One correction- Basal cell adenoma was initially called monomorphic adenoma, and is recognized as having several patterns. So the two groups illustrated here would all fall into the category of basal cell adenoma, some with a solid pattern, and others with a tubular or trabecular pattern. The differential diagnosis per PathOutlines would be:
Adenoid cystic carcinoma:
Infiltrative growth pattern, perineural invasion
Basal cell adenocarcinoma:
Invasive growth pattern
Pleomorphic adenoma:
Chondromyxoid stroma blended with epithelial cells, BCA with prominent myoepithelial derived stroma and stroma in BCA does not blend into the epithelial nests
Canalicular adenoma:
Double columns of cells forming anastomosing canaliculi with paucicellular stroma
