RESUMEN
Soft-tissue sarcomas are uncommon and heterogeneous tumors of mesenchymal origin. A soft-tissue mass that is increasing in size, greater than 5 cm, or located under deep fascia are criteria for suspicion of sarcoma. Diagnosis, treatment, and management should preferably be performed by a multidisciplinary team in reference centers. MRI and lung CT scan are mandatory for local and distant assessment. A biopsy indicating histological type and grade is needed previous to the treatment. Wide surgical resection with tumor-free tissue margin is the primary treatment for localized disease. Radiotherapy is indicated in large, deep, high-grade tumors, or after marginal resection not likely of being improved with reexcision. Neoadjuvant and adjuvant chemotherapy improve survival in selected cases, usually in high-grade sarcomas of the extremities. In the case of metastatic disease, patients with exclusive lung metastasis could be considered for surgery. First-line treatment with anthracyclines (or in combination with ifosfamide) is the treatment of choice. New drugs have shown activity in second-line therapy and in specific histological subtypes.

Angiosarcomas account for 2% of all soft tissue sarcomas and of them, primary renal angiosarcomas represent 1%. Twenty-four cases have been published in the English specialised literature. We report the second case to be described in a middle-aged female, with pulmonary metastases at diagnosis, and fatal outcome despite surgery and chemotherapy.

Kaposi's sarcoma (KS) is characterised by proliferation of vascular endothelial and lymphoreticular cells, frequently with a multicentric expression developed from a single node and evolving to multiple cutaneous lumps or plaque-like appearance. Four types of KS with similar histological patterns have been described in terms of their clinical and epidemiological features: classic KS, endemic (African) KS, iatrogenic KS and epidemic (AIDS-related) KS. The differences in clinical features are quite relevant: classic KS is usually limited to the lower extremities; whereas immunodeficiency-related diseases frequently involve several organs. A case of a 67-year-old woman with metastatic KS and unproven immunodeficiency is presented.
