Translocation events are frequent in cancer and may create chimeric fusions or 'regulatory rearrangements' that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the oncogenic transcription factor MYB as a recurrent theme in adenoid cystic carcinoma (ACC). Whole-genome sequencing data and chromatin(More)
Clear cell calcifying epithelial odontogenic tumour (CCEOT) is a rare variant of calcifying epithelial odontogenic tumor (CEOT). While it is not surprising to find clear cells in odontogenic lesions, the exact nature of the clear cells in CCEOT has not been elucidated. Herein, we report a case of peripheral CCEOT of anterior mandible in a 37 year old black(More)
Sarcomas of the larynx are exceedingly uncommon, of which primary laryngeal osteosarcomas are the rarest. To date, 25 cases of primary laryngeal osteosarcomas have been reported in the literature. Laryngeal osteosarcomas may closely simulate sarcomatoid carcinomas, since both entities share clinical, histological and immunohistochemical features. Herein, we(More)
BACKGROUND Recent discussions have focused on redefining noninvasive follicular variant of papillary thyroid carcinoma (NI-FVPTC) as a neoplasm rather than a carcinoma. This study assesses the potential impact of such a reclassification on the implied risk of malignancy (ROM) for the diagnostic categories of The Bethesda System for Reporting Thyroid(More)
PURPOSE To evaluate the role of high-risk human papillomavirus (HR-HPV) infection in periocular sebaceous carcinoma (SC) using multiple methods of detection, and to determine whether p16 overexpression is present and can be used as a surrogate marker for HR-HPV. DESIGN Retrospective observational case series with laboratory investigations. METHODS(More)
OBJECTIVES The aim of this study was to evaluate a cost-effective oral liquid-based cytology screening test, Shandon Papspin (PS). STUDY DESIGN We compared the diagnostic accuracy of PS with surgical biopsy in 69 patients. Transepithelial cytology specimens were obtained with the use of cervical cytobrushes. Cytology specimens were graded and scored by(More)
