A 47-years-old Malay man presented with unremitting epigastric pain and loss weight for 3 months. At laparotomy, a large tumour mas was found in the liver and a few small nodules in the spleen. Histopathological examination revealed a hepatic angiosarcoma with metastsis to the spleen. He had exposure to formic acid fumes for more than 23 years in his work as a rubber tapper. The various chemical carcinogens that are implicated in this type of tumour are discussed. The possiblity of an association between formic acid fumes and development of angiosarcoma in the liver is highlighted.
