We present a patient with hepatocellular carcinoma causing obstructive jaundice due to intraductal growth, diagnosed intraoperatively by cholangiography and histological examination, and radically treated by left lobectomy, extrahepatic biliary tract resection and Roux-en-Y hepaticojejunostomy. Survival after operation was 13 months. Other similar cases reported in the literature are reviewed.

Acetylator phenotype was determined, using sulphamethazine, in 37 patients with histologically confirmed discoid lupus erythematosus, who were free from visceral damage, and in 157 normal control subjects. Twenty patients (54%) and 90 control subjects (57.4%) were slow acetylators (p not significant). Acetylator polymorphism appears not to be related to the risk of developing pure cutaneous discoid lupus erythematosus.
