Cutaneous bronchogenic cysts are rare lesions that thus far have been reported to occur in the regions of the lower part of the neck,1 sternum, and shoulders.2,3 We report a case herein of a cutaneous ciliated cyst, occurring on the chin, that is compatible with bronchogenic cysts. Bronchogenic cysts have not been previously reported to occur at this site, to our knowledge.
Report of a Case
A 1-year-old boy had a small, painless cystic swelling, of a few months' duration, on his chin. The cyst was excised.
The resected specimen consisted of an elliptical piece of skin with a unilocular subcutaneous cyst, measuring 0.6 × 0.5 cm, that contained cloudy gelatinous fluid.Microscopic examination showed a cyst that was lined with ciliated pseudostratified columnar epithelium, predominantly of respiratory type, and squamous epithelium. Occasional groups of mucus glands and smooth muscle bundles were present in the wall.
