Benign Hepatic Neoplasms
Historically benign liver tumors were encountered incidentally during laparotomy or more re‐ cently during laparoscopy at which time definitive histological diagnosis can be established. However, with the utilization of advanced imaging modalities hepatic neoplasms have been in‐ creasingly identified, with a prevalence rate of up to 50% reported among the general popula‐ tion [1]. Among these i...
متن کاملBenign Hepatic Neoplasms
Hepatic lesions are frequently identified incidentally on • imaging performed for other purposes. With the exception of large lesions, benign hepatic neo• plasms are typically asymptomatic. With current high quality imaging, it is possible to differentiate • the majority of hepatic neoplasms as benign or malignant. Resection of indeterminant, worrisome lesions is generally • preferred over biop...
متن کاملRight trisegmentectomy for hepatic neoplasms.
Thirty patients had right trisegmentectomy for 19 primary hepatic malignant tumors, seven localized liver metastases and four benign lesions. A technical refinement that aided resection of bulky posterior and superior tumors was intrahepatic identification and control of the right hepatic vein. The operative mortality was 3.3 per cent. Late hepatic insufficiency was not observed. More than one-...
متن کاملOncogenes in hematopoietic and hepatic fish neoplasms.
Neoplastic transformation of cells has often been associated with changes in cellular oncogenes. While much information has been collected in mammalian systems, relatively little is known about the molecular basis of tumor progression in lower vertebrates. For our studies, tumors were collected from feral northern pike (Esox lucius) from Ostego Lake, MI, where the local population exhibited a 1...
متن کاملEstrogen production as a tumor marker in patients with gonadotropin-producing neoplasms.
Urinary estradiol production rates, plasma estradiol, and peripheral conversion of dehydroepiandrosterone sulfate (DHEAS) to estradiol were explored in patients whose neoplasms made human chorionic gonadotropin and/or human chorionic gonadotropin beta fragments. In five men with choriocarcinoma, estradiol production was elevated, plasma estradiol was high, and DHEAS conversion to estradiol rang...
