  13 March

  low-grade spindle cell ameloblastic carcinoma
  Definition: Ameloblastic Carcinoma (AC) is uncommon malignant epithelial odontogenic tumour of jaw, with characteristic histologic features and behavior. Clinically, it has aggressive, infiltrative growth pattern with a distinct predilection for mandible. It exhibits histologic features of ameloblastoma and gets dedifferentiated overtime to culminate in carcinoma. Majority of the cases arise denovo (primary) and only few cases arise from a (...)

• nasolabial cyst
  10 October 2016

  nasolabial cyst Nasolabial cysts are located in the soft tissue just lateral to the nose at the lateral aspect of the maxillary alveolar process. They are thought to arise from the nasolacrimal duct. Non-ciliated pseudostratified columnar epithelium with interspersed mucous cells forms the epithelial lining. These features may be lost through squamous metaplasia. Apocrine metaplasia of the cyst lining has also been (...)

• nasopalatine duct cyst
  10 October 2016

  nasopalatine duct cyst The nasopalatine duct cyst is located within the nasopalatine canal that runs from nose to the oral cavity through the midline of the anterior bony palate, just posterior to the central incisor teeth. The cyst arises from epithelial remnants of the nasopalatine duct, and its lining may be pseudostratified columnar ciliated epithelium, stratified squamous epithelium, columnar or cuboidal epithelium and combinations of these. As surgical treatment comprises emptying (...)
