[Iatrogenic splenectomy in surgery of renal tumors]. / Esplenectomía iatrógena en cirugía del tumor renal.

A description of our experience with iatrogenic spleen lesions requiring splenectomy caused during surgery for a renal tumour. Out of a total 83 nephrectomies due to renal tumour performed in our Centre between 1988 and 1996, 46 were left and 4 of them (8.7%) involve splenectomy. Clinical, surgical, pathoanatomical and follow-up data of these 4 cases is analyzed. Anatomical relationship of the spleen with kidney and colon, as well as factors to consider during surgery to avoid splenic lesions are discussed.

[Adenocarcinoma in ileocystoplasty]. / Adenocarcinoma en ileocistoplastia.

Case report of an adenocarcinoma in ileocystoplasty in a 54-year old female that at the age of 24 had undergone right nephrectomy and partial cystectomy surgery followed by vesical extension with ileon due to urinary tuberculosis. Discussion on the rare incidence of this condition, its diagnostic features, the need for long-term follow-up and the relevance of a broad resection of the affected intestinal portion.

[Retroperitoneal paraganglioma. Differential diagnosis with hypernephroma]. / Paraganglioma retroperitoneal. Diagnóstico diferencial con hipernefroma.

Paraganglioma are tumours that show embryological origin from the neural crest, and which derive from the paraganglia. They can be found in any location throughout the aorta and/or in association to the sympathetic chain. They can be either functioning or non-functioning based on hormone production. The authors present here a non-functioning retroperitoneal paraganglioma as an incidental finding in a 72-year old female patient. Pre-operative diagnosis was cystic hypernephroma, for which radical nephrectomy was performed. The extra-renal origin of the tumour was found subsequently on examining the piece. A discussion is included on the diagnosis, treatment, prognosis as well as a review of the literature.
