First Report of a Late Lethal Pulmonary Biliary Embolism following Hepatic Microwave Ablation.

Microwave ablation (MWA) is an established tool in modern therapy of hepatic malignomas. Although it is generally a safe procedure, severe complications related to MWA have been reported in the literature. We report on the first case of a fatal pulmonary biliary embolism following hepatic MWA. The development of pulmonary biliary embolisms is possible and should be considered particularly in the case of by extensive ablation near liver veins.

[Benign multicystic peritoneal mesothelioma (BMPM) - a surprising differential diagnosis in case of an expected intraabdominal abscess formation]. / Das benigne multizystische peritoneale Mesotheliom (BMPM) ­ Eine überraschende Differenzialdiagnose bei Verdacht auf einen intraabdominellen Abszess.

The benign multicystic peritoneal mesothelioma is a rare disease. Most frequently, young women in reproductive age are affected by this disease. Nevertheless, there are known cases of multicystic peritoneal mesothelioma in male patients. The pathogenesis remains uncertain. Whereas asbestos fibers can cause the development of malignant mesothelioma, the exposure to asbestos particles cannot induce this type of mesothelioma. An inflammatory genesis is discussed as well as the idea of a neoplastic development. Since a high rate of recurrence after surgery is observed, an aggressive surgical treatment is recommended. The complete resection of affected tissue is recently considered to be the therapy of choice. The combination of complete surgical tumor reduction with an intraperitoneal hyperthermic chemotherapy (HIPEC) seems to be promising. Although malignant transformation is detected very rarely a close follow up in centers with high surgical and oncological expertise is recommended.
