Cutaneous bronchogenic cyst: a rare presentation as anterior chest wall cystic mass

Abstract

Bronchogenic cysts are uncommon and occur along the trachea-bronchial tree, lungs and mediastinum and even more uncommon in the skin tracheo-bronchial tree especially the anterior chest wall. It is a congenital abnormality that arises as a result of abnormal budding along the foregut in early embryogenesis. The diagnosis is usually missed clinically and majority of the cases are histologically diagnosed. The diagnosis in our case was histologically made and revealed a fibromuscular cyst wall lined by pseudostratified ciliated columnar epithelium with few goblet cells and sub-epithelial mucinous glands. We report a case of  cutaneous bronchogenic cyst that occurred in the skin of the anterior chest wall over the manibrium sterni.
