NCI Definition: A squamous cell carcinoma arising from the hypopharynx. Signs and symptoms include dysphagia, hemoptysis, and the presence of a neck mass. [1]

Hypopharyngeal squamous cell carcinomas most frequently harbor alterations in TP53, CDKN2A, KMT2D, CCND1, and PIK3CA [2].

Most Commonly Altered Genes in Hypopharyngeal Squamous Cell Carcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, TP53 Exon 7 Mutation, and TP53 Exon 5 Mutation are the most common alterations in hypopharyngeal squamous cell carcinoma [2].
