A case of capillary hemangioma of the tongue increased in size during pregnancy is reported in this paper.<BR>When a 20-year-old female patient was 8 months pregnant, she noticed a small painless tumor at the apex of the tongue. The tumor rapidly grew during 9 to 10 months of pregnancy. But after delivery, the tumor did not show increased size. Intraoral examination revealed at the time of visit to our hospital, a pedunculated tumor mass of the tongue with a lobulated surface. Surgical extirpation was performed under local anesthesia 2 months after delivery. Histologically the tumor was composed of multinodular masses consisting of many small capillaries lined by single layer of endothelial cells. Ulcerations of covering epithelium with mono-nuclear cell infiltration were seen.<BR>By above-mentioned clinical and histological findings, it was suggested that the behavior of the present tumor had some relationships to pregnancy hormonal unbalance.
