Intraductal Papillomas From the Parotid Gland.

Intraductal papillomas have been mostly described in minor salivary glands but are extremely rare in the parotid gland. Consequently, limited information is available to guide otolaryngologists and pathologists in managing intraductal papillomas, specifically in the parotid gland. Diagnosing intraductal papillomas in this location poses significant challenges.

Complete mitochondrial genome sequence and mutations of the laryngeal cancer model inbred nude rat strain.

In the present work, we undertook the complete mitochondrial genome sequencing of an important laryngeal cancer model inbred rat strain for the first time. The total length of the mitogenome was 16,308 bp. It harbored 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one non-coding control region (D-loop region).
