I read the recent report by Pujani et al. with a great interest. They concluded that "Ki-67 was found to be useful in differentiating between follicular adenoma and follicular carcinoma, but since the sample size of our study was small, larger studies are needed to confirm this observation as well as to assign a cutoff value for differentiating benign from malignant tumors." [1] As Pujani et al. noted, there are some limitations due to methodology of this report. Not only the few subjects but also no age and sex matched case control design are big problems that limit the clinical usefulness of this work. Indeed, there are also other left questions. The problems on the immunostaining of Ki-67 should also be discussed. False positive and false negative due to Ki- 67 tests are already reported in the study in colorectal cancer. [2]
