Peripheral odontogenic fibroma (POdF) is a rare benign odontogenic neoplasm. mucosal

Peripheral odontogenic fibroma (POdF) is a rare benign odontogenic neoplasm. mucosal analog to the central odontogenic fibroma.[2] Cases reported in the literature under the terms odontogenic gingival epithelial harmartoma hamartoma of the dental lamina and peripheral ameloblastic fibrodentinoma are actually examples of POdF.[1,3] They are rare and comprise only 0.05% of all biopsy specimens, but they are the most common peripheral odontogenic tumor. The ratio of occurrence of the central to peripheral odonrtogenic fibroma is 1.4:1.4. About 207 cases are reported in the English literature with follow-up information on 31 cases. An extremely inadequate data for the biologic recurrence and behavior of the lesion exists. POdF is highly recommended a combined odontogenic tumor since it comprises energetic odontogenic epithelial and ectomesenchymal parts. It’s been mentioned that budding from the basal cell coating of the top squamous epithelium was connected EX 527 enzyme inhibitor with higher recurrence. The current presence of calcification in immediate apposition to epithelial rests was connected with lower recurrence.[4] The goal of this informative article is to record the clinical and histopathological top features of an instance of POdF inside a 53-year-old man individual who exhibited recurrence. Case Record A 53-year-old man patient reported using the complaint of the painless bloating on spine tooth area since six months. Individual gave a brief history of identical swelling 12 months back that he previously undergone excision in an exclusive clinic, no additional records was from the patient regarding the same. On intraoral examination, a localized, sessile, erythematous growth was present in the maxillary alveolar region of size 3 cm 2 cm, extending from buccal gingiva of 15-16 [Figure 1] to the palatal gingiva of EX 527 enzyme inhibitor 15-16 by traversing the interdental papilla [Figure 2] with mild tooth displacement. The swelling was firm, nontender and exhibited bleeding on palpation. The periodontal examination revealed generalized periodontitis with the recession and Grade II mobility. No other relevant medical and family history was given by the patient.

The gross specimen was greyish white, nodular, firm, measuring about 2.5 cm 2 1.7 cm. A gritty texture was felt on sectioning. The hematoxylin and EX 527 enzyme inhibitor eosin stained section of the specimen under the light microscope exhibited stratified squamous parakeratinized surface epithelium associated with a fibromyxoid connective tissue. The surface epithelium exhibited slender, branching, and deep Rabbit Polyclonal to STAT5B penetrating rete ridges with budding. The sub-basilar connective tissue showed abundant capillaries [Figures ?[Figures33 and ?and44].

The sub-basilar connective tissue showing abundant capillaries Open in a separate window Figure 4 Surface epithelium exhibiting slender, branching, deep penetrating rete ridges with basal cell budding. The sub-basilar connective tissue showing abundant capillaries Islands and strands of odontogenic epithelium were found to be scattered throughout the connective tissue [Figure 5], which was more cellular in the fibrous areas [Figure 6] than the myxoid areas [Figure 7]. Few foci showed cementoid and osteoid calcifications [Figure 8]. Considering these features, the case was finally diagnosed as POdF with a comment on its chances to recur.

Commonly given differential diagnosis of peripheral swellings are PG, POF, PGG, peripheral ameloblastoma, parulis, POdF, and fibroma.[1] Treatment Oral prophylaxis was done and a complete surgical excision of the lesion was performed. The patient was advised for a periodic follow-up. Outcome and follow-up Our patient exhibited recurrence.
