D10-D36: Benign neoplasms

D11: Benign neoplasm of major salivary glands

Benign neoplasms of major salivary glands are non-cancerous growths that form in the primary salivary glands, which include the parotid, submandibular, and sublingual glands. These tumors grow slowly and do not spread to other parts of the body. While the exact cause of these neoplasms is unknown, factors such as previous radiation therapy to the head or neck, and certain genetic conditions may increase their risk. These growths may present as a slow-growing painless mass in the face, mouth, or neck, but larger ones can cause discomfort or impede normal functioning. In some cases, these neoplasms may constrict the nerves in the area, potentially leading to facial weakness or numbness. The progression of the condition is typically slow, and symptoms become more noticeable as the tumor grows. In general, benign neoplasms of the major salivary glands do not impact overall health significantly unless they grow large or impinge on vital structures.
