During this three months, we have experienced 10 cases of tumors, that are 1.6% of all consulted patients, a great percentage compared with 0.25 percentage of Keio University and 0.9% of Niigata University.
It is very interesting that about a half of these tumors were fibrocystic disease including fibrous dysplasia.
Primary sarcoma of 3rd lumbal vertebra and metastatic hypernephroma were also very interesting.
