Abstract:
Squamous cell carcinoma throughout the epithelium of a lateral cervical cyst is considered extremely rare. This report describes an additional case of this very rare clinical condition. A 70-year-old man presented with a well-defined, immobile, painless mass in the left neck that was excised with a diagnosis of branchial cyst. Histologic findings of the excised specimen were lateral branchial cyst with high-grade dysplasia and carcinoma of the squamous epithelial lining. The patient was followed for more than 2 years 10 months and no evidence of recurrence or other cancer has been found.
