CT and ultrasound features of basal cell adenoma
of the parotid gland: a report of 22 cases with pathologic correlation.
These tumors mostly arise de novo (77%), but they might also arise from preexisting basal cell adenomas
Neville, "Basal cell adenomas
of the minor salivary glands.
The CA has been traditionally categorized with other several uncommon benign salivary gland tumours for many years.1 Thus, CA and basal cell adenoma
(BCA) were called together as \'monomorphic adenomas.\'3,6,7 Since the CA and BCA have been determined to have distinct clinical and histopathological features,5,6,8-10 the term of monomorphic adenoma is revised.
(92-94) Rotellini et al (95) examined 101 benign and malignant salivary gland tumors, including 36 pleomorphic adenomas, 8 myoepitheliomas, 3 basal cell adenomas
, and 1 canalicular adenoma among the benign tumors; 16 mucoepidermoid carcinomas, 10 adenoid cystic carcinomas, 8 acinic cell carcinomas, 8 polymorphous low-grade adenocarcinomas, 7 salivary duct carcinomas, and 4 epithelial-myoepithelial carcinomas among malignant tumors.
The congenital basal cell adenoma
of salivary glands.
Other tumors from the basaloid neoplasm category, such as basal cell adenoma
and basal cell carcinoma, were not available to use.
In the present study after histological confirmation 67.5% cases were found to be pleomorphic adenoma, 20% mucoepidermoid carcinoma, 7.5% Warthin's tumour, 2,5% basal cell adenoma
and remaining 2.5% cases were found to be adenoid cystic carcinoma.
In other cases, PLGA can be indistinguishable from PA and basal cell adenoma
, especially the tubulotrabecular variant.

(9) It can be a source of confusion with tumors such as basal cell adenoma
, adenoid cystic carcinoma and mucoepidermoid carcinoma--low grade on cytology.
