A 14-year-old girl was diagnosed with alveolar soft part sarcoma (ASPS) of the thigh and lung metastases. She underwent tumor resection and pulmonary metastasectomy followed by hyperfractionated local radiotherapy (44.8 Gy). A mesh graft transplant was used to cover the postoperative skin defect on the thigh. Since ASPS do not respond to conventional chemotherapy antiangiogenic treatment with peginterferon alfa-2b and thalidomide was started. Immunohistochemical analysis of tumor tissue showed expression of vascular endothelial growth factor receptors (VEGFR) 1, 2, 3, and platelet derived growth factor receptor (PDGFR)-alpha and -beta. Hence, additional treatment with multitargeted receptor tyrosine kinase inhibitor sunitinib (Sutent) was started on a compassionate use basis. 2 weeks later the patient presented with necrosis of the skin transplant requiring necrectomy and skin grafting. This case illustrates that drugs inhibiting vascular endothelial growth factor receptors have to be used very cautiously in cancer patients with severe pre-existing skin damage.
