A Case Report of So-Called Cervical Blood Cyst

Abstract

An eight-year-old boy with a dark red color fluid containing cyst adjacent to the internal jugular vein beneath the carotid sheath is reported. He had had no operations or trauma on his neck before. Pathological examination of the cyst wall revealed its origin to be a medium-size vein. Although we could not find the term "cervical blood cyst" in the current classification of head and neck tumors, we found the term used in the Japanese literature before 1970.
