 note = {1979年から1998年の19年間に,新潟大学歯学部附属病院小児歯科において治療した口腔軟組織の良性限局性線維性組織病変22症例について,臨床病理学的に検討し次の結果を得た。1.性別症例数は,男児9例,女児13例で,年齢は8か月から11歳4か月に分布し,1歳以下の乳児の症例が3例あった。2.発生部位は,歯肉が16例と多く,次いで口蓋4例,頰粘膜2例で,病理診断は,歯肉症例は線維性エプーリス,口蓋と頰粘膜症例は線維性過形成あるいは線維上皮性過形成であった。3.線維性エプーリス16症例は,上顎10例,下顎6例で,16例中15例が前歯部にみられた。病理組織像は,粘膜下の結合組織に膠原線維の密な増生がみられた。4.口蓋症例の4例中3例は,切歯乳頭に接して,ほぼ同部位にみられたが,切歯管との連続性はなかった。5.治療は,全例摘出術が行われ,再発症例はなかった。6.小児の口腔軟組織における線維性病変では,線維性エプーリスの頻度が高いと思われた。7.頰粘膜症例は,粘液囊胞と臨床的に診断されており,摘出物の病理組織検査は,確定診断を得るために重要である。, Fibrous lesions such as fibroma, fibrous hyperplasia, fibrous epulis, denture fibroma are not so rare in the oral cavity. There are, however, few reports about them in children. We experienced 22 cases of oral fibrous lesions at the Pedodontic Clinic of Niigata University Dental Hospital during a period of 19 years from 1979 to 1998 and investigated them clinically and histopathologically. The results were as follows: 1. The patients consisted of 9 males and 13 females. Their ages ranged from 8 months to 11 years and 4 months. Three patients were under 1 year old. 2. Sixteen cases were located on the gingiva, 4 on the palate and 2 on the buccal mucosa. They were pathologically diagnosed as fibrous epulides in 16 cases and fibrous hyperplasia or fibroepithelial hyperplasia in 6 cases. 3. As for the 16 cases of fibrous epulides, 10 cases occurred in the maxilla and 6 in the mandible. Fifteen cases were in the incisor region. All of the epulides were smaller than 1 cm in diameter. Microscopically, they were shown to be composed of numerous fibroblasts and proliferating collagen fibers. 4. As for the 6 cases of fibrous hyperplasia, four cases occurred on the palate and two on the buccal mucosa. Three of the four cases of palatal fibrous hyperplasia were similarly located near the incisor foramen. They were hemispherical or elliptical in shape, 3-7 mm in diameter, and pedunculated or sessile and elastic-hard. Buccal lesions were clinically well-defined masses with smooth, normalcolored surfaces and broad bases. They were clinically suspected of mucocele. Microscopically, the lesions were shown to be composed of proliferating collagen fibers. 5. All of the fibrous lesions were excised surgically and no recurrence was found. 6. Most of the oral fibrous lesions in children may be fibrous epulides. Histological examination of the excised specimens is needed to confirm the diagnosis.},
