Hepatocellular carcinoma: incidental finding in cirrhotic explanted livers.
INTRODUCTION: Cirrhosis predisposes to the development of hepatocellular carcinoma (HCC), demanding that these patients undergo follow-up with imaging methods for the early detection of neoplastic nodules. Morphologic study of the explanted livers allows identification of lesions not detected pre-operatively. OBJECTIVE: To assess the frequency and to characterize the HCC found incidentally at pathological evaluation of explanted cirrhotic livers. MATERIAL AND METHODS: Thirty patients had HCC diagnosed in explanted cirrhotic livers. The livers were sectioned at intervals of 0.5 cm. Each detached nodule was selected for microscopic study according to size, color and/or consistency. Retrospective analysis of the clinical records was performed comparing available data from various imaging methods. RESULTS: In 11 patients, 16 HCC had previously been identified in the explants by one or more imaging methods. In the other 19 explanted livers (63.3%), HCC was incidentally found. All HCC identified in 9 patients and some of them in 10 patients were incidentally found, varying from microscopic focuses to 2 cm diameter lesions. They varied from only one (5 cases) to multiple nodules (7 cases). DISCUSSION: Imaging methods may underestimate the number of HCC in cirrhotic livers. Histological study is an essential tool that can early detect tumor nodules not previously detected by imaging methods. In our study, although small, multicentric HCC were identified, illustrating the multifocal nature of the hepatic carcinogenesis. Future studies must correlate these findings with patient outcomes. CONCLUSION: Characterization of explanted cirrhotic livers for HCC is important for previously known and incidentally found lesions.

[Gastrointestinal vascular malformation].
Dieulafoy's disease, described in 1898, has been considered a rarity. Morphologically is represented by single, large and tortuous artery located in the gastric submucosa and overlying by submucosal defect that is responsible for severe digestive bleeding. We report two cases of this gastrointestinal vascular malformation: one in the stomach and the other in the jejunum. We believe that better knowledge of this lesion and more reports about it are important to decrease the mortality rate in those cases.
