In the present study, we report the case of an infant whose mother received tamoxifen for breast cancer while unaware of the pregnancy. The infant, born at 29 weeks and 6 days of gestational age with a birth weight of 1664 g, had no congenital anomalies. This case presents detailed information on the development of an infant with placental transfer of tamoxifen. The infant has grown and developed normally throughout a 5-year follow-up period, but long-term vigilance continues.}, title = {A Follow-Up Report of an Infant Born to a Mother Receiving Tamoxifen}, volume = {2020}, year = {2020}, yomi = {カナイ ユウ and ドキ, コウスケ and ホンマ, マサト and ミヤゾノ, ヤヨイ and タカダ, ヒデトシ} }
