Ameloblastic fibroma (AF) is an uncommon benign odontogenic tumour, with both epithelial and mesenchymal neoplastic proliferation. It occurs most frequently in the posterior region of the mandible, while its occurrence in the maxilla is extremely rare. They are usually encountered in children, emphasizing it as an important diagnostic consideration. Herein, we report the first case of a bilater...

A 40-year-old Caucasian, the otherwise healthy male patient, presented with 3-years history of a prominent tumor-like formation, located on his back, without subjective complaints. Initially, the lesion was 1-2 cm in size but gradually increased to a visible-pronounced tumor-like formation. No other dermatologic diseases, neither other known abnormalities were reported for the medical and famil...

The peripheral ossifying fibroma, a benign gingival overgrowth, occurs mainly in the anterior portion of the maxilla in young adults. The size of the lesion is usually less than 1.5 cm. We report a case of peripheral ossifying fibroma overlying the mandibular alveolar ridge of a 55-year-old female. MR scans showed a large exophytic soft tissue mass overlying mandibular alveolar ridge. The tumor...

Nuchal-type fibroma is a rare, benign, fibrous, tumor-like proliferation characterized by dense hypocellular bundles of collagen, with sparsely scattered fibroblasts, interspersed fat tissue, and entrapped nerve fibers. It usually develops in the posterior neck as a solitary, firm, poorly circumscribed, subcutaneous mass. Herein, we report about a 32-year-old man who presented with a 6-year his...

The gingiva is frequently the site of localised growths that are thought to be reactive rather than neoplastic. Many these lesions difficult identify clinically and can only identified as a distinct entity based on typical consistent histomorphology. One such lesion peripheral ossifying fibroma. It has been described using various synonyms arise from periodontal ligament, which accounts for app...

Among various types of gingival enlargements, Peripheral ossifying fibroma (POF) is a rare entity, which is nonneoplastic in nature and arises due to trauma, plaque, calculus, restorations and dental appliances. The term peripheral ossifying gingival growth was coined by Eversole and Rovin. Various synonyms are used for this gingival growth, like peripheral cementifying fibroma, ossifying fibro...

desmoplastic fibroma is a rare, locally aggressive, benign lesion. a case of desmoplastic fibroma of left side of mandible is reported. the lesion presented as painless mass in left posterior portion of mandible of a 7-year-old girl. histologically the lesion was composed of interlacing fascicles of benign appearing fibroblast in a varying ground substance of collagenous tissue. in this report,...

Verna, John E. (University of Minnesota, Minneapolis). Cell-culture response to fibroma virus. J. Bacteriol. 89:524-528. 1965.-Three established rabbit cell lines (Minnesota CRP, RbK, and RbH) were infected with Shope's rabbit fibroma virus (Patuxent strain). The responses of the cell lines to virus infection differed from one another. Minn. CRP cells produced plaques (1 to 2 mm) on the 4th or ...

Cemento-ossifying fibromas are benign tumors, and, although cases of an aggressive type have been reported, no cases of cemento-ossifying fibroma transforming into osteosarcoma have been documented previously. Low-grade osteosarcoma is a rare type of primary bone tumor, representing 1%-2% of all osteosarcomas. A 45-year-old female patient was diagnosed with cemento-ossifying fibroma, treated wi...

The clinical and pathological features of six cases of desmoplastic fibroma of bone are presented. Desmoplastic fibroma is rarely seen as a primary tumour of bone; when it does occur the sites of predilection are the long bones, but other sites such as the scapula and os calcis can be involved. Radiographically the lesion tends to expand the bone from within; it is well-demarcated and lytic, of...
