Objective To investigate the clinical features and CT appearances of primary adenosquamous carcinoma (ASC)of the liver and to improve the understanding of this disease for the sake of misdiagnosis.Methods The clinical features and CT appearances in 7 patients proved by operation and pathology were reviewed,retrospectively.Results All of the patients had dull pain in upper abdo-men,fever,chills and a long history of cholangitis and biliary calculi.In addition,all patients had not the history of hepatitis B and liver cirrhosis.And the serum AFP level was normal.The single lesion was found in every patient including 4 lesions in the left lobe of liver and the other 3 in the right lobe.Plain CT showed all masses with hypodensity,heterogeneity and unclear edge in liver,and multiple irregular and more hypodense areas in lesions were found.Slight heterogeneous honeycomb-like enhancement in the arterial phase was showed.In the venous phase,persistent honeycomb-like enhancement with uneven separations,nodular bulge and hypo-dense necrotic area was found.In the delayed phase,further honeycomb-like enhancement with hypodense necrotic area and obvious-ly enhanced nodular bulge was showed.The bile ducts in the liver and around the mass were dilated and had pneumatosis in company with lithiasis in choledochus and intrahepatic bile duct in 5 patients.Conclusion Primary hepatic ASC has certain clinical character-istics in older patients.The CT characteristic features included:honeycomb-like lesions with persistent,heterogeneous,delayed en-hancement and heterogeneous separation,uneven inner edge and enhanced nodular bulge.

Objective To investigate the clinical features and prognosis of the patients with renal cell carcinoma and venous tumor thrombus.Methods Fifty-six patients with renal cell carcinoma and venous tumor thrombus were selected as our subjects,who underwent radical nephrectomy and thrombectomy in the Second Hospital of Tianjin Medical University from June 2002 to May 2014.There were 28 patients with stage Ⅰ tumor thrombus,l5with stage Ⅱtumor thrombus,9 with stage Ⅲ tumor thrombus and 4 with stage Ⅳtumor thrombus.All patients underwent renal tumor resection and embolectomy,and were follow-up.Results Of all the patients,46 were male and 10 were female with a mean age of 61.7(age ranging from 42 to 83).Twenty-four were presented on the left kidney and 32 were right.The clinical features were as follows:The tumor size was 2.5 to 14 cm in diameter(mean:6.2 cm),there were 21 cases with low back pain,18 cases with hematuria,lcases with abdominal.Pathological results showed that 39 with clear cell carcinoma,9 with papillary cell carcinoma,3 with chromophobe cell carcinoma,1 with low-differentiated cell carcinoma and 1 with undifferentiated cell carcinoma,3 with sarcomatoid differentiation.Forty-three patients were followed up,and the median follow up period was 20.4 months (2-90 months).The median survival time for the patients was 47 months and the 5 year overall survival was 45.2%.The survival time of the patients with early tumor thrombus(below hepaticvein) was (55.3 ± 4.9) month,significantly longer than that of the patients with advanced tumor thrombus (above hepaticvein) ((24.8 ± 5.3) months,P =0.047).Conclusion Patients with renal cell carcinoma and venous tumor thrombus are characterized with high malignancy and poor prognosis.Surgical operations are effective therapies for the patients.Long term outcome of the early tumor thrombus patients is significantly better than that of the advanced tumor.
