Large, atypical peripheral ossifying fibromas are known as giant peripheral ossifying fibromas. These lesions have often been associated with heterogeneous clinical and radiographic characteristics subsequently leading to their misdiagnosis. Biopsies have been the gold standard for the diagnosis of such lesions. This study reports on an acute presentation of giant peripheral ossifying fibroma, ...

Although ossifying fibroma (OF) is a slow growing neoplasm, some lesions may behave aggressively, reaching massive proportions that may demand special treatment. Synchronous presentation of this lesion in the maxilla and mandible is a rare occurrence. A case is presented of a 27-year-old woman who manifested synchronous OF lesions in the left maxilla and right mandible. The clinico-radiologic a...

Background: There is an array of clinically and academically derived opinion as to the correct surgical approach to the intermetatarsal space, most frequently to excise a symptomatic interdigital perineural fibroma (aka Morton’s Neuroma). The purpose of this retrospective case series was to evaluate the patient outcomes, and sequelae following a longitudinal plantar incision for excision of int...

A 1-year-old male thoroughbred racehorse experienced swelling of the left upper lip. The swelling was attributable to enlargement around the incisive bone of the interdental space posterior to the third incisor in the left maxilla. Even after two operations to reduce the bulk of the mass, it continued to increase in size. Dyspnea caused by stenosis of the nasal cavity forced us to perform eutha...

BACKGROUND Fibro-osseous lesions of the jaws, including juvenile ossifying fibroma, pose diagnostic and therapeutic difficulties due to their clinical, radiological and histological variability. The aim of this study was to report the outcome of a 9 years old girl with diagnosed juvenile ossifying fibroma treatment. METHODS A 9 years old girl presented with a 6 x 8 cm sized hard fixed tumour ...

Fibroma of tendon sheath, which is a benign soft tissue tumor, primarily affects the finger, hand, or wrist. It rarely involves the knee and only a few cases appear in the literature. Here, we report a case of fibroma of tendon sheath on the medial side of the knee, in a previously hardly reported location, and provide detailed imaging and histological findings. A 54-year-old man presented with...

In the preceding two papers (1, 2) we have described aberrant strains of rabbit fibroma virus, a virus which normally gives rise to fibroma-like growths at the site of inoculation in cottontail or domestic rabbits (3). Those chiefly studied were derived from a growth in one cottontail rabbit (A); the strain in its original form is designated "original fibroma virus," fibromatous virus or OA str...

Ossifying fibroma is benign, uncommon, monostotic well defined usually unilocular but occasionally multilocular fibroosseous tumor, arising from the cells of periodontal ligament and is composed of fibrous connective tissue with variable amounts of calcified tissue resembling bone, cementum or both. It is generally an asymptomatic, slow growing lesion, found in 2nd to 4th decades of life at the...

Chondromyxoid fibroma is an unusual benign tumor of cartilaginous tissues that may be confused with other some malign tumors. It is rarely seen in the skull. A 45-year-old female was admitted with painless bony swelling in the forehead. Computerized tomography demonstrated a well-defined expansive lesion with a sclerotic margin measuring approximately 3 cm in diameter in the right frontal bone....

This report contains a statistical review of 559 cases of lesions forming hard tissues that were diagnosed by the departments of Clinical Pathophysiology and of Pathology at Tokyo Dental College from 1966 to 2001. Sixteen kinds of lesions which were related to the formation of bone, cartilage or cementum were analysed: osteoma, osteo-chondroma, chondroma, osteoid osteoma, osteoblastoma, ossifyi...
