Recurrence of a Peripheral Ossifying Fibroma as a Pyogenic Granuloma Within 1 Week: A Case Report.

Introduction: Peripheral ossifying fibromas (POFs) and pyogenic granulomas (PGs) are non-neoplastic reactive lesions of gingiva that usually affect young females and are usually located in the anterior maxilla. It is possible to misdiagnose POF as PG, peripheral giant cell granuloma, or odontogenic tumors. Histopathologic examination is recommended and is essential for an accurate diagnosis of such lesions, and differential diagnosis is also important because POFs have a tendency to recur.

Case Presentation: A clinical case of gingival swelling in the mandibular left second premolar and first molar region on the lingual side, which was diagnosed as a POF on histopathologic examination, is reported. Recurrence of the lesion was seen within 1 week of its excision. The recurrent overgrowth was again excised, thoroughly curetted, and histopathologically confirmed as a PG. No signs of recurrence were seen at the 6-month follow-up.

Conclusion: This case shows the importance of complete excision of the lesion to the entire depth with curettage of the adjacent tissues for prevention of recurrence.
