Synchronous renal malignancies are seldom encountered or diagnosed post-renal resection. A combination of renal cell carcinoma (RCC) and urothelial carcinoma (UC) is most commonly reported.Typically, the RCC subtype is clear-cell RCC; however, a combination of collecting duct carcinoma (CDC) and UC has rarely been reported in the existing literature. Here, we present two cases of synchronous renal malignancy, specifically a combination of CDC and UC, in the ipsilateral kidney.

PURPOSE: Malignant peripheral nerve sheath tumors most often arise from the anatomically discernible peripheral nerve or neurofibroma. METHODS: A 55-year-old man had a rapidly growing pedunculated large mass on the sacrolumbar junction for 2 years. He has congenital neurofibromatosis type I. He had multiple caf-au-lait spots and multiple neurofibromas on the entire body. The mass developed from a subcutaneous nodule on the sacrolumbar junction and grew rapidly. The preoperative punch biopsy revealed a malignant peripheral nerve tumor. The mass was completely excised with 1 cm free margin above the deep fascial plane. RESULTS: There was no evidence of recurrence of tumor for 19 months of follow-up examination. CONCLUSION: Malignant peripheral nerve sheath tumor is very rare and has unique feature. We report a successful case of malignant peripheral nerve sheath tumor with the review of the literatures.

Fifty nine patients who had been admitted to Seoul National University Hospital from April to October in 1986 were prospectively examined by a pulsed Doppler echocardiography on one day before cardiac catheterization. The sample volume was placed both just proximal and distal to pulmonic valve on 2-D echocardiogram. 1) Among the three morphologic patterns of the flow velocity, triangular and intermediate types indicate pulmonary hypertension (sensitivity 84%, specificity 86%), and round type indicates normal pulmonary arterial pressure (sensitivity 86%, specificity 84%). 2) In the group with pulmonary hypertension acceleration time and ejection time were measured shorter (P<0.01), and prejection period was measured longer than the group without pulmonary hypertension (P<0.05). 3) The best correlation was obtained between PEP/AT and mean pulmonary arterial pressure (r=0.77). Acceleration time alone also correlated well with mean arterial pulmonary pressure(r=-0.69). 4) In STI measurement and its correlation with pulmonary arterial pressure, no significant difference was observed when recorded in main pulmonary artery or right ventricular outflow tract. But in the latter position, late, systolic fluttering and variation in curve morphology occured less likely. 5) Our results indicate that the pulsed Doppler echocardiography is useful not only in the diagnosis of pulmonary hypertension but also in the quantitative estimation of pulmonary arterial pressure in different heart diseases. Futhermore this method may be a good tool for follow-up evaluation after surgical or medical treatment of patients with pulmonary hypertension.
