Abstract:
First branchial cleft anomalies constitute less than one percent of all branchial arch anomalies. First branchial clefi anomalies are classified into 2 digerent types with different embryologic, anatomical and histologic features by Work (1972)1. Among 2 types, type II anomaly is less common than type I and there has been no report of type II anomaly in the Korean literatures. We experienced a 5-year-old female who had a inflammed cystic mass over neck which was extended into parotid area After elevation of parotidectomy skin incision and superficial parotid gland, the cystic mass was observed to be extended upward into the parotid gland, medial to the facial nerve and ended at the external auditory canal. Microscopic examination shows that cyst wall is lined with squamous epithelium and contains some mesodermal tissue such as pilosebaceous gland and muscle. In conclusion, we can present this case as the first branchial cleft anomaly type II.
