Incidentally Solitary, Synchronous, Metastatic Left Adrenal Mass From Colon Cancer
Mina Alvandipour,Mohammad Yasin Karami,Mehdi Khalvati,Hamed Khodabakhsh 대한대장항문학회 2016 Annals of Coloproctolgy Vol.32 No.2
The authors report the case of a 63-year-old man who underwent an open adrenalectomy for a synchronous, malignant, metastatic left adrenal tumor and a total colectomy for T3N0M1 (stage 4) primary, malignant colon cancer. Two polypoid lesions, one measuring 40 mm × 30 mm × 30 mm and the other measuring 20 mm × 10 mm × 10 mm, were found in the ascending colon and rectosigmoid (RS) junction, respectively, and a synchronous, malignant, left adrenal gland lesion measuring 70 mm × 50 mm × 30 mm was incidentally found on abdominal computed tomography scan. Histological examination revealed a metastatic, necrotic adenocarcinoma of the left adrenal mass, an adenocarcinoma of the cecal mass, and an adenomatous polyp (tubulovillous type) of the smallest polypoid lesion in RS junction that had invaded deeply into the submucosal layer. The patient recovered uneventfully, and his condition is now stable, with no evidence of local recurrence or metastatic disease, 2 years after the surgery. To the best of our knowledge, only 25 cases of an adrenalectomy for treating metastatic adrenal gland tumors have been reported to date; physicians should be aware of the possibility of this event.

Background: Liver failure is usually associated with the inflammation and oxidation of hepatocytes. Due to their unique properties, graphene and graphene-based nanostructures such as magnetic graphene oxide (MGO) are useful in biomedicine and engineering. In this study, synthesized MGO was used to improve the liver failure induced by carbon tetrachloride (CCl4). The hepatoprotective effects of intraperitoneal injection of MGO on the rat model of CCl4-induced acute liver failure were investigated. Materials and methods: In order to provide a rat model of acute liver failure, male rats were intraperitoneally injected with 2 ml/kg body weight CCl4. In the experimental groups, rats received 2 ml/kg CCl4 and 300 mg/kg MGO body weight simultaneously. Four days after injection, symptoms of acute liver failure appeared. The control, sham, CCl4, and CCl4 + MGO groups were compared and analyzed both histologically and biochemically. Results: The results indicated that the MGO injection reduced all CCl4-induced liver failure such as necrosis, fibrosis, inflammation, aspartate transaminase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) in the experimental groups of the rat model of acute liver failure. Conclusion: The hepatoprotective effects of MGO might be due to histopathological suppression and inflammation inhibition in the liver.
