Shishegar5 reported myoepithelioma, basal cell adenoma
and oncocytoma to constitute 4.
Trabecular type of basal cell adenoma
, polymorphous low grade adenocarcinoma and the other rare salivary gland tumours are differential diagnosis for CAs, thus immunohistochemical observations are required.
CT and MRI findings of basal cell adenoma
of the parotid gland.
5% Warthin's tumour, 2,5% basal cell adenoma
and remaining 2.
No Myb expression was seen in basal cell adenoma
, oncocytoma, adenosquamous carcinoma, acinic cell carcinoma, and salivary duct carcinoma.
This general pattern overlaps with other benign and malignant basaloid-type salivary gland neoplasms, with the primary differential considerations being pleomorphic adenoma (PA) and, less-commonly, basal cell adenoma
and basal cell carcinoma.
10) Since then, various terms have been used to describe this tumor, including congenital basal cell adenoma
, basaloid adenoma, and congenital hybrid basal cell adenoma
--adenoid cystic carcinoma.
The differential diagnosis of ACC includes tumors that also exhibit tubular and cribriform structures such as polymorphous low-grade adenocarcinoma, tumors with basaloid cellular morphology such as basal cell adenoma
and basal cell adenocarcinoma, and tumors with a dual population of ductal and myoepithelial cells such as pleomorphic adenoma.
PA = Pleomorphic Adenoma, WT = Warthin's Tumor, ME = Myoepithelioma, BCA = Basal Cell Adenoma
, MEC = Mucoepidermoid Carcinoma, ACC = Adenoid Cystic Carcinoma, CAPA = Carcinoma Ex-Pleomorphic Adenoma)
