Abstract : 「緒言」口腔と全身の関連性の研究における近年の著しい進展により, 歯科医師の名称だけでは担当領域を表現しきれなくなっており, むしろ口腔科医という方が相応しい時代となってきた. 特に口腔がん検診の取り組みは隅々まで広がりをみせており, 開業歯科医師といえども口腔がんの知識と伴に, 口腔粘膜に生じる様々な病変に対する深い理解が求められる時代となった. 日常臨床でよく遭遇する線維増殖性病変は, 口腔内でも高頻度で発生する. 1995年発表された神奈川歯科大学における非歯原性良性腫瘍の臨床統計的観察によると, 線維腫の頻度が最も多く6割を超えている. 線維増殖性病変は大きく2つに分けられる. 刺激による線維過形成からなる病変, いわゆる刺激性線維腫として, 咬傷などによる外傷性線維腫と義歯の不正刺激による義歯性線維腫がある.

Abstract : [Abstract] The oral cavity is subject to extensive external irritation and is thus susceptible to fibroproliferative lesions. Fibromas that grow in response to trauma or chronic stimulation are called irritation fibromas, which also include denture fibromas. Although irritation fibromas and neoplastic fibromas differ, they are difficult to distinguish histologically. Therefore, we compared denture fibromas with neoplastic fibromas to demonstrate histological distinctions among fibroproliferative lesions. The subjects in this study included 15 patients with neoplastic fibromas and 15 patients with denture fibromas. Fibrous tissues were characterized using Masson's trichrome staining. An enzyme-labeled antibody method was used for the immunohistochemical analysis of CD34, Bcl-2, and Ki-67 expression. Differences in mean cell counts and number of cells with positive immunohistochemical staining were analyzed using Welch's t-test. CD34 expression was high in spindle cells in denture fibromas but was absent in neoplastic fibromas. Pronounced Bcl-2 expression was observed in neoplastic fibromas. However, Bcl-2 expression was low in denture fibromas. The number of Ki-67-positive cells was significantly higher in neoplastic fibromas than in denture fibromas. Cell count results were identical. In Masson's trichrome staining, collagen fiber hyperplasia was observed more frequently in denture fibromas than in neoplastic fibromas. In conclusion, neoplastic fibromas and denture fibromas present with different histological and immunohistochemical characteristics that may be useful for distinguishing fibroproliferative lesions.
