Is Mucoepidermoid carcinoma is it serious?
Generally, there is a good prognosis for low-grade tumors, and a poor prognosis for high-grade tumors, however recent research have found reoccurring low grade tumors also have a poor prognosis.
What causes Mucoepidermoid carcinoma?
Mucoepidermoid carcinoma develops when a cell randomly acquires changes ( mutations ) in genes that regulate how the cell divides such that it begins to grow quickly, forming a cluster of cells (a mass or lump).
Is Mucoepidermoid carcinoma aggressive?
Background Mucoepidermoid carcinoma (MEC) of salivary glands is a malignant, locally aggressive neoplasm with metastatic potential.
Can Mucoepidermoid carcinoma come back?
Nonetheless, subsequent metastases of a few of the previously benign tumors has led to all mucoepidermoid tumors being considered carcinoma. They can recur, and they can metastasize to regional lymph nodes or distant viscera.
What is the treatment of Mucoepidermoid carcinoma?
Surgical resection is the mainstay of treatment for all grades of MEC. Local resection of the cancer is considered sufficient treatment for low-grade tumors. High-grade tumors are generally treated with surgical excision with wide margins followed by postoperative radiotherapy.
Is Mucoepidermoid carcinoma common?
Mucoepidermoid carcinoma (MEC) is the most common salivary gland malignancy in children and adults, and the most common malignancy of the major and minor salivary glands.
Does Mucoepidermoid carcinoma metastasize?
Metastasis of the primary lesion to the left triceps was diagnosed following a swelling noticed by the patient during the 2-year follow up period. Mucoepidermoid carcinoma can be a low, intermediate or high-grade malignancy and can metastasize to different parts of the body.
Is Mucoepidermoid carcinoma caused by HPV?
High risk human papillomavirus (HPV) is firmly established as an important cause of oropharyngeal carcinoma. Recent studies have also implicated HPV as a cause of mucoepidermoid carcinoma (MEC)—a tumor of salivary gland origin that frequently harbors MAML2 translocations.
What does Mucoepidermoid carcinoma look like?
Most tumors are smaller than 4 cm in diameter. Cysts of variable sizes are often present, and they usually contain brownish fluid. MEC cells form sheets, islands, duct-like structures, and cysts of various sizes. The cysts may be lined with intermediate, mucous, or epidermoid cells, and they are filled with mucus.
What is Oncocytic carcinoma?
Oncocytic carcinoma, also known as malignant oncocytoma, is a malignant carcinoma. It can occur in many organs, including the breast and the pancreas, but it occurs most frequently in the thyroid. 1. The occurrence of oncocytic carcinoma in the salivary glands has rarely been reported.
What is Lymphoepithelial carcinoma?
Lymphoepithelial carcinoma (LEC) is an uncommon malignant tumor composed of undifferentiated malignant epithelial cells with characteristic lymphoid stroma. [1,2] The most common location of LEC is the nasopharynx.
