Inflammatory pseudotumors are benign lesions that are rarely reported in the head and neck. Moreover, intraosseous inflammatory pseudotumors of the maxilla are extremely rare, with less than 10 cases reported. A 52-year-old woman presented with recurrent dental infections; computed tomography scan of the osteolytic maxillary bone lesion and incisional biopsy were performed. Histopathological examination revealed that the lesion was composed of fascicles of fibroblasts and myofibroblasts, in addition to sheets of plasma cells, lymphocytes, and occasional other inflammatory cells. An infiltrative growth pattern was observed. Immunohistochemical staining confirmed an inflammatory pseudotumor. A partial maxillectomy was performed. There was no evidence of recurrence during the 4-month follow-up period. Inflammatory pseudotumors should be considered when treating destructive maxillary lesions. Immunohistochemical staining was performed to confirm polyclonal plasma cell proliferation.
炎性假瘤是一种良性病变，在头颈部很少见。此外，上颌骨的骨内炎性假瘤极为罕见，报道的病例不到10例。一名52岁女性因反复出现牙齿感染就诊；对溶骨性上颌骨病变进行了计算机断层扫描并进行了切开活检。组织病理学检查显示，病变除了有大量浆细胞、淋巴细胞和偶尔的其他炎症细胞外，还由成纤维细胞和肌成纤维细胞束组成。观察到浸润性生长模式。免疫组织化学染色证实为炎性假瘤。进行了部分上颌骨切除术。在4个月的随访期内没有复发迹象。在治疗上颌骨破坏性病变时应考虑炎性假瘤。进行免疫组织化学染色以确认多克隆浆细胞增殖。
