Abstract
Bronchopulmonary foregut malformation (BPFM) is a rare anomaly of accessory pulmonary tissue that usually arises from esophagus or stomach. We present a case of extralobar pulmonary sequestration (ELS) connecting with the esophagus by a cyst, the inner wall of which is lined with squamous epithelium or respiratory epithelium. BPFM is sometimes used to group a number of ventral anomalies of accessory pulmonary tissue. The term currently refers specifically to those lesions composed of sequestrations that retain communication with the gastrointestinal tract. Usually the communication is a well-formed muscular tube lined with stratified squamous or columnar epithelium. The presence of both epithelia in a communication that is a component of the BPFM suggests embryogenesis. We describe an adult with BPFM composed of ELS and a connecting stalk to the esophagus by a foregut cyst that contains both squamous epithelium and respiratory epithelium.
