around the head and neck. Bony involvement predominantly occurs in facial bones.

Although myoepithelioma is defined as a benign tumour made up primarily of neoplastic myoepithelial cells, its actual histopathological characteristics are highly diverse. It can be considered a rare disease. The most common site of occurrence is the parotid gland, followed by the minor salivary glands of the palate.

Soft tissue myoepithelial tumors (METs) are diagnostically challenging tumors that require careful histologic and immunohistochemical characterization for accurate classification. Nearly half of METs show recurrent EWSR1 or FUS gene rearrangements with a diverse set of fusion partners. The diversity of fusion partners and lack of known driver abnormalities in many cases raises the question of whether METs represent a uniformly distinct tumor entity.

Adenomyoepithelioma (AME) is a rare variant of breast neoplasm. It is a biphasic tumour characterized by small epithelial-lined spaces with inner luminal cells and outer of abluminal (myoepithelial) cells. Either - or both - of these two cells may rarely undergo malignant transformation.

Objective: The clinical characteristics and prognosis of primary epithelial-myoepithelial carcinoma of salivary gland (EMC-SG) have not been defined well due to its rarity. The purpose of this study is to assess the proportion of EMC-SG among salivary gland cancers, describe the clinicopathological features and prognosis of this disease, further analyze the factors associated with EMC-SG survival, and establish individual survival-predicting models.

Methods: Data on patients diagnosed with salivary gland malignancy between 2000 and 2020 were collected from the Surveillance, Epidemiology, and End Results database.
