Fine Needle Aspiraton Cytology of Polymorphous Low Grade Adenocarcinoma in the Hard Palate: A Case Report .: Wan Seop Kim, Seok Hoon Jeon, Eun Kyung Hong, Moon Hyang Park, Jung Dal Lee; Korean J Cytopathol. 1998;9(2):181-186.

Abstract PDF: Polymorphous low grade adenocarcinoma(PLGA) is a rare malignant tumor of the salivary gland. It is characterized by diverse histology, bland-looking cytology, indolent behavior and favorable prognosis. The fine needle aspiration cytologic features of PLGA are described. The aspirates from the hard palate in a 33-year-old woman showed cellular smear composed of monotonous small round to oval cells with scanty cytoplasm. Papillary, tubular and cell ball arrangements with characteristic dense stromal spheres were recognized. PLGA could be suggested by fine needle aspiration cytology, if one encountered cellular smear with various architectures and uniform bland-looking cytologic feature.

An Unusual Meningothelial Element in a Hairy Polyp of the Hard Palate.: Si Hyong Jang, Kyueng Whan Min, Woong Na, Se Min Jang, Seung Sam Paik; Korean J Pathol. 2008;42(5):311-313.

Abstract PDF: Hairy polyps are a rare malformations of bigerminal origin that comprise of both ectodermal and mesodermal elements. Meningothelial elements are an extremely rare pathologic finding in hairy polyps. Here we report a case of a hairy polyp with a meningothelial element, which originated from the hard palate. A 1-year-old boy was evaluated for an intraoral mass accompanied by multiple congenital anomalies. A small polypoid mass was noted at the midline of the hard palate. The lesion had central fibroconnective tissue with an unusual stromal component showing reticulated anastomosing pseudovascular patterns. Immunohistochemical staining of the cells lining the pseudovascular spaces and the interstitial cells revealed vimentin and epithelial membrane antigen positivity.
