What is a low-grade salivary gland neoplasm?

What causes acinic cell carcinoma?

The exact cause of salivary gland cancers, including acinic cell carcinoma, is unknown; however, research suggests that possible causes of the disease may be previous exposure to radiation, wood dust inhalation, and a family history of salivary cancers.

What is polymorphous low grade adenocarcinoma?

What is polymorphous adenocarcinoma?

What is the most common malignant salivary gland tumor?

Mucoepidermoid carcinomas are the most common type of salivary gland cancer. Most start in the parotid glands. They develop less often in the submandibular glands or in minor salivary glands inside the mouth. These cancers are usually low grade, but can sometimes be intermediate or high grade.

Can acinic cell carcinoma spread to the lungs?

CONCLUSION. AiCC of the parotid gland is viewed as a low-grade neoplasm with good curative outcomes and low likelihood of metastasis. With metastasis, however, it does exhibit a tendency to spread to the lungs.

Is myoepithelial carcinoma A sarcoma?
