(2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). McGraw-Hill. ISBN 0-07-138076-0.〕〔 〕 It is often found to involve the gums, the skin and nasal septum, and has also been found far from the head such as in the thigh. ==History and terminology== Pyogenic granuloma was first described in 1897 by two French surgeons, Poncet and Dor, who named this lesion ''botryomycosis hominis''.〔Ferry AP, Zimmerman LE. Granuloma pyogenicum of limbus. Arch Ophthalmol 74:229–230, 1965.〕 This name is misleading as it is not a true granuloma. In actuality, it is a capillary hemangioma of lobular subtype which is the reason they are prone to bleeding.〔 Additionally, it is also not truly ''pyogenic'', ("pus producing") as the cause is hormonal or traumatic and has no association with infection or pus production. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pyogenic granuloma」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
