[Bladder lymphoepithelioma-like carcinoma. Bibliographic review and case report].

Objective: Lymphoepithelial-carcinoma or lymphoepithelioma-like carcinoma is a rare tumour, the histology of which remembers nasal pharyngeal is lymphoepitheliomas. Their presence has been described in multiple localizations, but only 55 cases have been described in the bladder. We present a new case of bladder lymphoepithelial carcinoma and performed a review of all published cases, with the aim of defining its characteristics and try to obtain a therapeutic and prognostic guide applicable to this disease.

Venous malformation of the glans penis: efficacy of treatment with neodymium:yttruim-aluminum-garnet laser.

Objectives: Vascular anomalies in the urogenital tract are very rare and those located in glans penis are the most uncommon. There is some controversy concerning their nomenclature, diagnosis and treatment. We present an analysis of our experience and a critical review of the literature.

Renal angiomyolipoma: a study of 13 cases.

Arteriographic studies are valuable in the differentiation of angiomyolipoma from adenocarcinoma. Herein are described 13 cases of angiomyolipoma, in 10 of which angiographic studies were done. A correct preoperative diagnosis was made in 3 of the 10 cases and partial nephrectomy was done in 2.

[The diagnosis and partial nephrectomy of angiomyolipomas (author's transl)].

Renal angiomyolipoma is not a malignant tumor, and it is therefore to be treated only conservatively. The difficulty in distinguishing it from carcinoma nearly always leads to total nephrectomy. The study of the selective renal arteriogram enables preoperative diagnosis of angiomyolipoma even when not associated with tuberous sclerosis, and a partial nephrectomy.
