Abstract
This paper reports a case of branchiogenic fistula on the right side of the neck. The patient was a 15-year-old male with complaint of liquid-oozing from the orifice of the fistula in the right lateral cervical region. The diagnosis could be easily made by radiography with retrograde injection of radio opaque material through the external orifice of the fistula. The fistula exhibited complete lateral cervical type orignated from the second branchial pouch.
The fistula was completely excised surgically under the general anesthesia. The following findings were obtained histopathologically:
1. The inner surface of the fistula was covered with columnar ciliated epithelium.
2. The lymphoid tissue and a thin layer of striped muscle were observed subepithelially.
The embryologic mechanism and histopathological finding were discussed briefly and several literatures were reviewed.
