Encapsulated Minimally Invasive Epimyoepithelial Carcinoma of Submandibular Gland - A New Entity?? With Review of Literature
Epimyoepithelial carcinoma (EMC) is a rare low-grade salivary gland malignancy comprising of 1% of all the salivary glands tumors. EMC is a rare tumor when involving submandibular gland (8.6%) as compared to parotid gland (62.1%). A thorough pubmed literature search retrieved only 17 cases of EMC involving submandibular gland since 1972. EMC can present in classical pattern characterised by biphasic cell population with inner layer of cuboidal to columnar cells and outer layer of myoepithelial cells. Encapsulated minimally invasive epimyoepithelial carcinoma is a recently coined terminology by Seethala et al. To the best of our knowledge, this is the first case of encapsulated minimally invasive EMC of submandibular salivary gland discussed in the literature. The present paper highlights the review of literature of EMC involving submandibular salivary gland, histomorphological spectrum and diagnostic differentiation from other salivary gland tumors.
