We present a rare branchial cyst of the nasopharynx in a 57-year-old man. The cyst was located at the higher level between the roof and the left lateral band of the nasopharynx, and was removed by the endonasal approach following a preparatory septoplasty. While several cases of nasopharyngeal cysts have previously been reported, this appears to be the first case of the resection of such a cyst via the endonasal approach, and is a useful, and potentially less injurious, alternative to the transpalatal approach.
A case of lymphoepithelial cysts (LECs) in the mediastinum, manifested radiographically by paratracheal air collection, is reported. Percutaneous injection of radiopaque material and indocyanine green into a cyst showed an opening to the trachea. During surgical resection, three well-circumscribed cysts were isolated. Pathologically the cysts were lined by a ciliated columnar epithelium and surrounded by lymphoid tissue with germinal centers. Judging from the level of the duct opening onto the airway, these LECs might have derived from a remnant of the fourth branchial pouch. To the authors' knowledge, this is the first case described.
A case of a carcinoma-in-situ developing in a lateral cervical cyst (branchiogenic carcinoma) is described and compared with metastatic cervical lymph nodes (due to cancers from unknown primary sites). The authors are convinced that branchial carcinomas do exist, but are extremely rare. The available literature is reviewed.
