This is particularly promising for the differentiation of pleomorphic adenomas and Warthin's tumors
as well as carcinomas.
associated with IgG4-related disease.
The diagnosis was solitary parotid gland extraintestinal salmonellosis within Warthin's tumor
, secondary to uncomplicated bacteremia accompanying enterocolitis.
Pleomorphic adenoma was the most predominant tumor (38%) followed by Warthin's tumor
which was also reported by other studies.
We sought to investigate the immunohistochemical expression of ER, PgR and AR in a large sample of pleomorphic adenomas (PA), Warthin's tumors
(WT), mucoepidermoid carcinomas (MEC) and adenoid cystic carcinomas (ACC) of salivary glands, regarding particularly the tumorigenesis role of these receptors.
Mucoepidermoid carcinoma arising in Warthin's tumor
of the parotid gland.
The differential diagnosis of lymphoepithelial cysts includes Warthin's tumor
, salivary duct retention cyst (mucocele), dysgenetic polycystic disease of the salivary gland, and mucosa-associated lymphoid tissue (MALT) lymphoma.
Like a cystic mass of the parotid, the most differential diagnoses include retention cysts, posttraumatic sialoceles, Warthin's tumor
, mucoepidermoid carcinoma and necrotic metastases.
