Non-functional Adrenocortical Carcinoma in the Wall of the Small Bowel.

BACKGROUND: Extra-adrenal non-functional adrenocortical carcinoma （ACC）is an extremely rare tumor with only eight cases having been reported at different localizations. CASE PRESENTATION: A 60-year-old woman was presented to our hospital with abdominal pain. Magnetic resonance imaging revealed a solitary mass abutting the wall of the small bowel. She underwent resection of the mass, and the results of histopathology and immunohistochemistry were consistent with ACC. CONCLUSION: We report the first occurrence of non-functional adrenocortical carcinoma in the wall of the small bowel in the literature. Magnetic resonance examination is sensitive enough to indicate the accurate location of the tumor and is of great help to clinical operation.

[Relationship between jugular vein thrombosis and extremity vein thrombosis by vascular color Doppler ultrasound].

OBJECTIVE: To explore the relationship between jugular vein thrombosis and extremity vein thrombosis in cancer patients by vascular color Doppler ultrasound. METHODS: A total of 79 cases with malignant tumors complicated with venous thrombosis undergoing vascular color Doppler ultrasound were analyzed retrospectively. All cases were divided into the group of jugular vein thrombosis (n = 36) and the group of extremity vein thrombosis (n = 43). The thrombotic factors of PT (prothrombin time), APTT (activated partial thromboplastin time), FIB (fibrinogen), HCT (hematocrit), PLT (platelet), PCT (plateletcrit), PDW (platelet distribution width), MPV (mean platelet volume), pathologic type and thrombotic time were compared between two groups. RESULTS: Between two groups, significant differences existed in APTT, pathologic types and before or after therapy (P < 0.05). However the other factors were not significant (P > 0.05). CONCLUSION: The clinicians should pay great attention to malignant tumor complicated with venous thromboembolism (VTE). An early diagnosis is essential to prevent pulmonary embolism (PE) and improve patient survival. Vascular color Doppler ultrasound may be used as the first-line examination. Preoperative and postoperative prophylactic anticoagulant therapy can reduce the risk of VTE in patients with high-risk factors.
