Squamous cell carcinoma is an extremely rare primary liver tumour. A 42-year-old man presented at our hospital on 19 February 1986, with pain in the right upper quadrant of the abdomen and general fatigue, and reported an 8 year history of this complaint. Ultrasonography showed four cystic masses in the liver with a maximum diameter of 15 cm, one of which contained a solid component. A computed tomography (CT) scan confirmed a huge, predominantly cystic, mass in the liver with a small solid component and irregular wall. Calcifications were seen in the solid components. On 22 April 1986, a laparotomy was performed but the masses were too large to be removed. During 15 years of follow-up after the laparotomy, there had been no change seen in his abdominal CT scan. He subsequently arrived at our hospital again on 10 July 2001 with loss of appetite and of body weight. A CT scan showed a cyst in the liver of 25 cm in diameter with calcification that had a large solid part invading the liver. A post-mortem pathological dissection showed multiple cysts, the largest of which was 25 cm in diameter. They had large solid parts with calcification invading the liver. There were widespread metastatic lesions. Microscopic examination showed the tumour to be a well differentiated squamous cell carcinoma. To the best of our knowledge, this is the first report of a squamous cell carcinoma arising from 15 multiple non-parasitic hepatic cysts after a 15 year follow-up. Furthermore, 23 years had passed since the patient's symptoms appeared for the first time.
