Subcutaneous bronchogenic cyst of the chest wall: A case report with brief literature review.

INTRODUCTION

Bronchogenic cysts are congenital lesions found in the mediastinum, particularly the posterior-superior area. The current study aims to report a rare case of a subcutaneous bronchogenic cyst in the chest wall.

CASE REPORT: A 41-year-old patient presented with a swelling of the chest wall. The mass had been present since birth. On examination, there was a large soft, round mass over the sternum subcutaneously. It was a fixed, non-flatulence, non-pulsatile, and non-tender mass.

DISCUSSION: Usually, the condition develops between the fifth and sixteenth weeks of gestation, when the primordial intestine separates into two parts: dorsal, which gives rise to the esophagus, and ventral, which gives rise to the pulmonary bud and tracheobronchial tree. As a result, the cyst is an ectopic lung bud that may or may not be connected to the tracheobronchial tree but lacks mesenchymal tissue.

CONCLUSION

Although chest wall bronchogenic cysts are uncommon, they should be considered in the differential diagnosis of cystic and soft tissue lesions in adults with chest wall swelling.
