Context: Treatment of Fibroblastic and Myofibroblastic Tumors / Infantile Fibrosarcoma
Infantile fibrosarcoma usually occurs in children younger than 1 year. This tumor usually presents with a rapidly growing mass, often noted at birth or even seen in the prenatal ultrasound. The tumors are frequently quite large at the time of presentation.[82] Hypercalcemia secondary to elevated levels of parathyroid hormone–related protein has been reported as a presenting feature of this disease in newborns.[83]
These tumors have a low incidence of metastases at diagnosis.
