We report a case of cranial fasciitis in a 14-month-old boy. The lesion grew at the site of a previous head trauma, rapidly destroying the skull. Surgery disclosed that the lesion was highly vascular and adhered to the dura. Because histopathological study of a frozen section did not show malignancy, the authors decided not to perform dural excision after total removal of the lesion. No recurrence of the lesion was seen. The authors stress that this rate fibroblastic lesion must be included in the differential diagnosis of pediatric skull tumors and that careful histopathological observation is needed to avoid extensively invasive surgery.
