    Abstract Echinococcus granulosus (sensu lato), a cestode that is endemic in Egypt, causes cystic echinococcosis (CE), a significant but neglected zoonotic disease that is prevalent throughout the world. Infected hydatid cysts are classified as fertile or non-fertile based on the presence of protoscoleces; nevertheless, the mechanism of non-fertile CE cysts remains unknown. The study aimed to assess whether granzyme B (GrB) expression and CD4 + /CD8 + could be related to the induction of non-fertile CE cysts. A total of fifty-eight individuals diagnosed with visceral hydatid cysts were selected, and they were further divided according to cyst fertility into fertile and non-fertile. Immunohistochemistry for CD4, CD8, and GrB was done. According to the results, hydatid cysts are common in adults and have no gender preference. The same clinical and laboratory data were shared by patients with fertile and non-fertile cysts (p = 0.186). GrB expression was not impacted by the fibrous deposition inside the hydatid cyst wall (p = 0.85); however, GrB was significantly correlated with the inflammatory density (p = 0.005). GrB expression was also found to be significantly higher in non-fertile cysts (p = 0.04). GrB expression is positively correlated with CD4 and CD8 expression. In conclusion, the expression of GrB in hydatid cysts may exacerbate the inflammatory response and impede cyst fertility while not affecting the fibrous deposition in the cyst wall.

    Abstract We report a case of hepatic lymphoepithelioma-like carcinoma-hepatocellular carcinoma subtype (LEL-HCC) in a 41-year-old man with chronic hepatitis C virus (HCV) infection. The patient presented with abdominal pain and further assessment revealed a hypoechoic mass on ultrasonography. Serum alpha-fetoprotein (AFP) was 13·6 ng/dl. The patient was diagnosed as hepatocellular carcinoma based on the established triphasic computed tomography (TCT) diagnostic criteria and he underwent a surgical resection of the mass. Microscopic examination showed sheets and cords of malignant epithelial cells intermixed with heavy lymphoid infiltrate, with more than 100 tumor-infiltrating lymphocytes (TILs) per 10 high-power-field (HPF). Based on immunohistochemical studies, the malignant cells were positive for Hep Par 1 and glypican 3, focally positive for cytokeratin 7 (CK7), and negative for cytokeratin 20 (CK20). TILs were diffusely positive for cluster of differentiation 3 CD3 with an approximately equal CD4/CD8 ratio. The patient was recurrence free at 25 months after surgery, as evident by CT and serum alpha-fetoprotein level. LEL-HCC is a rare variant of HCC with a relatively better prognosis. Exploring the potential for immune modulator-based therapy in this subset of tumors is highly recommended.

    Abstract Background: Hepatocellular carcinoma (HCC) remains a major health problem despite the emergence of several preventive and therapeutic modalities. HCC has heterogeneous and wide morpho-molecular patterns, resulting in unique clinical and prognostic criteria. Therefore, we aimed to study the clinical and pathological criteria of HCC to update the morpho-molecular classifications and provide a guide to the diagnosis of this disease.
    Methods: Five hundred thirty pathologically analyzed HCC cases were included in this study. The clinical and survival data of these cases were collected.
    Results: Hepatitis C virus is still the dominant cause of HCC in Egypt. Post-direct-acting antiviral agent HCC showed an aggressive course compared to interferon-related HCC. Old age, male gender, elevated alpha-fetoprotein level, tumor size, and background liver were important prognostic parameters. Special HCC variants have characteristic clinical, laboratory, radiological, prognostic, and survival data. Tumor-infiltrating lymphocytes rather than neutrophil-rich HCC have an excellent prognosis.
    Conclusions: HCC is a heterogenous tumor with diverse clinical, pathological, and prognostic parameters. Incorporating the clinicopathological profile per specific subtype is essential in the treatment decision of patients with HCC.
    Trial registration: This was a retrospective study that included 530 HCC cases eligible for analysis. The cases were obtained from the archives of the Pathology Department, during the period between January 2010 and December 2019. Clinical and survival data were collected from the patients' medical records after approval by the institutional review board (IRB No. 246/2021) of Liver National Institute, Menoufia University. The research followed the guidelines outlined in the Declaration of Helsinki and registered on ClinicalTrials.gov (NCT05047146).

    Abstract Castleman's disease (CD) is a primary lymphoproliferative disorder of the lymph nodes with rare extra-nodal primary affection.
    Presentation of case: Here we present a case of primary hepatic CD associated with hepatocellular carcinoma (HCC).
    Discussion: Sixty-two years old, male received direct-acting antiviral agents (DAAs) for HCV infection. Follow up revealed sustained virologic response; however, three hepatic focal lesions were accidently discovered. Triphasic CT confirmed the HCC nature of two masses while the other mass remained undiagnosed. Surgical intervention was the treatment of choice, and pathological examination showed a fairly circumscribed mass formed of angiolymphoid hyperplasia displayed atrophic germinal center, expanded mantle zone, and variable hyalinization. The radiological evaluation of lymph nodes was unremarkable. The patient is 40 months alive after resection, with no further management advised.
    Conclusion: The immune-modulatory effect of DAAs may induce hepatic CD development in a cirrhotic patient, necessitating further studies. A new radiologic finding was observed in the present case in the form of vessels traversing through the lesion with no attenuation or occlusion. Pathology remains the gold standard in the diagnosis of CD.
