Acinic cell carcinoma
Encyclopedia
Acinic cell carcinoma is a tumor
most commonly found in the parotid gland
. The disease presents as a slow growing mass, sometimes associated with pain or tenderness.
These tumors which resemble serous acinar cells vary in their behavior from locally aggressive to blatantly malignant.
It can also appear in the breast
. The pancreatic form of acinic cell carcinoma is a rare subtype of exocrine pancreatic cancer. Exocrine pancreatic cancers are the most common form of pancreatic cancer when compared to endocrine pancreatic cancer.
Acinic cell carcinomas arise most frequently in the parotid gland. Other sites of primary tumors have included the submandibular gland and other major and minor salivary glands. There have been rare cases of primary tumors involving the parapharyngeal space and the sublingual gland. "Acinic Cell Carcinoma Overview." Acinic Cell Carcinoma Information Center.

is a very rare variant of lung cancer that, in this organ, is classified among the salivary gland-like carcinoma of the lung. Fewer than 1% of malignancies beginning in the lower respiratory tract are acinic cell carcinomas.
The prognosis of an acinic cell carcinoma originating in the lung is much more guarded than cases of this rare histotype occurring in most other organs, but is still considerably better than for other types of lung cancer

Tumor
A tumor or tumour is commonly used as a synonym for a neoplasm that appears enlarged in size. Tumor is not synonymous with cancer...
most commonly found in the parotid gland
Parotid gland
The paired parotid glands are the largest of the salivary glands. They are each found wrapped around the mandibular ramus, and secrete saliva through Stensen's ducts into the oral cavity, to facilitate mastication and swallowing and to begin the digestion of starches.-Location:The parotid glands...

Breast
The breast is the upper ventral region of the torso of a primate, in left and right sides, which in a female contains the mammary gland that secretes milk used to feed infants.Both men and women develop breasts from the same embryological tissues...

Epidemiology
Acinic cell carcinoma appears in all age groups, but presents at a younger median age (approx. 52 years) than most other salivary gland cancerSalivary gland cancer
Salivary gland cancer is a cancer that forms in tissues of a salivary gland. The salivary glands are classified as major and minor. The major salivary glands consist of the parotid, submandibular, and sublingual glands. The minor glands include small mucus-secreting glands located throughout the...

Acinic cell carcinoma of the lung is a very rare malignant neoplasm originating from bronchial glands. It is classified as a salivary gland-like carcinoma under the most widely used lung cancer classification system.- External links :...
is a very rare variant of lung cancer that, in this organ, is classified among the salivary gland-like carcinoma of the lung. Fewer than 1% of malignancies beginning in the lower respiratory tract are acinic cell carcinomas.
Prognosis
Prognosis is good for acinic cell carcinoma of the parotid gland, with 5-yr survival rates approaching is 90%, and 20-year survival exceeding 50%.The prognosis of an acinic cell carcinoma originating in the lung is much more guarded than cases of this rare histotype occurring in most other organs, but is still considerably better than for other types of lung cancer
Lung cancer
Lung cancer is a disease characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung in a process called metastasis into nearby tissue and, eventually, into other parts of the body. Most cancers that start in lung, known as primary...

Radiation therapy , radiation oncology, or radiotherapy , sometimes abbreviated to XRT or DXT, is the medical use of ionizing radiation, generally as part of cancer treatment to control malignant cells.Radiation therapy is commonly applied to the cancerous tumor because of its ability to control...
