새열 기형으로 오인된 경부에 발생한 이소성 침샘조직 1예

초록

Heterotopic salivary gland tissue (HSGT) consists of salivary tissue in places where it doesnot normally exist. Usually, HSGT presents as a draining sinus or nodule of the neck. Thepathogenesis of HSGT of the neck remains uncertain. But HSGT in the neck is most widelythought to arise from defective closures and ectodermal hetroplasia of the precervical sinus ofHis. HSGT in the neck is rare and only a few cases have been reported in Korea. We recentlyexperienced a case of HSGT in the neck presenting as a fistula of the anterior lower neck. Wethought this as a 2nd brachial cleft anomaly; however, biopsy revealed HSGT. HSGT in theneck should be considered as one of the causes of a neck mass or fistula in children. Herein,we report this case of HSGT with a literature review.
