저자들은 2례의 제2새열낭종을 경험하였다. 증례 1은 26세의 여자에서 3년 전부터 서서히 크기가 증가하다가 1년 전 임신과 함께 현저히 크기가 증가한 병력이 있으며, 낭종은 우측 악하부와 흉쇄유돌근 전내측에 위치한 무통성의 파동을 보이는 $7.5{\times}5{\times}4cm$ 크기의 연성 종물로서 내외측으로 누공 형성은 없었다. 증례 2는 56세 남자에서 2년전 악하간극 농양으로 진단하고 절개 및 배농을 시행한 병력이 있으며, 낭종은 좌측 악하부와 흉쇄유돌근 전내측에 위치한 무통성의 파동을 보이는 $5.5{\times}4{\times}3cm$ 크기의 연성 종물로서 역시 내외측으로 누공 형성은 보이지 않았다. 조직학적으로 중층편평상피로 이장되어 있었고 상피 하방에서는 림프양 조직이 관찰되었으며, 완전절제술을 시행한 다음 술후 $3{\sim}4$년이 경과된 현재까지 재발이나 다른 합병증 없이 양호한 경과를 보이고 있다.

Developmental anomalies arising from the branchial apparatus include cysts, external sinuses, internal sinuses, and complete fistulas. Second branchial cleft cysts are by far the most common among these anomalies. It may occur at any age, being most common in the third decade, and more frequent in the male than in the female. It usually presents a smooth, round, nontender fluctuant mass located between the level of the tragus and the clavicle along the anteromedial border of the sternocleidomastoid muscle. It is lined by respiratory or squamous epithelium unless inflammation is present. The considerable amount of lymphoid tissue may be found beneath the epithelium. The treatment of choice of branchial cleft cyst is surgical excision. If the lesion is acutely infected, however, it is essential to relieve the infection prior to the surgery. This report deals with two cases of second branchial cleft cyst. In case 1, the cyst had rapidly increased in size over pregnant period. In case 2, the patient presented the swelling in the left neck, and had the history of incision and drainage because of misdiagnosis as submandibular space abscess. The infection was treated by antibiotic therapy in the first place, and then complete surgical excision was made. There was no evidence of any recurrence or complications for these $3{\sim}4$ years.
