Abstract

Primary lung adenocarcinomas are rare in pediatric patients, and even rarer in patients without precedent malignancy or congenital malformation. Here we present the first reported case of primary lung cribriform adenocarcinoma with squamoid morules in a previously healthy adolescent female. Molecular testing identified CTNNB1 mutation in the tumor and excluded other common mutations in lung adenocarcinoma. Our case suggests molecular alterations to the same signaling pathway can lead to similar histomorphology regardless of the tissue of origin.
