چکیده

Adenocarcinomas of the sinonasal tract may originate from respiratory surface epithelium or the underlying seromucinous glands. These malignancies are divided into salivary-type adenocarcinomas and non-salivary-type adenocarcinomas. The latter are further divided into intestinal-type and nonintestinal-type adenocarcinomas. This review provides an update on tumor classification, differential diagnostic considerations and molecular features, as well as new adenocarcinoma entities in the sinonasal area.

Intestinal-Type Adenocarcinoma: Classification, Immunophenotype, Molecular Features and Differential Diagnosis

Intestinal-type adenocarcinoma is the second most frequent sinonasal adenocarcinoma. High incidence of these tumors is seen among workers with occupational wood dust exposure, particularly of hardwood dusts. Intestinal-type adenocarcinoma has striking histomorphologic and immunophenotypic similarities with colorectal adenocarcinomas, but on the level of molecular pathologic mechanisms these tum...

An unusual case of low-grade tubulopapillary adenocarcinoma of the sinonasal tract

BACKGROUND Low-grade papillary adenocarcinomas of the sinonasal tract are rare neoplasms. Over recent years, little doubt remains that this tumour represents a separate entity based on morphology, ultrastructural features and behaviour. We outline a case of this rare entity displaying a not hitherto described immunophenotype. CASE PRESENTATION A 32 year old man presented recurrent epistaxis w...

Genome-wide analysis of genetic changes in intestinal-type sinonasal adenocarcinoma.

BACKGROUND Intestinal-type sinonasal adenocarcinomas are rare tumors related to professional exposure to wood dust. Little is known about the genetic changes in these tumors. METHODS Twenty-two tumors were analyzed by microarray comparative genomic hybridization (CGH). In addition, DNA ploidy was measured by flow cytometry and microsatellite instability (MSI) by multiplex PCR. RESULTS The m...

Sinonasal lymphomas in Indonesia: immunophenotype and Epstein-Barr virus association

Sinonasal lymphoma is a rare disease with NK/T-cell (NKTC) or B-cell immunophenotype. Previous study revealed the geographic difference in frequency of NKTC lymphoma (NKTCL) and almost constant association with Epstein-Barr virus (EBV) infection. Through review of 41 cases with sinonasal lymphoproliferative diseases registered in the Department of Anatomical Pathology, University of Indonesia d...

Invasive sinonasal adenocarcinoma with an absent olfactory bulb: a case report

Sinonasal adenocarcinomas are rare, locally invasive tumours. In this case the symptomatic profile was unusual and the diagnosis was missed at the primary care stage. Interestingly this would be the first documented case with an absent ipsilateral olfactory bulb. A 55-year old male presented with symptoms of behavioural change and mild headaches. He was later found to have a large Sinonasal ade...
