[Plasmacytoid variant of urothelial carcinoma: a case report]. / Variante plasmocitoide del carcinoma urotelial: a propósito de un caso.

Plasmacytoid urothelial carcinoma is an extremely rare pathological finding. We report our experience of one case. A 60 year old male with hematuria of two years evolution, with frequency and dysuria. A tumor was found and he received surgical treatment by TURB at first. The pathology result was a plasmacytoid urothelial carcinoma. Subsequently a radical cystectomy with urinary diversion was performed. The patient received follow-up until his death.

[Study on the findings of an immediate renal gammagraphy and its effect on the survival of a kidney graft]. / Estudio de los hallazgos de la gammagrafía renal inmediata y su influencia en la supervivencia del injerto renal.

INTRODUCTION: We assessed the effect of the findings of the renal gammagraphy (99mTc-DTPA) taken in the first 24 hours after the transplant in the survival of the kidney transplant. MATERIALS AND METHOD: We retrospectively studied 413 kidney transplants carried out between January 1994 and December 2008, with emphasis on normal gammagraphic findings or alterations in the vascular, parenchymal and excretory stages, as well as their effect on the survival of the graft. RESULTS: Of the 413 transplants, 44 (10.7%) presented alterations in the vascular stage, 256 (62%) in the parenchymal stage and 269 (65.1%) in the excretory stage. The mean follow-up of the entire group was 72.5 months (± 54.1 DE). The univariate analysis shows that the survival of the graft is significantly less in patients with alterations in the vascular stage (OR: 3; IC 95% 1.9 - 4.9 p<0.001), in the excretory stage (OR: 2.5; IC 95% 1.5 - 4; p=<0.001) in the parenchymal stage (OR: 2.21; IC 95% 1.3-3.36; p=0.001). The multivariate studies of the gammagraphic variables that affect the survival of the graft show that the presence of alterations in the vascular stage (OR: 3; IC 95% 1.9-4.9; p<0.001) in the parenchymal stage (OR: 2; IC 95% 1.2-3.3; p=0.005) are directly related to survival. This data is also confirmed by means of the actuarial survival analysis of the graft at 3 and 5 years. CONCLUSIONS: The presence of alterations in the vascular stage and in the parenchymal stage of the renal gammagraphy immediately after the transplant are variables that affect the survival of the graft.
