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...

Peripheral ossifying fibroma is a benign neoplasm that usuallydevelops from gingiva, presenting as an exophytic smooth surfaced pink or red nodular mass that is sessile or is less frequently seen on a pedicle. From the Indian perspective, it is usually noticed in 5th-6th decades of life with female predilection. Microscopically, the tumour shows stratified squamous epithelium and highly cellula...

BACKGROUND Giant cell fibroma (GCF) is a distinct type of fibroma with characteristic large, stellate mononuclear or multinucleated giant fibroblasts; the stroma of GCF is relatively unexplored. The Picrosirus red polarizing microscopy technique is used to characterize the collagen fibers. The aim of this study was to evaluate the staining properties of collagen fibers in GCF and to correlate i...

Desmoplastic fibroma is a rare benign primary bone tumor that is histologically similar to the soft tissue desmoid tumor. It most often involves the mandible, large long bone or iliac bone. Desmoplastic fibroma in a toe has been extremely rarely reported. Authors report a rare case of desmoplastic fibroma of bone occurring in the distal phalanx of a foot, with descriptions of the radiographic a...

Localized gingival growths are one of the maximum regularly encountered lesions within oral cavity, which taken into consideration to be reactive as opposed neoplastic. Those encompass pyogenic granuloma, inflammation fibroma, peripheral large cellular and ossifying fibroma (POF). Among those lesions, Peripheral Ossifying Fibroma (POF) is an occasionally happening non-neoplastic growth with reg...
