Department of Histopathology and Cytology, Apollo Cancer Center, Chennai, IND.
Background and objective Lymphomas can involve the gastrointestinal (GI) tract as a primary disease or as a secondary spread of systemic disease. The GI tract is a key site for extranodal lymphomas, with Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) occurring in this region. This study aimed to analyze the demography, anatomic distribution, histological subtypes, and immunomorphological characteristics of all lymphomas with a primary GI presentation at a quaternary care hospital in southern India.

Hepatic Epstein-Barr virus-positive inflammatory follicular dendritic cell sarcoma (EBV+ IFDCS) represents a rare form of liver malignancy. The absence of distinct clinical and radiological characteristics, compounded by its rare occurrence, contributes to a challenging diagnosis. Here, we report a case of a 54-year-old Chinese female with a background of chronic hepatitis B virus treated with entecavir and complicated by advanced fibrosis presenting with a liver mass found on her annual surveillance ultrasound.

Unlabelled: In recent years, the prevalence of thoracic aortic aneurysm has increased, and in most cases this pathological condition is diagnosed accidentally. The aim of the current study was to determine the relationship of clinical, laboratory and morphological data with the presence of aorta wall dissection in patients with thoracic aortic aneurysm to reveal factors associated with aorta dissection.
Materials And Methods: The following data of 109 patients mean aged of 53 years with thoracic aortic aneurysm (43 patients with aortic dissection) were analyzed: presence/absence of arterial hypertension, indicators of general blood analysis and blood biochemistry, immunomorphological characteristics of the expression of Von Willebrand factor.

Hepatoblastoma is an exceptionally rare malignancy in adults with just over 70 non-pediatric cases reported in literature. Recounted is a case of a 49-year-old female who presented with acute right upper quadrant abdominal pain, elevated serum alpha fetoprotein and a large liver mass on imaging. Hepatectomy was performed under clinical suspicion of hepatocellular carcinoma.

Clear cell papillary renal cell tumor (CCPRCT) is a distinct clinical entity with characteristic pathological features and non-aggressive clinical behavior. Diagnostically challenging cases present when there are immunomorphological findings of CCPRCT associated with heterogeneous morphologies, aggressive histological features, and advanced pathological stages-so-called CCPRCT-like tumors. In this report, we describe a heterogeneous, multifocal renal tumor with immunomorphological characteristics of CCPRCT but with associated aggressive features such as sarcomatoid and necrotic areas, perirenal and sinus fat involvement, and most notably, lymph node metastasis composed entirely of classic CCPRCT morphology and immunophenotype.
