[Metastatic renal carcinoma of the breast. Presentation of 2 cases diagnosed by fine-needle aspiration puncture]. / Carcinoma renal metastásico en mama. Presentación de dos casos diagnosticados por citología mediante punción aspiración con aguja fina (PAAF).

Two cases of breast metastases from renal carcinoma are described herein. One patient underwent nephrectomy two years earlier and the other patient presented with bilateral involvement. The cytological features gleaned from fine needle aspiration biopsy are described. The diagnostic value of fine needle aspiration is underscored. This procedure makes surgery unnecessary and, furthermore, permits instituting a more adequate therapy.

[Inverted papilloma of the ureter. Unusual presentation and review of the literature]. / Papiloma invertido de uréter. Presentación excepcional y revisión de la literatura.

A case of inverted papilloma localized in the left pelvic ureter is described. The patient was submitted to a URS procedure with excisional biopsy of the tumor and fulguration of its base using the electric ureteral resectoscope. We believe that currently available endourologic techniques are the procedure of choice in the diagnosis of upper GU tract filling defects. An endourologic procedure permits conservative treatment when indicated and direct vision of the tumor site and urothelial mucosa.
