Carcinoma originating from the surface epithelium of the nasopharynx is classified by the World Health Organization (WHO) as nasopharyngeal carcinoma (NPC) and has 3 main types: keratinizing squamous cell carcinoma (WHO type 1) and nonkeratinizing carcinoma, differentiated (WHO type II), and undifferentiated (WHO type III). Nonkeratinizing NPC is strongly associated with prior Epstein–Barr virus (EBV) infection. These tumors may be divided into differentiated and undifferentiated carcinoma. Histologically, the tumor is characterized by syncytia of large malignant cells with vesicular nuclei, conspicuous nucleoli, and easily observed mitotic figures. We report a case of a 14-year-old boy diagnosed with EBV and human papillomavirus (HPV)-positive NPC (WHO type 3) with cytogenetics showing the presence of mosaic trisomy 2. This case report brings to light a rare cytogenetic aberration to our knowledge only reported once before in the literature in a xenograft model.
Multi-disciplinary teams present the framework in the increasingly
challenging care provided for patients. Wang et al. present a 37 year
old female who is 35 weeks pregnant when a rare cardiac angiosarcoma is
diagnosed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
