No full textUnusual presentation of gouty tophus in the liver with subsequent appearance in the same site of HCC: A correlate diagnosis? Case report 11 Medical and Health Sciences 1112 Oncology and Carcinogenesis
No full textBackground: Although gout is a common disease, the presence of gouty tophi outside joints is rare and in literature, there is to date only one report of hepatic tophaceous nodule. We would like to highlight here the difficult diagnostic workup in a patient with history of cancer and the presence of a tophus inside the liver. Moreover, we address the possible etiologic role of chronic inflammation related to tophi and liver cancer. Case presentation: We present the case of a 72-year-old man with a localization of gouty tophus in the liver, who thereafter developed a hepatocellular carcinoma (HCC) in the same site. The patient was followed up after surgery for left renal cancer from 1992 to 2011, when a hepatic nodule was discovered for the first time. After a detailed evaluation, the nodule was classified as a urate tophus of the liver. However, further follow-up showed that the nodule increased in size and changed its characteristics, bringing to the diagnosis of HCC. Conclusions: With the present case report, we would discuss the possible neoplastic degeneration of a gouty tophus and its etiologic role favouring cellular degeneration linked to chronic inflammation. We would also highlight the importance of histopathological evaluation of hepatic lesions in gouty patients at high risk of liver neoplasm, due to the difficulty in characterizing gouty tophi by imaging
Incremental Diagnostic Value of F-18 FDG PET/CT Over MRI in a Pediatric Patient With Suspected Hepatoblastoma and Histologic Diagnosis of Focal Nodular Hyperplasia.
No full textStrategies in the study of hepatocellular carcinoma worldwide
No full textHepatocellular carcinoma (HCC) is a widespread disease
all over the world, its annual incidence being estimated
between 0.25 and 1 million new cases per year [ 11.
HCC is a sex-linked disease, with a significantly higher
frequency in males [2]. The figure observed in each geographical
region is different, and depends mainly on the
basis of collection of the data (hospital, population, autopsy
register, etc.). However, when dealing with large
numbers and/or with a rather frequent disease, such as
liver carcinoma, the bias related to the above-mentioned
factors may be minimized
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
