A Case of Cutaneous Bronchogenic Cyst with Lymphoid Follicles / 대한피부과학회지

ABSTRACT

We report a case of cutaneous bronchogenic cyst accompanied by many lymphoid follicles histopathologically. A 6-year-old boy had an erythematous macule with a pinpoint-sized opening intermittently draining mucinous material on the anterior chest. Histopathologic findings showed an irregularly folded cystic structure extending from the deep dermis to subcutis. It was lined by ciliated pseudostratified columnar epithelium interspersed with PAS-positive goblet cells. Groups of submucosal glands, a strand of smooth muscle, and, interestingly several lymphoid follicles consisting of many mononuclear cells were also seen.
