A case of juvenile carcinoma of mammary gland in a 5 years old girl was reported. Only 32 cases of breast cancer in those under 19 years of age have been reported in Japan. The number of the cases in children under 10 years of age is extremely few totalling only 2 cases, including our case. The prognosis was different between the cases in Japan and those in foreign countries. This may be due to the difference in histology.
