METHODS: Thirteen cases of cystic renal carcinoma confirmed by operation and pathology were examined by ultrasonography, and the cystic walls, septa and solid mural nodules were studied. RESULTS: Solid mural nodules of some cases and irregular thickening of the cystic walls and septa were characteristic findings for the ultrasonic diagnosis of cystic renal carcinomas. According to their pathologic mechanisms and sonographic features, cystic renal carcinomas were classified into 3 patterns: unilocular cystic mass, multiloculated cystic mass and cystic-solid mass. CONCLUSIONS: Typical cystic renal carcinomas can be well diagnosed, while atypical cases may be misdiagnosed as benign renal cysts by ultrasonography. Color Doppler ultrasonography and needle aspiration guided by ultrasonography are helpful in the diagnosis of these atypical cases.展开更多

They account for 46 percent of the hospitalized patients with carcinoma of penis in the same time (1966--1990). Among them, 54 cases were diagnosed originally as squamous cell carcinoma.Surgical treatment included total amputation of the penis, urethral transplantation (23 cases), excision of testis (15 cases) and resection of the regional lymph nodes (25 cases). Our study demonstrates that the malignant degree of verrucous carcinoma of penis is low and it should be differentiated from squamous cell carcinoma in diagnosis and treatment. It is preferable that local tumour resection or partial amputation of penis should be carried out.展开更多
