Abstract::
Ectopic thymic tissue is an unusual finding that is generally asymptomatic. We present a case series of five
pediatric patients with cervical ectopic thymuses. In two patients, the ectopic thymic tissue was symptomatic, and in three
patients it was an incidental finding. We highlight the need to include this anomaly on the differential diagnosis for a
pediatric neck mass. We also propose observation, rather than surgical excision, as the treatment of choice for
asymptomatic cervical ectopic thymus.
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.
