Presternal cutaneous bronchogenic cyst: a rare case
Keywords:Cutaneous bronchogenic cyst, Presternal, Lymphoid follicles
Cutaneous bronchogenic cysts are rare congenital anomalies arising from the ventral foregut that forms the respiratory system as a result of abnormal budding of the bronchial tree during embryogenesis between 4th and 6th weeks of gestation. In the majority of the cases, pre-operative diagnosis is difficult, and the diagnosis is usually a histopathological surprise. We report a case of cutaneous bronchogenic cyst of the presternal location, which presented as a subcutaneous nodule with a discharging fistula. Histopathology showed a cyst lined by respiratory type of epithelium and unusual presence of lymphoid follicles around the cyst wall.
