Cyst, bronchogenic J98.4

Rare, solitary, congenital, embryonic malformation of the tracheo-bronchial tree or the gill arch furrow.

In childhood; girls are more often affected than boys.

Above the manubrium sterni, pre-sternal, on the neck or above a shoulder blade.

Rarely secreting, reddish-brown, 0.5-1.0 cm large node with a smooth surface. Not clinically recognizable as a malformation. Only the localization of the lesion (e.g. above the manubrium sterni) and the congenital occurrence allows a tentative diagnosis. Otherwise histological random diagnosis.

Cystic structure in the dermis and/or subcutis which is lined by a highly prismatic ciliated epithelium, more rarely a squamous epithelium. In the cyst wall evidence of smooth muscles, mucus glands and rarely cartilage.

Therapy not necessary.
