Desmoplastic fibroma is one of the uncommon osseous tumors that present in the skull. Although classified as benign tumor, desmoplastic fibroma exhibits local aggressiveness and has a high potential for recurrence. The most common sites include metaphysis of long bones and mandible. Only 15cases have been described in the skull. We report the 16th case of desmoplastic fibroma of the skull.

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.

Skeletal desmoplastic fibroma is an intraosseous neoplasm that is recognized as a very scare benign tumor. It has a propensity for locally aggressive behavior and local recurrence. The aim of this article is to report a case of skeletal desmoplastic fibroma in right mandible of a 4-year-old boy. The patient was found to have a large skeletal desmoplastic fibroma in right mandible, which was resected by surgical intervention. The defect was successfully restored with a titanium plate. In the report, the etiopathogenisis, pathological, radiographic features, clinical diagnosis, therapy and prognosis of skeletal desmoplastic fibroma were diccussed.

Desmoplastic fibroma is a rare, benign intraosseous fibroblastic tumor, which is locally aggressive. It is osseous counterpart of soft tissue fibromatosis. The authors experienced the patient who complained persistent mouth opening limitation with mild swelling on the left mandibular angle area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed as desmoplastic fibroma of the mandible. The results were as follows: 1. Main clinical symptoms were mouth opening limitation which had been persistent for 9 months and mild swelling on the left mandibular angle area. 2. Radiographs showed the radiolucent lesion and expansion of lingual cortex. CT finding is homogeneous soft tissue mass with expansion of left mandibularramus. Destruction of medial wall of ramus and invasion to adjacent soft tissue is also seen. 3. Histopathologically, plump spindle shaped fibroblasts arranged in bundles or fascicles are observed. The cells of tumor are infiltrating into muscle fiber with destruction of bony trabeculae and merged with surrounding salivary gland.

Desmoplastic fibroma of bone is an extremely rare tumor that was first described by Jaffe in 1958. It histologically resembles the desmoid tumor of soft tissue. It is known as locally aggressive tumor but we experienced definitely benign and resembling simple bone cyst radiographically. We report a case of desmoplastic fibroma of bone and it should be included in the differential diagnosis list of any lytic bone lesion. The radiograph, MR imaging features, radiological and pathological differential diagnosis of the case are described, and literatures are reviewed.

A Collagenous Fibroma (Desmoplastic Fibroblastoma) is a rare, benign, slowly growing, fibroblastic, soft tissue lesion. Here, the case of a 28-year-old woman, who presented with a 1-year history of a slowly growing painless mass in the right anterior aspect of her neck, is described. This type of tumor was first described by Evans in 1995, and named as a Desmoplastic fibroblastoma but was renamed, by Nielsen in 1996 as a Collagenous Fibroma. This type of tumor is frequently reported in men with a mean age at occurance of 50 years. Clinically, a Collagenous fibroma presents as a firm, well-circumscribed subcutaneous, or intramuscular, painless mass of long duration. They are mostly located in the neck and extremities. The tumors range in size from 1 to 20 cm and predominantly occurs within the subcutaneous tissue, but fascial and skeletal muscle involvement is common. The treatment of a Collagenous Fibroma is a total surgical excision. No tumor recurrence has been reported the literature during the follow-up period and no tumor recurrence was observed in our case at the 1-year follow-up.

Primary osteosarcoma of the skull is a rare finding. We report here on a pathologically proven case of osteosarcoma that presented as a painless mass in the frontal bone of a 7-year-old boy. This unusual form of osteosarcoma had features of desmoplastic fibroma in a large portion of the tumor. We also include a review of the medical literature related to osteosarcoma.
