Clinical case report and literature review: metachronous colorectal splenic metastases.

A 52-year-old woman with a rising carcinoembryonic antigen CEA, no clinical or radiological findings, a negative colonoscopy, and a positron emission tomography (PET) scan that revealed an isolated hypermetabolic lesion in the spleen. The patient underwent splenectomy by laparoscopic surgery. The pathological study confirmed the presence of an isolated metastasis to the spleen. This case reveals the rare occurrence of isolated splenic metastases in the context of colorectal cancer and illustrates the role of PET when a patient shows a rising CEA with negative clinicoradiological studies.

[Primary epidermoid carcinoma of the renal pelvis]. / Carcinoma epidermoide primitivo de pelvis renal.

Epidermoid carcinomas account for 9 to 17% of primitive pyelocaliceal tumours. Key predisposing factor are infections and lithiasis, pre-operative diagnosis being difficult due to insidious growth and absence of pathognomonic syndrome. The paper introduces one case of epidermoid pyelocaliceal carcinoma where diagnosis was supported by intravenous urography, ultrasound and CAT, and where the catheter-obtained cytology was definite in terms of diagnostic value. Ureteropyeloscopy can be a crucial examination in case of diagnostic doubt. Choice therapy is nephroureterectomy with vesical collar resection when the tumour's anatomical state or the subtotal nephrectomy allow it. Prognosis of these tumours is very poor, mean survival of patients being of about 4 months. Our patient died one month after surgery.

[Epididymal adenomatoid tumor. Review of the national literature and report of a case]. / Tumor adenomatoide de epidídimo. Revisión de la literatura nacional y aportación de un caso.

Benign epididymal epithelial tumours are very uncommon. Their frequency rating is as follows: adenomatoid tumour, leiomyoma and papilliferous cystoadenoma. This paper contributes a new case of epididymal adenomatoid tumour in a 29-year old male who presented with testicular pain. Diagnosis was achieved through physical examination and echography. A simple tumourectomy was performed. As a result of this case, a review was made of the Spanish literature.
