Inflammatory pseudotumor in the mandibular retromolar region
1Department of Oral Surgery, Saitama Medical Center, Saitama Medical School, Kawagoe, Japan.
Summary
A rare oral pseudosarcomatous lesion was found in a 43-year-old woman. This aggressive lesion, diagnosed as an inflammatory pseudotumor, showed no recurrence after one year.
Area of Science:
- Oral Pathology
- Surgical Pathology
- Oncology
Background:
- Pseudosarcomatous lesions of the oral mucosa are rare and can mimic malignant tumors.
- Distinguishing these benign but aggressive-appearing lesions from true sarcomas is crucial for appropriate management.
Observation:
- A case of an unusual pseudosarcomatous lesion of the oral mucosa is presented.
- The lesion manifested as an aggressive, ulcerative mass in the mandibular retromolar gingiva.
- Histopathological examination revealed florid myofibroblastic and fibrohistiocytic proliferations with infiltrative margins.
Findings:
- The lesion was diagnosed as an inflammatory pseudotumor.
- Despite apparent incomplete excision, the patient showed no signs of disease recurrence at the 1-year follow-up.
Implications:
- This case highlights the importance of considering inflammatory pseudotumors in the differential diagnosis of oral ulcerative masses.
- Accurate histopathological assessment is key to successful management and prognosis.
- The favorable outcome in this case suggests that complete resection may not always be necessary for resolution.
