Raised granules in the sublingual gland are usually caused by oral ulcers, sublingual gland cysts and mucous gland cysts, which require prompt medical treatment.
1. Oral ulcers often appear as single or multiple round ulcers of different sizes on the oral mucosa or under the tongue, and their surfaces may be covered with a yellow or grayish-white pseudomembrane, which can be mistaken for raised granules in the sublingual gland.
2. Sublingual gland cysts are usually caused by the blockage of the distal duct of the sublingual gland, which can be manifested as purple-blue and soft raised granules, and a certain sense of fluctuation can be felt when touched.
3. Mucous gland cysts are usually associated with inflammatory stimuli, and may appear as blue translucent blisters on the ventral side of the sublingual gland or the tip of the tongue, as if the sublingual gland has a raised granule, and they are easily ruptured by bites during eating.
