[Primary renal hemangiosarcoma. Case report and review of the literature].

Primary hemangiosarcoma of the kidney is a very rare tumor for which only 23 case reports appear in the literature worldwide. An additional case of renal angiosarcoma in an adult is reported. The patient developed local tumor recurrence with multiple metastases within 4 weeks and died although there was no evidence of metastases at the time of nephrectomy.

[Solitary metastasis to the head of the pancreas in hypernephroid carcinoma].

Metastatic renal cell carcinoma is a major cause of cancer death. Most metastases occur within the first three months after diagnosis of the primary. Solitary metastases at unusual sites are not untypical, and therefore require particular attention.
