Submandibular gland tumor symptoms?

summary

In submandibular gland epithelial tumors, benign and malignant accounted for about 1 / 2. All benign tumors were mixed tumors; Adenoid cystic carcinoma is the most common malignancy, followed by mucoepidermoid carcinoma. Submandibular gland tumors, whether benign or malignant, are characterized by masses in the submandibular triangle.

Submandibular gland tumor symptoms?

Benign mixed tumor was painless slow growth, clear perimeter, tumor activity, round, also can be a typical nodular. Malignant tumors generally grow faster, but there are also several years of history, the mass is hard, often with spontaneous pain or tenderness and nerve involvement symptoms.

When the lingual nerve is involved, there may be Glossalgia or numbness, especially in the tip of the tongue; When the lingual nerve is involved, the symptoms of tongue paralysis may appear, that is, the movement of the tongue is limited, the tip of the tongue is tilted to the affected side when the tongue is extended, and the tongue muscle may atrophy and have muscle tremor in severe cases; When the marginal mandibular branch of the facial nerve was involved, the affected side of the mouth angle drooped and the red lip could not be everted.

Adenoid cystic carcinoma of submandibular gland is asymptomatic in the early stage, which seems to be a benign tumor. The course of the disease is long, the growth is slow, the size of the tumor varies, the tumor is oblate or slightly nodular, and the texture is hard. Adenoid cystic carcinoma is more active at the beginning, but it often infiltrates the surrounding tissue and has limited activity.

matters needing attention

Adenoid cystic carcinoma is especially easy to infiltrate the nerve and expand along the nerve fiber bundle, resulting in pain and other symptoms. Mucoepidermoid carcinoma is usually well circumscribed and can be solid or cystic. Spontaneous rupture can flow out light brown and viscous fluid.
