• pleomorphic adenoma with extensive squamous metaplasia
  23 April 2018

  Synopsis
  pleomorphic adenoma with extensive squamous metaplasia +/- keratin cyst formations squamous metaplasia, sometimes with the formation of keratin pearls, can be present. possible formation of extensive keratin-filled cysts lined by squamous epithelium. Extensive squamous metaplasia can be mistaken for malignancy, including mucoepidermoid carcinoma and squamous cell carcinoma.

• salivary gland tumors with squamous cell differentiation
  23 April 2018

  Examples
  salivary mucoepidermoid carcinoma (of the salivary glands)
  squamous cell carcinoma of salivary glands The squamous cell carcinoma of submandibular salivary gland is a malignant epithelial tumor of major salivary glands composed of epidermoid cells / squamous cells. squamous cell carcinoma of salivary glands accounts for about 0.9-4.7% of all salivary gland tumors with a predilection to occur in parotid gland due to perinodal involvement. Primary squamous cell carcinoma of (...)

• salivary low-grade cribriform cystadenocarcinoma
  4 April 2018

  Low-grade cribriform cystadenocarcinoma of salivary glands
  Definition: Low-grade cribriform cystadenocarcinoma (LGCCC) is a rare tumor of salivary gland which exhibits clinically indolent behavior.
  This tumor predominantly consists of intraductal components and frequently exhibits papillary-cystic or cribriform proliferation pattern.
  Considering the histological features of LGCCC, it should be distinguished with :
  papillocystic variant of acinic cell carcinoma
  conventional salivary (...)

• submandibular gland
  10 March 2018

  WKP
  Definition: The paired submandibular glands (historically known as submaxillary glands) are major salivary glands located beneath the floor of the mouth. They each weigh about 15 grams and contribute some 60–67% of unstimulated saliva secretion; on stimulation their contribution decreases in proportion as the parotid secretion rises to 50%.

• canalicular adenoma

  Definition : Canalicular adenoma is a benign neoplasm of a salivary glands which originally was considered to be a variant of basal cell adenoma.

  It is most common in the 7th decade of life but can occur from 4th to 9th decades of life. It has a greater tendency to involve the minor salivary glands.
  Approximately 70%-90% of the tumors occur in the oral cavity and is particularly common in the upper (...)

  9 February 2018

  Low-grade cribriform cystadenocarcinoma of salivary glands
  Definition : Low-grade cribriform cystadenocarcinoma (LGCCC) is a recently described rare tumor of salivary gland which exhibits clinically indolent behavior.
  This tumor predominantly consists of intraductal components and frequently exhibits papillary-cystic or cribriform proliferation pattern.
  Considering the histological features of LGCCC, it should be distinguished with papillocystic variant of acinic cell carcinoma, (...)

• salivary basal cell adenoma with cribriform pattern
  9 February 2018

  Definition: Subtype of salivary basal cell adenoma.
  Differential diagnosis
  adenoid cystic carcinoma (AdCC) Cribriform type of salivary basal cell adenoma (cBCA) is relatively rare and problematic in distinction from adenoid cystic carcinoma (AdCC). Good circumscription, lack of infiltrative properties, and absence of MMP9, laminin, CD117, and myoepithelial marker (SMA, S100 and calponin) in the cells around the cribriform spaces, are the most reliable points for differential diagnosis (...)

  Definition : collagenous spherulosis in salivary tumors.
  Type of tumors
  collagenous spherulosis in an epithelial-myoepithelial carcinoma (#12021508#)
