Peritumoral histopathologic findings in patients with chronic viral hepatitis-associated hepatocellular carcinoma. APMIS 2022; 130:346-356.

Abstract
Data on peritumoral histopathologic findings in patients with hepatocellular carcinoma (HCC) is limited. In this retrospective study, we evaluated the peritumoral histopathologic changes in patients with chronic viral hepatitis (CVH)-associated HCC (CVH-HCC) and their prognostic value. 61 consecutive cirrhotic patients who underwent liver transplantation due to CVH-HCC were included. Histopathologic features within 1 cm distance of the tumor, and their association with clinicopathological characteristics and prognosis were evaluated. A random representative slide of cirrhotic parenchyma unrelated to invasive and/or dysplastic foci was also evaluated for the same histopathologic criteria. The majority (85%, n = 52) were male with a median age of 55 ± 6.38 (range, 39-67). The etiologic agent was only HBV in 90% (n = 55). The most common peritumoral findings were portal inflammation (100%; n = 61), ductular reaction (100%; n = 61) and sinusoidal dilatation (95%; n = 58). Macrovascular invasion was observed only in four cases (7%) with mild peritumoral portal inflammation. Neutrophilic infiltration of the peritumoral portal tracts (n = 18; 30%) was significantly associated with pT4 tumor stage, tumor grade, macrovascular invasion, and pretransplant therapy. Patients with moderate or severe peritumoral sinusoidal dilatation tended to have worse prognosis, albeit not significantly. Peritumoral ballooning degeneration was associated with multifocality, recurrence and recurrence-free survival in both uni- and multivariate analysis. Peritumoral histopathologic changes in CVH-HCC can be classified as: changes related to pathogenesis, changes indirectly affecting prognosis, and changes directly affecting prognosis. Peritumoral prominent ballooning degeneration may be a predictor of recurrence while portal neutrophilic infiltration and sinusoidal dilatation seem to indicate poor prognosis.

Abstract
Hepatocellular adenoma (HCA) is a heterogeneous entity, from both the histomorphological and molecular aspects, and the resultant subclassification has brought a strong translational impact for both pathologists and clinicians. In this review, we provide an overview of the recent updates on HCA from the pathologists’ perspective and discuss several practical issues and pitfalls that may be useful for diagnostic practice.

Abstract
OBJECTIVES Our aim was to investigate the frequency of steatohepatitic morphology in hepatocellular adenoma (HCA) and correlate with its clinical parameters and risk factors underlying nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH). METHODS We examined a series of 41 liver resection specimens diagnosed with HCA for steatohepatitic changes. Background nonneoplastic liver was also evaluated. Clinical records were reviewed for risk factors of NAFLD/NASH. RESULTS Six steatohepatitic HCAs (SH-HCAs) were identified, with an overall prevalence of six (14.6%) of 41, of which three were HNF1α inactivated and three were inflammatory, but none were β-catenin mutated. Five of the six patients with SH-HCA had at least one known risk factor for NAFLD/NASH, including obesity (n = 4; 66.7%), diabetes (n = 5; 83.3%), hypertension (n = 3; 50%), and dyslipidemia (n = 1; 16.7%). Compared with the patients without SH-HCA, the patients with SH-HCA had a higher frequency of type 2 diabetes, obesity, and hypertension. Of the six SH-HCAs, background nonneoplastic liver showed significant steatosis in three (50%) cases and steatohepatitic changes in one (16.7%) case. CONCLUSIONS Approximately 15% of HCAs in our series demonstrated steatohepatitic changes. Lack of such morphology in β-catenin-mutated subtype suggests reassurance in this morphologic variant of HCA.

Two cases of benign hepatic nodules caused by sinusoidal dilatation with different hemodynamics. Clin J Gastroenterol 2020; 13:873-881. [PMID: 32418022 DOI: 10.1007/s12328-020-01129-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2019] [Accepted: 04/24/2020] [Indexed: 10/24/2022]
Abstract
We describe two cases of benign nodules caused by sinusoidal dilatation with different hemodynamic statuses. Case 1 was a 50-year-old woman with a 1-cm nodule that showed a low density in the arterial phase of computed tomography. Pathologically, there were no atypical cells with sinusoidal dilatation, and immunostaining was negative for CD34. We speculated that sinusoidal dilatation was caused by congestion due to loss of frequency of the central vein. In contrast, case 2 was a 50-year-old woman with a 1.5-cm nodule that was highly stained in the arterial phase of computed tomography. Although she had a sinusoidal dilatation similar to that in case 1, immunostaining was positive for CD34. Sinusoidal dilatation was thought to be caused by hyperperfusion of arterial blood. Moreover, CD34 may be potentially useful for the differentiation of the hemodynamic status.

Abstract
INTRODUCTION Hepatic adenomas (HAs) are a benign and relatively rare type of liver neoplasms. We review the diagnosis, evaluation, and potential therapeutic management options for patients with HA. METHODS A comprehensive review of the English literature was performed utilizing MEDLINE/PubMed and Web of Science databases with end of search date the 30th April of 2018. In PubMed, the terms "hepatocellular," "hepatic," "liver," and "adenoma," "adenomatosis" were searched in the title and/or abstract. RESULTS Recent advances in molecular classification of HA have determined distinct subtypes with specific clinical, pathological, and imaging characteristics. In general, cessation of exogenous hormonal administration or weight loss may lead to HA regression. Surgical resection, either open or laparoscopic, should be considered in patients with symptoms and risk factors for hemorrhage or malignant transformation. These risk factors include tumor diameter greater than 5 cm, β-catenin activated subtype, and/or male gender. The management of acute hemorrhage should primarily aim at achieving hemodynamic stability via angioembolization followed by elective resection, whereas malignant transformation is treated according to oncologic resection principles. Although pregnancy is one of the known risk factors for tumor growth and associated complications, the presence of an HA per se should not be considered a contradiction to pregnancy. CONCLUSION Future genomic-based multicenter studies are required to provide a strong basis for formulating an evidence-based risk-adapted model that guides individualized management strategies for patients with HA.

Abstract
The distinction of hepatocellular adenoma from well-differentiated hepatocellular carcinoma (HCC) can be difficult in some cases, especially on biopsy specimens. These borderline cases often occur in men or older patients and may have β-catenin activation or focal atypical morphologic features (such as small cell change, prominent pseudoacinar formation, cytologic atypia, focally thick plates, and/or focal reticulin loss) that are insufficient for an unequivocal diagnosis of HCC. The term "atypical hepatocellular neoplasm" has been advocated for these tumors, but a number of other terms, including "atypical adenoma," "hepatocellular neoplasm of uncertain malignant potential," and "well-differentiated hepatocellular neoplasm with atypical or borderline features" have also been proposed. This review proposes guidelines for designating tumors as atypical hepatocellular neoplasm and describes clinical, morphologic, immunohistochemical, molecular, and cytogenetic features that distinguish these tumors from typical hepatocellular adenoma and HCC.
