carcinoma:

or tumor,
tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. Feedback controls limit cell division after a certain number of cells have developed, allowing for tissue repair

An exceedingly peculiar variant of this tumor has been described as acinic cell carcinoma with high-grade transformation/dedifferentiation which is characterized by the coexistence of both low-grade acinic cell carcinoma and a high-grade dedifferentiated component, as well as by an accelerated clinical course.
Tumors for which this phenomenon is well characterized include acinic cell carcinoma, adenoid cystic carcinoma, and epithelial-myoepithelial carcinoma.
[28] Acinic cell carcinoma was diagnosed in 4 (3.50%) cases, 2 cases each were seen in parotid and submandibular glands and was seen in 3rd and 5th decade which is similar to the study conducted by Fernandes GC et al.15 Two case of adenoid cystic carcinoma were diagnosed involving the minor salivary glands which are also similar to other studies [15].
Parotid acinic cell carcinoma is a rare, slow-growing, malignant tumor with imaging findings indistinguishable from other parotid tumors.
Acinic cell carcinoma may be distinguished by DOG1 positivity.

The most common types of parotid cancer (n = 672) were mucoepidermoid carcinoma (n = 270 [40.2%]), acinic cell carcinoma (n = 200 [29.8%]), and adenoid cystic carcinoma (n = 61 [9.1%]).

The tumors with frequent and high SOX10 expression are acinic cell carcinoma, adenoid cystic carcinoma, epithelial-myoepithelial carcinoma, myoepithelial carcinoma, and pleomorphic adenoma, which presumably show similarities to acini and intercalated ducts.
