There is a hard lump on the face near the ear without pain or sliding, which mostly refers to the swelling in the area centered on the earlobe and close to the cheek. Because of its bad mobility, it may be related to malignant tumor of parotid gland, among which mucoepidermoid carcinoma of parotid gland, adenoid cystic carcinoma of parotid gland are the most common ones, and also non-Hodgkin’s lymphoma of parotid gland is also possible.
1. Mucoepidermoid carcinoma of parotid gland: women are more common than men, and those occurring in parotid gland often present painless lumps with slow growth. The size of tumor varies, the border can be clear or unclear, the texture is moderately hard, the surface can be nodular, and the hard lump can be touched in the face near the ear without pain or sliding. When the tumor invades the facial nerve, facial paralysis may occur.
2. Adenoid cystic carcinoma of parotid gland: it is most common in the minor salivary glands of palate and parotid gland, and the tumor is easy to spread along the nerves, and neurological symptoms, such as localized pain, facial paralysis, numbness of tongue or paralysis of hypoglossal nerve can be seen. The tumor is extremely invasive and has no boundary with the surrounding tissues. At the beginning of the disease, there may be a hard lump in the face near the ear without sliding.
3. Non-Hodgkin’s lymphoma of parotid gland: this disease is a malignant tumor originated from lymph nodes or lymphatic tissues. As there are lymph nodes in the parotid gland, when the lesion appears here, there can be the above signs.
