Lateral cervical cyst is a rare disease occuring in the head and neck region. The highest percentages of cases occur in the 20-40 year age bracket. Although, over the years, many theories have been put forward for discussion, no agreement has been reached as to the origin of this disease. Clinically this disease is usually called "Branchial cyst" or "Lympho-epithelial cyst". This time, we dare to call it "Lateral cervical cyst" from the view of anatomical point. This disease generally exhibits a benign nature, but in rare cases it degenetates into a malignant tumour. Recently, we experienced a case of a comparatively large lateral cervical cyst from the angle of mandible to the lateral cervical region. The cyst was extirpated completely under N.L.A. modified general anesthesia. About one and a half years after the operation no recurrence or malignant degeneration has appeared.
