“…IPTs have been reported in the maxillary sinus. 4,5 However, the tumor in this case was found in the maxillary bone, abutting but not involving the maxillary sinus. As a soft tissue tumor, IPTs can cause bone infiltration and destruction with a behavior highly suspicious for a malignant neoplasm.…”

“… 2 , 4 The tumor usually occurs in young adults. 5 Morphologically, the sheeting of plasma cells, in addition to the infiltrative pattern of growth, mimics plasmacytoma. Moreover, the highly reactive myofibroblasts also required pancytokeratin in our case to exclude carcinomas with single-cell patterns such as lobular carcinoma metastasizing to the bone, especially in view of the patient’s sex and the reactive fibrotic background.…”

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.
