Adenoid cystic carcinoma (ACC) is a rare and slow-growing malignant tumor that typically arises in the salivary glands, but can also occur in other parts of the body such as the breast, lacrimal glands, and trachea.
The term adenoid cystic carcinoma comes from the fact that the tumor is composed of glandular and cystic structures. The tumor cells are typically arranged in small clusters or cords that invade surrounding tissues and nerves. ACC is known for its ability to invade surrounding tissues and to recur after treatment.
The symptoms of ACC depend on the location of the tumor and may include a lump or mass, pain, difficulty swallowing, voice changes, and facial numbness. Diagnosis of ACC typically involves imaging studies such as CT scans or MRIs, as well as a biopsy and laboratory tests to examine tissue samples.
Treatment for ACC depends on several factors, including the size, location, and stage of the tumor. Surgery is the main treatment for ACC, and may involve removing the tumor and adjacent tissues, as well as reconstructing the affected area. Radiation therapy may also be used to kill any remaining cancer cells after surgery. Chemotherapy and targeted therapy are less commonly used in the treatment of ACC, but may be considered in advanced cases.
In summary, adenoid cystic carcinoma is a rare and slow-growing malignant tumor that typically arises in the salivary glands, but can also occur in other parts of the body. It is known for its ability to invade surrounding tissues and to recur after treatment. Treatment for ACC depends on several factors, including the size, location, and stage of the tumor.
