Glandular

**Glandular adenomas are benign tumors of the parenchyma and stroma of the parotid and salivary glands**.\n\nGlandular adenomas are the most common tumor of the salivary glands. 90% of these tumors are ductal adenomas and include nonfunctioning cystic lesions. In 10% of cases, malignant transformation occurs already at the time of diagnosis, which often occurs 2-3 years after the start of observations.\n\nOnly a portion of tumors often lead to the development of cancer. As a rule, transformation is detected during surgery, less often during dynamic observation or x-ray examination, most often revealing it as a stage IV cancer. Therefore, glandular adenoma must be considered as one of the risk groups for cancer, and therefore strict monitoring of all types of these tumors, including early and initial cases of adenomas, should be carried out.\n\nAt the very beginning of development, the disease occurs without symptoms. But the stage before and during the formation of a cyst or lacunar adenoma can last for quite a long time. Only when the cyst reaches a certain size does either the mobility of the jaw and a change in its position in different planes become obvious, or the tumor is simply palpated with the tongue. Next, the patient complains of a deterioration in the appearance of the face. Pain, swelling or other abnormalities are noted by all patients. The clinical picture develops as the tumor grows until it reaches 70-80 mm in diameter. This stage is characterized by the presence of large tumor-like infiltrates of soft tissues and the absence of any signs indicating the participation of the ductal system in the tumor process.\n\nP.S.
