Primary gastric Hodgkin's lymphoma is a rarely encountered lesion. Most cases are observed in the course of systemic disease. Other cases have been reclassified in retrospective studies as non-Hodgkin's lymphomas, after the employment of immunohistochemistry. Some Hodgkin's lymphomas may masquerade non-Hodgkin's lymphomas, and vice versa. Therefore, an accurate diagnosis is important, as treatment and outcome differ significantly for these entities. We report a case of primary Hodgkin's lymphoma arising in the stomach of a 46-year-old male, and discuss the diagnostic approach as well as the differentials of Hodgkin's disease in this anatomic site.

Head and Neck Classic Hodgkin, T and NK Lymphomas with Eosinophilia.
Head Neck Pathol

Joint Pathology Center, Silver Spring, MD, USA.
Eosinophilia is a notable feature in various hematological malignancies, including specific types of leukemias and lymphomas that may occur in the head and neck. In hematologic malignancies, eosinophilia can be primary, driven by genetic abnormalities, or secondary, resulting from cytokine and chemokine production by the neoplastic cells or the tumor microenvironment. This review examines the association between eosinophilia and head and neck hematolymphoid malignancies including Classic Hodgkin lymphoma, T-cell lymphoblastic leukemia, mature T and NK-cell lymphomas, and Langerhans cell histiocytosis.

Background: T/histiocyte-rich large B-cell lymphoma (T/HRBCL) is a highly aggressive subtype of diffuse large B-cell lymphoma characterized histologically by the presence of a few neoplastic large B cells amidst an abundant background of reactive T lymphocytes and/or histiocytes. T/HRBCL commonly affects the lymph nodes, followed by extranodal sites, such as the spleen, liver, and bone marrow, with rare occurrences in the gastrointestinal tract. Primary gastrointestinal T/HRBCL lacks specific clinical and endoscopic manifestations, and it is difficult to differentiate from inflammatory diseases, nodular lymphocyte predominant Hodgkin lymphoma, and other diseases on a histological basis, thereby hindering early diagnosis.

Activated PI3K delta syndrome (APDS) is a primary immunodeficiency that is caused by mutations in the PI3K signalling pathway resulting in either gain-of-function or loss-of-function phenotypes of APDS 1 and 2. Malignancy is one of the most serious complications associated with APDS patients, with the most commonly occurring of these being lymphoma, and is the most common cause of death in APDS patients. Management of APDS is complex and variable due to the heterogeneous nature of the disease and ranges from antimicrobial and immunosuppressant agents to haematopoetic stem cell transplantation.

Immunity suffers a function deficit during aging, and the incidence of cancer is increased in the elderly. However, most cancer models employ young mice, which are poorly representative of adult cancer patients. We have previously reported that Triple-Therapy (TT), involving antigen-presenting-cell activation by vinorelbine and generation of TCF1-stem-cell-like T cells (scTs) by cyclophosphamide significantly improved anti-PD-1 efficacy in anti-PD1-resistant models like Triple-Negative Breast Cancer (TNBC) and Non-Hodgkin's Lymphoma (NHL), due to T-cell-mediated tumor killing.
