  • Title: [Low-grade polymorphic adenocarcinoma of papillary type. Morphological and immunohistochemical study].
    Author: Carvalho YR, de Oliveira Nogueira T, de Souza SO, de Araujo VC.
    Journal: Rev Odontol UNESP; 1990; 19(1):165-71. PubMed ID: 1712119.
    Abstract:
    Two cases of polymorphous low-grade adenocarcinoma of the papillary type, from minor salivary glands were studied by light microscopy and immunohistochemistry. One case exhibited a predominance of the papillary pattern, whereas the other presented the following patterns of histological appearance: papillary, solid, pseudocystic and tubular. Utilizing the peroxidase-antiperoxidase (PAP) method, the intermediate filament vimentin, keratin and S100 protein were observed in tumor cells. The immunohistochemical analysis revealed two types of neoplastic cells: myoepithelial and luminal.
