Head Neck Pathol

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.

After describing the anatomy of the spleen and the most important immunohistochemical stains for identifying cellular constituents of the normal splenic compartments, etiologies of splenomegaly and the diagnostic approach for spleen biopsies are discussed using the example of a North African patient with a recent migration background and sudden fever. The focus is on infectious diseases and the morphology and molecular features of hematolymphoid neoplasms, particularly the primary "splenic B‑cell lymphomas" according to the World Health Organization (WHO) classification. The importance of clinicopathological correlations and interdisciplinary cooperation in splenic pathology is emphasized.

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.
