妊娠後期に発症した鼻腔内化膿性肉芽腫の1例

A pyogenic granuloma of the inferior turbinate during pregnancy

Ⅰ．はじめに

　化膿性肉芽腫は皮膚や粘膜に発生する炎症細胞の浸潤や毛細血管の増生を伴った隆起性病変である。良性疾患だが易出血性で急激に増大するため悪性疾患との鑑別を要することもある。妊娠中にしばしば発生し，妊娠を契機に発生した際には妊娠性腫瘍とも呼ばれているが，その多くは口腔内に発生し鼻腔内での報告例は少ない。今回妊娠後期に急激に発症した鼻腔内化膿性肉芽腫の1例を経験したので，文献的考察を含め報告する。

　Pyogenic granuloma is benign vascular proliferation which may occur in various part of the skin or mucosa. A 27-year-old woman presented with a mass in the left nasal cavity in the 37^th week of her pregnancy. She had one-week history of epistaxis and nasal obstruction. After delivery of a baby, excision of the lesion was performed 37-days postpartum. The bed of the granuloma was coagulated by argon plasma, and no recurrence has been recognized until 17 months after the surgery.
