Abscopal effect induced by cryoablation in a 55-year-old patient with metastatic dedifferentiated liposarcoma: a case report.

Background: Metastatic dedifferentiated liposarcoma (DDLPS) is primarily managed with chemotherapy, yet with poor response rate. Locoregional therapies, such as radiotherapy and percutaneous cryoablation, can provide palliation for inoperable metastatic sarcomas. In rare instances, those ablative therapies can elicit an immune-mediated regression of untreated metastases in a process named the abscopal effect.

Case Report: Tyrosine Kinase Inhibitors Induced Lymphadenopathy in Desmoid Tumor Patients.

Tyrosine kinase inhibitors (TKIs) are nowadays a valuable treatment of desmoid tumors, a rare mesenchymal neoplasm. Although many side effects of imatinib and pazopanib, commonly or rarely occurring, have been described, reactional lymphadenopathy has not yet been reported. In this publication, we report two cases of patients with desmoid tumors, treated with pazopanib and imatinib, who developed reactional lymphadenopathy.
