Malignant transformation of hepatocellular adenoma: how frequently does it happen?
Hepatocellular adenoma is a very rare disease in Japan, and institutions encounter only a limited number of cases. This is one of the reasons for the current skepticism in Japan over whether hepatocellular adenoma can truly undergo malignant transformation to hepatocellular carcinoma. However, hepatocellular adenoma is highly prevalent in Western countries, particularly in Europe, and textbooks...
متن کاملHepatocellular adenoma with malignant transformation in male patients with non-cirrhotic livers
INTRODUCTION Hepatocellular adenomas (HCAs), with a risk of malignant transformation into hepatocellular carcinoma (HCC), classically develop in young women who are taking oral contraceptives. It is now clear that HCAs may also occur in men. However, it is rarely reported that HCAs with malignant transformation occur in male patients with non-cirrhotic livers. This study aimed to characterize t...
متن کاملMalignant transformation of liver adenoma: an analysis of the literature.
As adenoma in other locations, hepatic adenoma (HA) may transform into hepatocellular carcinoma (HCC) and hepatocyte dysplasia is most probably the intermediate step between both conditions. Malignant HA may appear as microscopic or macroscopic areas of HCC within the HA. These areas are typically well differentiated and without vascular extension or satellite nodules. AFP measurements are not ...
متن کاملMalignant transformation of breast ductal adenoma: a diagnostic pitfall.
We present what is believed to be the first report of heterogeneous carcinoma arising from breast ductal adenoma. A 57-year-old woman presented with a nodule in her right breast. Histological examination of a vacuum-assisted biopsy specimen revealed epithelial tubular proliferation and papillary apocrine epithelium. The myoepithelial cells lining the tubules were confirmed by immunohistochemist...

Four patients are described in whom a follicular carcinoma developed following thyroidectomy for a benign follicular neoplasm. It is possible that the initial thyroid neoplasm was a well- differentiated follicular carcinoma which was microscopically indistinguishable from a benign adenoma. Realizing this pathologic pitfall in thyroid diagnosis, the need for meticulous examination of the pa...
