Pathomorphologic characteristics of small hepatocellular carcinoma: A special reference to small hepatocellular carcinoma with indistinct margins
Osamu Nakashima, Shigetaka Sugihara, Masayoshi Kage, Masamici Kojiro – 1 July 1995 – Some surgically resected small hepatocellular carcinoma (HCC) up to 2 cm in diameter have indistinct margins, and it is sometimes difficult to identify the margins of the cancer nodule in the resected specimen. We classified such tumors as small HCC with indistinct margins and carried out a morphological study to define their characteristics in comparison with small HCC with distinct margins as a control group. We have encountered 27 examples among 86 tumors smaller than 2.0 cm in diameter.
