Multicentric infantile hemangiopericytoma: case report and review of the literature.

ABSTRACT

Hemangiopericytomas are rare tumors in which outcome varies with age of onset. Those developing in adults and older children tend to be aggressive with a poor prognosis. However, infantile hemangiopericytomas often behave in a more benign manner. Recent findings suggest aggressive lesions may be histogenetically distinct. Multicentric disease is exceptionally rare, but tends to occur in infants and poses a therapeutic challenge. We present a case with extensive cutaneous and intracranial involvement, which resolved spontaneously. Tumor behavior is a key consideration in management, with careful observation recommended in uncomplicated cases and intervention indicated if more aggressive growth or spread occurs.
