いわゆる頸部血液嚢胞の一症例

抄録

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.
