Abstract
Hepatoid carcinoma (HC) encompasses epithelial extrahepatic tumors exhibiting features of hepatocellular carcinoma (HCC) both by morphology and immunohistochemistry. Distinguishing metastatic HCC from HC may be challenging, particularly when limited material, such as a cytologic specimen, is available. HC from prostatic origin is unusual and has only rarely been characterized by cytology. Herein we present an 86-year-old male with history of castration-resistant prostate cancer developing a left adrenal gland nodule. Fine needle aspiration revealed a poorly differentiated malignant neoplasm diagnosed as metastatic hepatoid prostatic adenocarcinoma based on immunohistochemistry (positive for HepPar1, AFP, NKX3.1, PSMA, and Racemase; and negative for CK7, CK20, cytokeratin 34betaE12, p63, and Arg-1). Because prostatic carcinoma with hepatoid features is rare, and the patient had failed standard therapy, next generation sequencing was performed in an attempt to identify druggable molecular targets. Well-known prostate carcinoma-related alterations were found in three genes (CDK12, AR, and SPOP). In addition, three variants of uncertain significance (DDR2 R128C, SRC P428L, and HNRNPU K574Sfs*32) were identified, which to the best of our knowledge have not been previously reported. Our results support the power of an immunohistochemistry panel including Arg-1 and HepPar1 when HC is suspected, and highlight the value of cytology for comprehensive diagnostic evaluation.

Large-Scale Tissue Microarray Evaluation Corroborates High Specificity of High-Level Arginase-1 Immunostaining for Hepatocellular Carcinoma. Diagnostics (Basel) 2021; 11:diagnostics11122351.

Abstract
Arginase-1 catalyzes the conversion of arginine to ornithine and urea. Because of its predominant expression in hepatocytes, it serves as a marker for hepatocellular carcinoma, although other tumor entities can also express arginase-1. To comprehensively determine arginase-1 expression in normal and neoplastic tissues, tissue microarrays containing 14,912 samples from 117 different tumor types and 608 samples of 76 different normal tissue types were analyzed by immunohistochemistry. In normal tissues, arginase-1 was expressed in the liver, the granular layer of the epidermis, and in granulocytes. Among tumors, a nuclear and cytoplasmic arginase-1 immunostaining was predominantly observed in hepatocellular carcinoma, where 96% of 49 cancers were at least moderately positive. Although 22 additional tumor categories showed occasional arginase immunostaining, strong staining was exceedingly rare in these entities. Staining of a few tumor cells was observed in squamous cell carcinomas of various sites. Staining typically involved maturing cells with the beginning of keratinization in these tumors and was significantly associated with a low grade in 635 squamous cell carcinomas of various sites (p = 0.003). Teratoma, urothelial carcinoma and pleomorphic adenomas sometimes also showed arginase expression in areas with squamous differentiation. In summary, arginase-1 immunohistochemistry is highly sensitive and specific for hepatocellular carcinoma if weak and focal staining is disregarded.

Abstract
Hepatocellular carcinoma (HCC) is one of the commonest carcinomas and leading causes of cancer-related death. Although, in patients with cirrhosis, radiologic diagnosis has improved significantly over the years, needle biopsy and histopathological assessment remains an important diagnostic modality. Most importantly, histopathological diagnosis is essential in patients with contending extrahepatic primaries, those with no known HCC risk factors, patients with ambiguous radiological features, and many other clinical contexts. Helpful features such as high serum alpha-fetoprotein (AFP) serologies are known to be present in many other tumor (including but not only HCC) and nontumor contexts and therefore not only lack sufficient diagnostic specificity for HCC but also create the potential to overlook non-HCC AFP-producing tumors, of which there are many. Therefore, using clinical examples and other examples from the medical literature, this review discusses several clinical and histological mimics of HCC and proffers an approach for practicing pathologists geared toward avoiding missteps.

Abstract
Hepatocellular carcinoma (HCC) is a morphologically heterogeneous tumor with variable architectural growth patterns and several distinct histologic subtypes. Large-scale attempts have been made over the past decade to identify targetable genomic alterations in HCC; however, its translation into clinical personalized care remains a challenge to precision oncology. The role of pathology is no longer limited to confirmation of diagnosis when radiologic features are atypical. Pathology is now in a position to predict the underlying molecular alteration, prognosis, and behavior of HCC. This review outlines various aspects of histopathologic diagnosis and role of pathology in cutting-edge diagnostics of HCC.

Abstract
CONTEXT.— Immunohistochemistry (IHC) has become increasingly important in the evaluation of pathologic conditions in the genitourinary (GU) organs. In addition to careful evaluation of hematoxylin-eosin sections and generation of a differential diagnosis, choosing the optimal panel of IHC markers becomes even more important when the biopsy material is very limited. The following summary of our experience supplemented with relevant literature review exemplifies how to use IHC to facilitate pathologic diagnosis in the GU system. OBJECTIVE.— To describe our experience with the most common immunohistochemical markers used in GU pathology. DATA SOURCES.— Institutional experience and literature search comprise our data sources. CONCLUSIONS.— Application of IHC provides enormous benefits to the interpretation of GU pathologic conditions, including benign and malignant lesions. However, both insufficient and excessive types of use of IHC, as well as incorrect interpretations in common and rare GU conditions, could present pitfalls in diagnosis.

Abstract
Malignant ascites in prostatic acinar adenocarcinoma is very rare. We present an 84-year-old man with a rare malignant ascites due to prostatic adenocarcinoma demonstrating hepatoid differentiation by immunohistochemistry. The patient was diagnosed with the malignant ascites due to metastatic prostatic adenocarcinoma. We identified the unique cytological feature of envelopment of tumour cell clusters by benign mesothelial monolayers.

Abstract
We present a case with space-occupying lesion in cirrhotic liver, diagnosed as hepatocellular carcinoma on immunohistochemistry, who underwent F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) and showed FDG-avid lesions in liver as well as in the prostate. These findings guided in establishing the diagnosis of prostate cancer, metastasizing to liver by performing additional immunohistochemical markers. PET/CT was also useful in identifying coexisting non-Hodgkin's lymphoma.
