Chondromyxoid fibroma is a rare benign bone tumor. The etiology of chondromyxoid fibroma is still unknown. We report a case of a 26-year-old male who suffered from chronic cough for a year. His chest radiograph showed a lobulated tumor over the left seventh rib. The computed tomography (CT) examinat ion further revealed an osteolytic tumor arising from the left seventh rib with calcified matrix...

juvenile ossifying fibroma (jof) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (trjof) and a psammomatoid juvenile ossifying fibroma (pjof). psammomatoid variant is predominantly a craniofac...

detected in several cases [4]. In our case, immunohis-tochemical staining for vimentin was not performed. Positivity for vimentin implies that the tumor cells are of fibroblastic lineage. However, we were able to determine that with the satellite to spindle shape of cells. Histopathologically, the tumors appear well-mar-ginated under low-power microscopic examination. The tumor cells are relati...

Central cementifying fibroma is a rare non odontogenic tumor coming in the group of fibro osseous lesion, arising from periodontal ligament and is usually seen in tooth bearing area. It can affect both the mandible and the maxilla, particularly the mandible. This bone tumour consists of highly cellular, fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum o...

Nuchal-type fibroma, initially described in 1988 by Enzinger and Weiss, is a rare clinical entity associated with distinct subcutaneous and dermal fibrous tissue proliferation. The etiology of nuchal-type fibroma largely remains to be elucidated. Typical characteristics of this entity include hypocellular, haphazardly arranged collagen with entrapped adipose tissue, paucity of elastin and entra...

Twelve neonate calves were repeatedly challenged with bovine papilloma virus. All calves were initially susceptible to bovine papilloma virus and complete resistance to challenge occurred after the onset of fibroma regression. Fibroma regression was not correlated with serum antibody titers to bovine papilloma virus as measured by an immunodiffusion assay. Fibroma regression occurred prior to t...

Juvenile ossifying fibroma considered as a variant of ossifying fibroma by some authors is rare. Its aggressive behavior necessitates early detection and proper surgical management. It may mimic different pathologic entities of jaw at different stages. A case report of juvenile aggressive ossifying fibroma in a 12-year-old girl which was diagnosed, investigated and treated successfully is prese...

Desmoplastic fibroma, which develops predominantly in long bones and the mandible, is a rare and benign but locally aggressive tumor. Desmoplastic fibroma of the cranium is extremely rare. We report a case of desmoplastic fibroma of the frontal bone in a young man. Because of its locally aggressive behavior, complete surgical excision with a safety margin is essential.

This report describes a chondromyxoid fibroma of the second metacarpal bone in a 32-year-old female patient. Chondromyxoid fibroma is a rare, benign, slow-growing bone tumor of cartilaginous origin. Tumor has a high recurrance rate. Our aim was to show successful treatment of a metacarpal chondromyxoid fibroma with wide resection and implantation of finger join endoprosthesis.

Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofac...
