Peritoneal mesothelioma presenting with 'kissing' liver metastases

Abstract

A 61-year-old woman was diagnosed with an incidental liver lesion with a satellite lesion that had features of a secondary liver metastasis. Investigations for primary sites did not reveal a primary tumour. The lesion was not amenable to biopsy due to location. Intraoperatively, the two lesions were adjacent, but the first was on the diaphragm and the lesion was in segment 7 of the liver. The liver lesion underwent non-anatomical resection and the diaphragmatic lesion was resected separately. The histopathology diagnosed peritoneal mesothelioma in the lesion removed from diaphragm and the liver lesion to be local metastatic spread to an area of liver that was in close contact (a 'kissing' lesion). This report portrays a rare occurrence of liver metastases from peritoneal mesothelioma and discusses the current evidence for diagnosis and treatment.
