A 34-year-old man with a brown complexion visited the Oral Diagnosis Clinic, reporting the presence of an asymptomatic tumor on his gingiva for the past 18 months. This lesion was affecting both his speech and aesthetics. Upon intraoral examination, a well-defined, pedunculated nodule was observed in the attached gingiva of the anterior maxilla, which was covered by normal mucosa. In an effort to determine the nature of this lesion, an excisional biopsy was performed, initially with the diagnostic suspicion of a non-neoplastic inflammatory condition. Histological examination unveiled a benign mesenchymal neoplasm characterized by fusiform, oval, and stellate cells arranged in a fascicular pattern and permeated by a myxoid stroma. Immunohistochemical staining demonstrated positivity for AML and negativity for S100. With these findings taken into account, the final diagnosis was established as an inflammatory myofibroblastic tumor (IMT). IMT is a soft tissue tumor commonly observed in the lungs but is rare in the oral cavity. It can manifest with variable clinical behavior, making it a diagnostic challenge. [ABSTRACT FROM AUTHOR] |
