A 29-year-old man presented to our hospital with a 2-week history of painless swelling on his upper chest. Physical examination revealed a subcutaneous mass of 3 cm in diameter on the right sternoclavicular joint. Histologically, the cyst wall consisted of stratied squamous epithelium including some areas of pseudostratied ciliated columnar epithelium with goblet cells. No cartilage, smooth muscle, seromucous glands, or lymphoid follicles were found around the cyst. Based on his age, the location, clinical course, and histological ndings of the tumor, it was diagnosed as a cutaneous bronchogenic cyst. We reviewed the clinicopathological features in 108 previously reported cases of cutaneous bronchogenic cysts, and found that their histological features are similar to those of branchial cleft cysts in some cases. Thus, both clinical and histological ndings should be considered when diagnosing cutaneous bronchogenic cysts. Skin Research, 18 : 71-78, 2019
