[Gastric metastasis from renal cell carcinoma. Pathogenical hypothesis and literature revision]. / Metástasis gástrica de un adenocarcinoma renal. Hipótesis patogénica y revisión de la literatura.

Secondary gastric tumours are very uncommon clinical entities and even more so when the site for the primary tumour is the kidney. Only 11 cases of life diagnosis have been described up to now. Contribution of one case report: a female patient presenting with upper GI tract haemorrhage secondary to gastric metastasis from renal cell carcinoma four years after radical nephrectomy. A literature review is made on the cases described up to date in living patients and a pathogenic hypothesis established based on the theoretical dissemination routes for the cases of gastric location of the metastasis.

Metástasis gástrica de un adenocarcinoma renal. Hipótesis patogénica y revisión de la literatura / Gastric metastasis from renal cell carcinoma. Pathogenical hypothesis and literature revision

Los tumores gástricos secundarios constituyen una entidad clínica poco habitual, más aún si la localización del tumor primitivo es el riñón. Hasta la actualidad tan solo se han descrito 11 casos diagnosticados en vida. Se presenta un caso clínico de una mujer que presentó una hemorragia digestiva alta secundaria a la presencia de una metástasis gástrica de carcinoma de células renales cuatro años después de la nefrectomía radical. Se realiza una revisión bibliográfica de los casos descritos hasta la fecha en pacientes vivos y se establece una hipótesis patogénica de acuerdo a las teóricas rutas de diseminación para los casos de localización metastática gástrica

[Intrascrotal lymphangioma: report of 2 cases and review of the literature]. / Linfangioma intraescrotal: aportación de dos casos y revisión de la literatura.

Congenital lymphatic disease with scrotal location is particularly uncommon in adults and, in general, requires an exhausting differential diagnosis of testicular and paratesticular masses; among them, the lymphangioma is exceptional. Diagnosis is based on signs and symptoms, evolution and radiological studies such as ultrasound and computerised tomography as well as characteristic findings in the anatomopathologic study such as cystic dilation with endothelial walls and lymph content with no signs of malignancy. Treatment is usually surgical. Two cases of intrascrotal lymphangioma, one at Buck's fascia level in the corpus cavernosum and the other one at the subdermal tissue in the scrotal wall are contributed. An analysis is made of the usefulness of the different imaging diagnostic methods, and complete surgical resection of the lesion is proposed as the choice therapy.

[Prognostic factors in prostatic carcinoma treated with radical radiotherapy: stages A, B, and C]. / Factores pronósticos en el carcinoma de próstata tratado con radioterapia radical: estadios A, B y C.

Analysis of a series of 118 patients with histological diagnosis of prostate carcinoma, localized stages A2, B and C, treated with external radiotherapy with radical purpose between July 1964 and December 1991. The 5-year cause-specific survival was 69% years and 62% at 10 years. Disease-free survival was 56% and 48% at 5 and 10 years respectively. Local, locoregional and distant relapse-free survivals were 91%, 75% and 65% at 10 years respectively. Several factors characterize each tumour, influencing the therapy failure. In our series, non-differentiated, stage C tumours with pathological LDH levels at diagnosis and treated with AP-PA fields showed decreased survival and greater relapse ratios. Two separate factors influence on distant failure: LDH pathological levels at diagnosis and non-differentiated tumours. External radiotherapy is a therapeutical alternative in localized stages of prostate carcinoma, which offers little morbidity and good tolerance, similar results to those obtained with surgical treatment.

[Pneumoperitoneum: infrequent complication of lithiasic pyonephrosis]. / Neumoperitoneo: complicación infrecuente de la pionefrosis litiásica.

A case of lithiasic pyonephrosis evolving with intrapyelic gas formation, with positive urinary culture for Escherichia coli, is presented. Original clinical presentation was a picture of acute peritonitis with pneumoperitoneum. Clinical and radiological findings were indicative of exploratory laparotomy. The picture was resolved surgically, the procedure adopted being nephrectomy with retroperitoneal space drainage and empirically chosen antibiotics. The paper establishes the uncommon nature of this complication, and includes a literature review.

[Renal hydatid cyst: a nuclear magnetic resonance study]. / Quiste hidatídico renal: estudio con resonancia magnética nuclear.

A case of renal hydatid cyst (R.H.C.) in which study both traditional diagnostic methods (such as serology, radiology, ecoraphia, C.A.T., etc.) and the newer ones, including Nuclear Magnetic Resonance (N.M.R.) were used, is presented. The diagnostic characteristics of this type of cystic pathology were reviewed through N.M.R. study, as well as current criteria to outline a correct differential diagnosis with simple Renal Cysts (R.C.). Finally, a theoretical place for each of these methods within the diagnostic algorithm of renal masses is suggested.
