Abstract: | Two cases with spontaneous regression of a histologically confirmed hepatocellular carcinoma (HCC) are presented. This rarely seen phenomenon of a spontaneous tumor involution is discussed and compared with the current literature. The clinical symptoms were very similar to that of a liver abscess. A 56-year-old male suffered from a multicentric, highly differentiated, trabecular HCC. First symptoms were epigastric pain, septic fever and arthritis. The tumor marker AFP was constantly normal and no hepatitis could be verified. A resection of the tumor was performed. In patient 2, a 74-year-old male, a multicentric, clear cell HCC was found. The patient had completely recovered from hepatitis type B and within the liver tissue no viruses could be identified. Clinical symptoms were mainly characterized by upper abdominal pain and septic fever. AFP was excessively elevated (3850 ng/ml) but returned to normal preoperatively. In both cases, the specimen showed a subtotal necrotic HCC with insignificant amounts of vital tumor cells. Neither patient had a liver cirrhosis macroscopically, however patient 2 had local periportal fibrosis histologically. After 24 and 41 months of follow-up, respectively, both patients are in good health |
