Gravidarum granuloma associated to an osseointegrated implant: case report

Introduction: Pyogenic granuloma, known as gravidarum granuloma or pregnancy granuloma, is a benign non-neoplastic reactive oral lesion that may occur in pregnant women. It is usually a highly vascularized mass, which has exophytic characteristics, and it may be sessile or pedunculated. Its surface has usually a smooth or lobular aspect, with its coloration ranging from red to pink. The pain sensitivity will depend on the degree of injury involving the traumatic lesion, but it is frequently painless. Adjacent areas to dental implants are rare for the appearance of this type of granuloma.Objective:The aim of this case report was to present a clinic case of gravidarum granuloma in the region of lower lingual gingiva, adjacent to an osseointegrated implant in a 33-year-old woman, with 3 months of gestation, who had the lesion since the beginning of her pregnancy.Conclusion: Gravidarum granuloma was diagnosed in association to a dental implant, and it highlights the necessity for improvements of oral hygiene in the peri-implant regions. Surgical treatment with excisional biopsy plus hygiene control were enough to settle the case.引言：化脓性肉芽肿（Pyogenic granuloma），又称妊娠性肉芽肿（gravidarum granuloma）或妊娠肉芽肿（pregnancy granuloma），是一类良性非肿瘤性反应性口腔病变，好发于妊娠期女性。该病变通常为高度血管化的外生性肿物，可呈无蒂或带蒂形态；其表面多光滑或呈小叶状，颜色从红色至粉红色不等。疼痛敏感度取决于病变受创伤累及的损伤程度，但该病变大多无疼痛感。牙种植体周围区域出现此类肉芽肿的情况较为罕见。目的：本病例报告旨在报道1例33岁、妊娠3个月的女性患者病例：其下颌舌侧牙龈毗邻骨整合种植体（osseointegrated implant）区域出现妊娠性肉芽肿，该患者自妊娠初期便出现该病变。结论：最终确诊为与牙种植体相关的妊娠性肉芽肿，该病例凸显了改善种植体周围区域口腔卫生的必要性。通过切除活检联合口腔卫生管控的手术治疗，成功治愈该病例。
