Primary giant congential infantile fibrosarcoma of the scalp: case report and review of literature

Abstract

Case report: A primary giant infantile fibrosarcoma of the scalp in a 6-month-old boy is reported. He presented with a rapidly enlarging right paramedian parietal scalp swelling since birth. There were no signs of raised intracranial tension. Magnetic resonance (MR) imaging of the brain revealed a large vascular scalp tumor extending over the posterior frontal and parietal region bilaterally crossing the midline. There was no intracranial extension. Carotid angiography revealed an extremely vascular tumor supplied by the external carotid artery branches. The tumor was completely resected through a curvilinear scalp incision. Histology was consistent with diagnosis of an infantile fibrosarcoma. The patient had an uneventful course and received no postoperative adjuvant therapy. MR imaging of the brain at follow-up after 5 years showed no evidence of recurrence of tumor. At follow-up after 10 years, he is asymptomatic and leading an active life.

Discussion: The pathology and management of primary scalp fibrosarcoma is discussed, and the relevant literature is briefly reviewed.
