[Cystic neoplasms of the pancreas: a review of the literature apropos 5 cases]. / Neoplasias quísticas de páncreas: revisión de la literatura a propósito de cinco casos.

Cystic neoplasms of the pancreas make up a group of uncommon tumors. Their relevance lies upon their favorable prognosis after resection and the fact of being commonly mistaken with pseudocysts. Based on five patients treated at our hospital in the last few years we make an update review of the literature on these tumors. To note the role that imaging and puncture-aspiration techniques can play for diagnosis. We conclude that when a cystic lesion of the pancreas is found, the diagnosis of cystic neoplasm must be considered, thus avoiding delays in surgical resections which may condition the patient's prognosis.

[Gastric metastasis of renal adenocarcinoma. Presentation of a case and review of the literature]. / Metástasis gástrica de adenocarcinoma renal. Presentación de un caso y revisión de la literatura.

A case of gastric metastasis of renal carcinomas is described. The patient had been nephrectomized 22 months ago, and she had yet presented another in appearance solitary metastasis in lung and brain, which had been resected. This is a very unusual localization in the spread of a renal tumor, and two cases alone exist in the literature up to date which had been diagnosed during life. In despite of surgical treatment, a short free interval after nephrectomy and the tumor aggressivity, with three foci of spread at less than a year, have been the pivotal factors determining a relatively short survival of 26 months after resection of primary tumor.
