JOURNAL OF ORAL & MAXILLOFACIAL RESEARCH Epivatianos et al. Myofibroblasts and Transforming Growth Factor-Beta1 in
2016Co-Authors: Reactive Gingival Overgrowths, Apostolos Epivatianos, Dimitrios Andreadis, Savas IordanidisAbstract:Objectives: The aim of this study was to detect the presence of myofibroblasts and transforming growth factor-beta1 in fibrous and ossifying-fibrous Epulis and their possible contribution to the collagenous connective tissue formation. The correlation between the myofibroblasts and the degree of inflammatory infiltration was also examined. Material and Methods: The presence of myofibroblasts as well as transforming growth factor-beta1 was examined in twenty cases of fibrous Epulis and 22 ossifying fibrous Epulis, using immunohistochemistry. Results: Myofibroblasts positive for alpha smooth muscle actin and vimentin but negative to desmin were found in 20 % and 45 % in fibrous Epulis and ossifying fibrous Epulis, respectively. Myofibroblasts were distributed in areas with and without inflammatory infiltration and their presence in inflammatory areas was not related with the degree of inflammatory infiltration. A percentage of 21- 60 % of fibroblasts and chronic inflammatory cells expressed transforming growth factor-beta1 in all cases. Conclusions: These data suggest that transforming growth factor-beta1 and myofibroblasts contribute to the formation of collagenous connective tissue in fibrous Epulis and ossifying fibrous Epulis. Myofibroblasts are mainly presented in ossifying fibrous Epulis than in fibrous Epulis. It seems to be no relationship between the presence of myofibroblasts and the degree o

It seems to be no relationship between the presence of myofibroblasts and the degree of inflammatory infiltration of the lesions.

Prenatal diagnosis of congenital Epulis. A case study.
Fetal diagnosis and therapy, 2006Co-Authors: V. Thoma, B. Idrissi, M. Kohler, F. Becmeur, B. Viville, Romain FavreAbstract:Congenital granular Epulis is a rare benign tumour situated on the alveolar ridge, which usually presents as a single tumour of variable size. Prenatal diagnosis of Epulis has rarely been reported in medical literature. A possible complication is airway obstruction, which is essentially determined by the size of the tumour. Because of the potential risk of neonatal respiratory distress, prenatal diagnosis is valuable in the organization of a safe delivery. The case presented here is the prenatal diagnosis of a congenital Epulis discovered in the 32nd week of pregnancy.

prenatal diagnosis of congenital Epulis a case report
Ultrasound in Obstetrics & Gynecology, 2002Co-Authors: Masahiko Nakata, K Anno, L T Matsumori, Masahiro Sumie, Masakatsu Sase, T Nakano, Hirotaka Hara, Yuji Imate, Yasuhiko Nakamura, Hiroshi KatoAbstract:Congenital Epulis or congenital granular cell tumor, is a benign tumor that has rarely been diagnosed prenatally. We report a case of a large congenital Epulis diagnosed at 26 weeks of gestation that increased in size during gestation. Color and power Doppler ultrasound examination showed marked blood flow in the tumor. The tumor could be resected completely following Cesarean section and histologically examined. We discuss the prenatal diagnosis and histogenesis of congenital Epulis.
