Papillary cystadenoma and cystadenocarcinoma of salivary glands: two unusual entities.
Cystadenoma and cystadenocarcinoma are rare salivary gland tumours histologically characterized by prominent cystic and frequently papillary growth. We present two cases of cystadenoma of a minor salivary gland (upper lip) and parotid cystadenocarcinoma respectively, captured between 834 salivary gland tumors studied in our hospital from 1980 to 2004. The authors review the clinical, histologic...
متن کاملPapillary cystadenoma lymphomatosum (Warthin's tumour).
Papillary cystadenoma lymphomatosum (Warthin tumor, adenolymphoma) is a benign salivary gland tumor that occurs almost exclusively in the parotid gland. It represents 5 to 6% of all salivary gland tumors, and it is the second most common benign parotid neoplasm. Men are affected more often than women, usually in the fifth to seventh decades of life, although this gender proportion is changing. ...
متن کاملPapillary glioneuronal tumor with an unusual bilateral intraventricular localization.
Papillary glioneuronal tumor (PGNT) is a rare brain tumor (World Health Organization grade I) with a glioneuronal dual nature. It has a characteristic morphological pattern composed of astroglial pseudopapillary structures and interpapillary neurocytic elements. The tumor usually occurs in the supratentorial region in children and young adults, with a predilection for the temporal lobe. It is t...
متن کاملPapillary cystadenoma of the lacrimal caruncle.
The adenoma, which was sharply circumscribed but not encapsulated, consisted in part of radiallyorientated, slender, anastomosing papillary processes clothed by double-layered eosinophilic epithelium (Fig. 2). The basal cells of this epithelium were polygonal and relatively small with round nuclei, while the surface cells were tall and cylindrical in shape with conspicuous cell boundaries, gran...
متن کاملPapillary cystadenoma arising from the upper lip: a case report.
We report a rare case of a papillary cystadenoma arising from the upper lip. This tumor was not distinctly encapsulated and had proliferated replacing the ductal epithelium. Mast cells were found not only in the stroma but also in the oncocytic epithelial layer. There was a strong immunoreaction with mitochondrial antibody in the epithelial layer. Only one case (0.9%) of papillary cystadenoma h...
