Introduction: Hodgkin lymphomas are B-cell lymphoid neoplasms histologically characterized by a mixed inflammatory cellular component and few Hodgkin/Reed-Sternberg neoplastic cells. Classical Hodgkin Lymphoma (CHL) represents 10% of all lymphoma cases and 85% of all Hodgkin Lymphomas. According to the current World Health Organization classification, CHL is divided into 4 types: Nodular Sclerosing (NS), Mixed Cellularity (MC), Lymphocyte-Rich (LR), and Lymphocyte-Depleted (LD). Objetive: We reviewed all cases of Classical Hodgkin Lymphoma in the Pathological Anatomy Department at Edgardo Rebagliati Martins National Hospital during 2015 to 2019, in order to determine the most frequent type, the incidence according to age and gender, phenotypical characteristics and relation to Epstein Barr Virus (EBV). Materials and Methods:  We performed a retrospective descriptive case s...

Hepatic epithelioid hemangioendothelioma (HEH) is a very rare malignant vascular tumor of endothelial origin, of slow progression and low malignity degree. It is more common in women, of unknown etiology. Clinical manifestations of HEH are non-specific, from asymptomatic to abdominal pain. The more frequent radiological features are nodular hepatic lesions, of variable size, which show appearance of "target sign" in computed tomography (CT) and magnetic resonance imaging (MRI), with capsular retraction. Hepatic metastases are the principal differential diagnosis. The clinical course is variable, with a mortality rate to the diagnosis of up to 50 % of the patients. The therapeutical options include the surgical extirpation (removal) of the tumor and hepatic transplant as the more useful, besides the regional /systemic chemotherapy and immunological treatment. The present case describes th...
