J Pediatr Hematol Oncol. 2015 May;37(4):e268-71. doi: 10.1097/MPH.0000000000000313.

Abstract

Angiomatoid fibrous histiocytoma (AFH) is a soft-tissue tumor of low-grade malignancy and uncommon metastatic behavior. In this study, we describe the clinical findings of a metastatic case of AFH in the pelvis. In addition, we characterize 16 patients in the literature with AFH who metastasized over the last 4 decades. The time of appearance of metastases varied substantially and was reported 5 months to 16 years after primary tumor resection. Nine patients metastasized to lymph nodes. Excision of metastatic lymph nodes was usually curative. Pulmonary metastases were associated with fatal outcome. Long-term monitoring should be considered in patients with AFH.
