Most lesions are found in the mediastinum, along the tracheobronchial tree or in the lung parenchyma. Cutaneous or subcutaneous bronchogenic cysts are rarely reported. Our patient was the second case in the English literature who had a cyst over the manubrium sterni in adult life. Surgical total excision is the definitive treatment of extrathoracic bronchogenic cysts, needle aspiration management should not be tried because of association with malignant lesions as mucoepidermoid carcinoma and malign melanoma have been reported to arise from them.eninfo:eu-repo/semantics/openAccessBronchogenic cyst; Presternal; Subcutaneous cystArticle601596110.5578/tt.21642-s2.0-8486214452218468022554369Q3
