A Case of Branchial cleft fistula / 대한피부과학회지

ABSTRACT

Congenital branchial anomalies are developmental defects resulting from incomplete obliteration of branchial clefts, arches and pouches, and usually found as cysts, fistulas and sinuses. The sinus or fistula is usually noted during infancy and young childhood due to recurrent infection. We have experienced a case of branchial cleft fistula in a 12-year-old male. It was a skin colored, nontender nodule which had mucus secreting from a small opening pore. We performed complete surgical removal and histopathologically the lumen was lined by pseudostratified columnar cells and the stroma was composed of aggregates of lymphocytes with many germinal centers. So we finally diagnosed it as branchial cleft fistula of second type branchial anomaly.
