[Malignant peritoneal mesothelioma].

Mesothelioma is a neoplasm originating from the mesothelial surface lining cells of the serous human cavities. It may involve the pleura, less frequently the peritoneum rarely, the pericardium, the tunica vaginalis testis and ovarian epithelium. Asbestos has been widely used in industry. A causal relationship between asbestos exposure and pleural, peritoneal and pericardial malign mesothelioma was suggested, the risk of cancer being correlated to cumulate exposure. Studies from National Cancer Institute, USA, show that the malignant mesothelioma is a rare and aggressive asbestos related malignancy. The symptomatology is insidious and poses difficult problems in diagnosis and treatment. This paper presents the case of a 59 year old patient with malignant peritoneal mesothelioma who worked almost 40 years as an electrician, exposed to asbestos fibers. He was hospitalized for important weight loss, abdominal pain and tiredness being diagnosed after imaging tests with a giant tumor, localized at the abdominal upper level, which seems to originate from the spleen's superior pole. During surgery we discovered a tumor with cystic parts, intense vascularized, which turn to be adherent in the upper side to the lower face of the left midriff cupola, to the spleen superior pole and 1/3 middle level of the great gastric curve. It was performed surgical ablation of the tumor, splenectomy with favorable postoperative evolution, the patient being now under chemotherapy treatment.
