Primary carcinoma of the liver or hepatocellular carcinoma has a universal significance. It is closely as­sociated with cirrhosis. The entire liver is replaced by numerous small tumour nodules, often the size of an acinus, surrounded by a connective tissue network so that a histological examination is necessary to distinguish it from cirrhotic nodules.


In October 1981 a 40-year-old man presented with a history of jaundice and pain in upper right quadrant and epigastrium of three month’s duration. Initiallyhe had mild anorexia which increased gradually. He felt increasingly fatigued and had weight loss. On examination he had tenderness over the epigas­trium. The liver was enlarged and firm. The spleen was barely palpable. An upper gastrointestinal series failed to demonstrate any lesion. Blood chemistry showed SGPT 45 units, SGOT 120 units, alkaline phosphatase 30 K.A. units, total protein 6.2 gfdl, albumin 3.5 gJdl, globulin 2.7 g/dl and total bilirubin of 1.8 mg/dl. Hepatitis B surface antigen was positive. The patient underwent an exploratory laparatomy. The liver was covered with many small grey nodules, measuring from 0.3 to 0.5cm in diameter. One nodule was biopsied. The stomach, duodenum, small and large intes­tine and pancreas were of normal appearance. Lymph nodes in porta hepatie, mesenterie and para-aortie loca­tions were not enlarged. Postoperatively, the general condition of the patient did not improve. He developed inereasingjaundice with a total bilirubin of 17mg/dl Aseites appeared and increased rapidly. Biopsy diagnosis of the liver nodule rendered an initial diagnosis of a malignant neoplasm consistent with HCC. The patient had a quick downhill course with in­creasing jaundice, aseites and development of esophageal varices. The liver enlarged and became more tender. Bleeding tendencies ensued and he died within one month of the hospitalization from liver failure. The normal lobular structure of the liver was replaced by pseudonodules surrounded by fibrous tissue bands in which bile duet proliferation was seen. The pseudonodu les consisted of large, polygonal neoplast ie cells with prominent vesicular nuclei. The nucleocytoplas­mic ratio was increased. The cell boundaries were distinct and the cytoplasm was granular with a faint eosinophilic appearance. The nuclei were large and hyperchromatic. The nuclear membranes were irregularly thickened with clumped chromatin near the margin. Nucleoli were prominent (Figures 1 and 2).

Central necrosis with collections of neutrophilic leukocytes mimicking suppurative granulomas was present in some nodules. In some areasThe tumour cells were so anaplastic that classification as a hepatocellular ncoplasm was difficult or impossible (Figure 3).

The diagnosis of diffuse type of HCC was made.


The clinical presentation of HCC is quite variable and nonspecific2-7,9,11,12. The relationship of antecedent cirrhosis to primary carcinoma of the liver is an important finding1. Cirrhosis accompanies about 55% to 85% of liver cell carcinomas in various reported series5,6,10,12 whereas only 30% of bkle duet carcinomas are said to have arisen in cirrhotic livers10.  The classification of HCC into ‘nodulart, “massive” and ‘diffuse” types is based on the gross morphology of the neoplasm11 . The diffuse type of HCC infiltrates the whole liver by numerous very small tumour nodules, often the size of an aelnus, surrounded by a connective tissue network, so that microscopic examination is required to distinguish it from cirrhotic nodules8. The diffuse type of hepatocellular carcinoma has the tendency of widespread intrahepatic metastasis with ex­treme infiltration of the hepatic vein tributaries8,11. This explains the rapid enlargement of the liver and early development of hepatic decompensation8. Our patient with the diagnosis of HCC of diffusety pe had a quick enlargement of hard nodular liver filling the abdomen, with massive third compartment expansion, increasing jaundice, portal hypertension, elevated alkaline phosphatase level initially but increasingly other liver dysfunctions also ensued. Bleeding tendencies manifested and he had a downhill course with hepatic coma terminally and died within 1 month of the diagnosis.
