Infantile fibrosarcoma in the mandible: case report

Infantile Fibrosarcoma of the Tongue Base

Infantile fibrosarcoma is an uncommon soft tissue tumour in infants and children mostly located in the extremities. Its occurrence in the head and neck, particularly in the oral cavity is extremely rare. Here, we report a case of infantile fibrosarcoma of the tongue base in a 9-year-old boy and discuss the complexities in arriving at diagnosis and its management. The patient underwent wide local excision of the tumour. Histopathology was essential in confirming the diagnosis. As per search in English literature, this is the first case of infantile fibrosarcoma of the tongue base to be reported till date. Treatment of choice is wide local excision with or without chemotherapy.

Recurrent adult-type fibrosarcoma of the frontal bone in a child

INTRODUCTION

Primary, adult-type bone fibrosarcoma is an uncommon, malignant spindle-cell tumor of fibroblastic origin, rarely affecting children. Most frequently diagnosed among bone malignancies in the past, improved diagnostic techniques and further restrictive classification criteria have currently made the diagnosis of fibrosarcoma very unusual.

CASE REPORT

We hereby report the case of a 7-year-old child with a right frontal swelling mass. A computed tomography scan showed an osteolytic lesion of the right frontal bone, involving the diploe and the outer table of the skull. An en bloc surgical excision, followed by a thorough immunohistological evaluation, led to the diagnosis of fibroblastic proliferation, with low cellularity and minimal atypias. The patient had four recurrences during the 4-year follow-up. With an increasing histological grade at recurrences, a diagnosis of adult-type fibrosarcoma was made.

CONCLUSION

To the best of the authors' knowledge, this is the first reported case of an adult-type fibrosarcoma arising in the frontal bone of a child.

Primary fibrosarcoma of maxilla in an 8-year-old child: A rare entity

Fibrosarcoma (FS) is a malignant mesenchymal neoplasm of the fibroblasts that is uncommon in the head and neck and constitutes less than 1% of malignancies and approximately 6% of the soft tissue sarcomas. FSs rarely occur before the third decade except infantile type. This condition primarily affects long bones, and its occurrence in the cranium is rare (15%), with the mandible being the most commonly involved cranial site. Here a case of primary FS in anterior maxilla of an 8-year-old male child is reported. This article is presented to document the rarity of FSs in the jaws of children with review of literature.

A rare case of fibrosarcoma of the jaws in a 4-year-old male

A case of fibrosarcoma in a 4-year-old male child is reported. Primary fibrosarcomas of bone in the head and neck region are rare. The histological appearance of the tumour is related to its grade of differentiation. It could present a high level of cellularity and the amount of collagen is variable. The accepted treatment is radical surgery; however, metastases could occur in the lungs. This article is presented to highlight the rarity of fibrosarcomas in the jaws of children.

Fibrosarcoma in children--a rare tumour with long-term survival even with advanced disease--a report of 3 cases

Fibrosarcoma is a rare tumour in children. The potential of malignancy has been questioned. We present three cases of fibrosarcoma in children . The follow-up periods range from 10 to 37 years. The first patient had pulmonary metastases at the time of diagnosis in 1958. The primary tumour in fossa ischio-rectalis was resected in 1960. Lung metastases were resected in 1960 and 1989. Radiotherapy was given in 1992. He is still alive with metastases 37 years after the first manifestation of disease. The second patient had a primary tumour and several local recurrences in the mandible. He is alive without evidence of disease 4 years after resection of pulmonary metastases and 21 years after resection of the primary tumour. The third patient has no signs of recurrence or metastatic spread 10 years after a wide excision of subcutaneous tumours of the left upper arm. The cases demonstrate a special tumour-entity of low-grade malignancy, which show a good prognosis and a wide spectrum of biological behaviour.

Juvenile fibrosarcoma of the temporal bone

A case of juvenile fibrosarcoma arising from the head and neck region is described. This type of tumour should be considered as a separate entity different from the fibrosarcoma in adults because of the different clinical behaviour. The symptomatology, the radiographic features and the literature data are reviewed.

Ameloblastic fibrosarcoma

A case of an ameloblastic fibrosarcoma in the mandible is described. The primary tumor was seen in a 5-year-old child. In spite of repeated surgical interventions, the tumor recurred three times within a one and a half year period, but not metastases have been observed. The difficulties in arriving at a correct diagnosis for this rare tumor involving the mandible are discussed. The treatment of choice seems to be radical surgery.
