Adenocarcionma of fetal type is in lung is a newly recognized malignant tumor sharing morphologic features with the epithelial component of the pulmonary blastoma devoid of sarcomatous component. We present a case of adenocarcinoma of fetal type in a 28-year-old female, consisting of numerous branching tubules or glands and morula-like epithelial complexes. Histologically, the tubules and glands were composed of glycogne-rich nonciliated epithelial cells showing in part argyrophilia. Some of tubular and morula-like epithelial cells revealed immunoreactivity for neuron-specific enolase. We report this case with a review of literatures with special references on the histogenisis. This report is the pathologically confirmed second case of the pulmonary adenocarcinoma of fetal type in Korea, following the report of Cho and Lee, 1990.
Key Words: Pulmonary adenocarcinoma of fetal type; pulmonary blastoma; Immunohistochemistry; Histogenesis
