Low-grade papillary adenocarcinoma of nasopharynx
Definition: Thyroid-like low-grade nasopharyngeal papillary adenocarcinoma (TL-LGNPPA) is an extremely rare neoplasm characterized by morphological analogy to papillary thyroid carcinoma and abnormal expression of thyroid transcription factor-1 (TTF-1).
Histologically, the tumor consists of papillary growth of cuboidal or columnar epithelium. Tubular architecture and a spindle cell component were also observed focally. Some tumor cells (...)

Researchers identify three new susceptibility loci for nasopharyngeal carcinoma in the genome-wide association study they’ve published in Nature Genetics. The team examined 464,328 autosomal SNPs in 1,583 cases and 1,894 (...)
