In this 4 cases, there were 2 males, and 2 females, and 3 cases found on the right side, 1 on the left side of neck. Their ages were 55, 32, 5 and 6, respectively. X-ray examinations and CT scan showed typical characteristics. Chromosome examination analysis with high resolution G band was done for 2 of them, no abnormal changes were found.
