化膿性肉芽腫は，膿原性肉芽腫と呼ばれ皮膚や粘膜に生じる隆起性病変であり，口腔領域も好発部位の1つとされている^1）。妊娠中に発生すると妊娠性腫瘍とも呼ばれる^1）。臨床的には，急速に発育し易出血性の肉芽腫を形成する疾患といわれている^2）。今回われわれは，舌に発生した化膿性肉芽腫の1例を経験したので，臨床経過に文献的考察を加えて報告する。

Pyogenic granuloma is a benign rapidly growing hemorrhagic lesion that occurs on the skin and mucosa. As pyogenic granulomas often occur on the oral mucosa during pregnancy,they are called pregnancy tumors. The author experienced a case of pyogenic granuloma on the tongue in a pregnant woman.

　A 34-year-old woman of one month pregnant was aware of a mass in her tongue since 33th week of her pregnancy. The mass increased rapidly in size. Excision of the lesion under local anesthesia was performed at about 3 month postpartum. Histologic examination revealed a pyogenic granuloma. The postoperative course was uneventful and there was no recurrence 7 months after the operation.
