Atypical Peripheral Ossifying Fibroma of the Mandible

Peripheral ossifying fibroma (POF) is a benign localized lesion originating from gingival and alveolar oral mucosa. Its origin can be cells of periodontal ligament. The lesions usually develop in women in their twenties. POF is a complex clinical and histological diagnosis due to its shared characteristics with many other conditions. In this paper, we presented a case of an atypical peripheral ossifying fibroma (POF) in the left lateral part of the mandible in a 70-year-old male patient who had two semicircular bridges supported on four implants in the upper and lower jaws. A review of CBCT and orthopedic imaging showed no visible intraosseous changes. Histological analysis revealed the diagnosis of POF. The case in question is interesting, as elaborated on in the discussion section of this paper because POF is usually found in female patients aged between 20 and 30 years.

Giant peripheral ossifying fibroma with coincidental squamous cell carcinoma: a case report

Background Peripheral ossifying fibroma is an inflammatory or reactive hyperplasia of the gingiva that is usually small. It is formed by hard tissue in fibrous tissue, and the name “neoplastic lesion” has tended to be used frequently in Europe and America. Clinically, peripheral ossifying fibromas are painless, solitary, exophytic, sessile, or pedunculated and more frequently found in females than in males. To the best of our knowledge, there have been no reports of malignant cases. We herein report the case of giant peripheral ossifying fibroma with squamous cell carcinoma. Case presentation The patient was an 83-year-old Japanese woman who visited our hospital with a gingival massive mass. She was referred to us for an examination and treatment because it was difficult to perform tracheal intubation for surgery of sigmoid colon cancer at another hospital. The mass measured 83 × 58 × 35 mm, and it protruded to the extra-oral region from the right maxillary premolar alveolar region. Panoramic X-ray revealed the shadow of the mass in the right maxillary premolar region, which included some hard tissue. Computed tomography showed scattering calcified images in the mass. Magnetic resonance imaging was not performed because she had vertebral artery clips and screws in her forehead. Given the above findings, we performed a biopsy under local anesthesia. However, we were unable to diagnose absolutely whether the dysplastic squamous epithelia were pseudocarcinomatous hyperplasia of the gingiva or well-differentiated squamous cell carcinoma. Therefore, tumor resection was performed under general anesthesia. The histopathological diagnosis was peripheral ossifying fibroma with coincidental squamous cell carcinoma. There have been no signs of recurrence during follow-up as of 2 years after surgery. Conclusions The etiology of giant peripheral ossifying fibroma with squamous cell carcinoma is still not definite. Therefore, careful observation is necessary. It needs to be examined by accumulation of more cases in the future. We herein report the case of giant peripheral ossifying fibroma coincidental squamous cell carcinoma.

Peripheral ossifying fibroma: A case report

Localized inflammatory or reactive overgrowths are quite more common clinical findings on human gingiva. Most of the lesions are benign and innocuous though some have potency to transfer in to a malignant lesion. These types of lesions are difficult to identify clinically as their appearance are quite similar so only Histopathological evaluation can detect their identity. In this case report we displayed a case of Peripheral Ossifying Fibroma in maxillary anterior tooth region in 32 year old female patient along with clinical, Histopathological evaluation along with present and future treatment details. Peripheral ossifying fibroma (POF) is usually a fibromatic, non neoplastic enlargement of the gingiva which shows areas of calcification or ossification. Synonyms for POF include Peripheral cementifying fibroma, Peripheral fibroma with calcification, Calcifying or ossifying fibrous epulis and Calcifying fibroblastic granuloma.

An Unusual Presentation of Peripheral Ossifying Fibroma in an Elderly Male - A Case Report

Peripheral ossifying fibroma (POF) is a reactive process of the gingiva that develops due to irritation or minor trauma. Females are more affected than males suggesting a hormonal influence. This case report describes a case of peripheral ossifying fibroma in a 48-year-old male patient in 33, 34 regions in contrast to its common occurrence in young females. Histopathological examination is necessary to confirm the diagnosis. Surgical excision is the treatment of choice to prevent recurrence. One year follow up of the case showed no signs of recurrence. Gingival overgrowth is a common feature of the various types of gingival disease in the oral cavity. Gingival diseases and conditions can be due to genetic disorder, specific infections, inflammatory and immune conditions and lesions, reactive processes, neoplasms, endocrine, nutritional, and metabolic diseases, traumatic lesions and gingival pigmentation.1 Reactive processes are non-neoplastic nodular swellings that develop in response to local irritation or minor trauma. The term epulis is exophytic processes confined to the gingiva.2 Kfir et al. classified epulides into fibrous epulis, peripheral ossifying fibroma, pyogenic granuloma (vascular epulis), peripheral giant cell granuloma (or central).3 Ossifying fibromas in the oral cavity can be classified into central and peripheral type. The central type expands from the medullary cavity of the bone, arising from the endosteum or the periodontal ligament (PDL) adjacent to the root apex. Peripheral type arises from the soft tissues overlying the alveolar process which is contiguous with the periodontal ligament. 4 This article presents a case of POF in a male patient.
