Mucoepidermoid carcinoma of parotid arises from:
Muco epidermoid carcinoma is the M/C type of malignant salivary gland tumor. Mucoepidermoid tumor consists of following cells: Squamous cells * Mucus secreting cells Intermediate hybrid cells * Clear or hydropic cells. (progenitor of other cells) No myoepitheliai cells are seen Mucoepidermoid tumors similar to other tumors is more common in parotid and has a female predominance. They are malignant tumors which are slow growing and can invade facial nerve Histologically, the greater is the ratio of epidermoid element, the more malignant is the behavior of the tumor They are more aggressive in minor salivary glands as compared to major salivary glands. Low-grade tumors are more common in children Management Total parotidectomy with preservation of facial nerve Total parotidectomy Facial nerve may be sacrificed if it is invaded by tumor Radical neck dissection may be done.
