Cranial fasciitis of childhood: a case report.

We present a case with cranial fasciitis in childhood and review the literature. A 7-year-old boy presented with hard mass on the scalp. He had sustained a bruise on the right temporal region about 2 years previously. Ultrasonic examination and CT scanning revealed the ossifying soft tissue mass in the right temporal scalp causing erosion and scalloping of the outer table of the skull. At surgery the lesion was firmly attached to the periosteum and the skull. The lesion was completely excised and the lytic bone curettaged. The tumor was composed of immature fibroblasts and diagnosed as cranial fasciitis in childhood. A brief review of the literature is included emphasizing the need to investigate further this completely benign lesion that is frequently confused with a malignant neoplasm.
