INTRODUCTION: Peritoneal mesothelioma is a rare tumor, presenting difficulties in diagnosis and treatment. Peritoneum is the second most common area of the mesothelioma after pleura, and even synchronous pleural and peritoneal mesotheliomas are observed in 30–45% of all cases. The diagnosis may be difficult due to lack of specific symptoms and clinical findings. In addition, a delay in the diagnosis is not rare especially in the absence of previous asbestos exposure. Here we report a case of malignant peritoneal mesothelioma. The diagnostic and therapeutic approaches for these rare neoplasms are discussed.
CASE PRESENTATION: Prolonged abdominal pain and abdominal distension were the primary presentation symptoms and findings. A mass noted after imaging studies in the right lower quadrant of abdomen. Diagnostic laparoscopy and sampling done from the mesenteric node. Final diagnosis were possible with histological and immunohistochemical documentation of tumor characteristics, which were consistent with dictating a mesothelial origin. No history of asbestos exposure was reported. CONCLUSION: Peritoneal mesotheliomas are rare clinical entities. However, patients with prolonged abdominal pain and abdominal masses should be considered to have atypical pathologies such as peritoneal mesotheliomas.
