Epithelial-myoepithelial carcinoma of the minor salivary glands: a case report
2018
Epithelial-myoepithelial carcinoma of the salivary gland--a low grade malignant neoplasm? Report of two cases and review of the literature.
1999
Summary Epithelial-myoepithelial carcinomas (EMC) are rare neoplasms of the salivary gland with an incidence of less than 1% arising predominantly in the parotid gland. Although they are thought to be of low grade malignancy, fatal courses are described. We report a case of EMC of the parotid gland in a 58-year-old woman with an unfavorable course of this disease in long term follow-up. The malignant potential of this tumor is discussed. In addition, we include another case of EMC of the submandibular gland.

Unusual epithelial-myoepithelial carcinoma in palate: case report and immunohistochemical study
2010
Ephitelial-myoepithelial carcinoma (EMC) is a neoplasm of salivary gland extremely rare and low-grade malig- nant, exhibiting predilection for major salivary gland, especially parotid gland. This paper described a case of EMC localized in soft palate. The initial clinical diagnosis were mucoepidermoid and adenoid cystic carcinoma. A incisional biopsy was performed, and the histological diagnosis was adenocarcinoma not otherwise specified. The patient underwent excisional biopsy, where was realized immunohistochemical analysis, staining the duct-like structures, where the inner layer of epithelial cells positively for CK 14, whereas outer layer of myoepithelial cells stained positively for s…
Das basaloide Plattenepithelkarzinom (BSC) der Mundschleimhaut
1997
The basaloid-squamous carcinoma (BSC) that was first described in 1986 by Wain et al. for the head and neck region is a rare distinct variant of squamous cell carcinoma (SCC). The cardinal histopathologic feature is a biphasic cellular pattern of basaloid and squamous components. BSC has been confused with solid adenoid cystic carcinoma (ACC). Although the number of reported cases is small, BSC appears biologically virulent, with a propensity to aggressive local behavior, early regional and distant metastasis, and subsequent poor survival. We report the clinicopathological characteristics of 4 new cases and compare their immunohistochemical features with those of solid ACC and conventional …
