[Local relapse and single site of metastatic involvement of renal tumour. Prognostic factors and survival]. / Recidiva local y afectación metastásica única de tumor renal. Factores pronósticos y supervivencia.

OBJECTIVE: To evaluate the clinical and pathological characteristics and survival in patients surgically treated for renal tumours that had local recurrence or metastasis to a single site. MATERIAL AND METHODS: A retrospective study of 321 nephrectomies, evaluating the clinical and pathological variables in patients having local recurrence or metastasis to a single site, and who were treated surgically. Study and comparison of survival in the different groups. RESULTS: The only factor found to have an independent influence on local recurrence is pathological stage. Local recurrence and the presence of metastasis to a single site have similar survival rates, both being statistically worse than in patients without metastasis at diagnosis, but better than in those having metastasis at diagnosis. CONCLUSIONS: The presence of local recurrence has the same prognosis as a single excisable metastatic site, the prognosis being better than those initially with metastasis subjected to nephrectomy before receiving systemic treatment.

[Pheochromocytoma with thrombus in cava]. / Feocromocitoma con trombo en cava.

Pheochromocytoma, a paraganglioma of suprarenal location, is a catecholamine-secreting chromaffin cell tumour. Spread of these tumours to the vena cava is rare and the thrombus only reaches the right atrium in exceptional cases. We present the case of a patient who, without previous symptomatology, presented with a clinical picture of multiorganic dysfunction with primary manifestation of a suprarenal tumour with vascular spread to the right atrium affecting the right suprahepatic vein.
