Approximately 30-40% of malignant lymphomas are classified as diffuse large B-cell lymphoma (DLBCL), with 30% of DLBCL cases manifesting as extranodal lymphomas. Among these extranodal DLBCLs, primary DLBCL in oral lesions, particularly in the lips, is rare. While the treatment methods, chemotherapy assessment, and prognosis for nodal and extranodal DLBCLs are generally similar, diagnostic challenges can lead to delayed therapeutic intervention. We herein present a recent case of primary extranodal DLBCL in the lips that was swiftly diagnosed and managed using rituximab-containing chemotherapies. Our experience underscores the important role that hematologists play in identifying the possibility of oral hematological tumors, thereby allowing for a rapid diagnosis and timely intervention.

Background: Lymphatic metastasis commonly occurs in patients with papillary thyroid carcinoma and medullary thyroid carcinoma. The clinical and imaging characteristics of recurrent laryngeal nerve (RLN) invasion by extranodal extension (ENE) of metastatic lymph nodes remain understudied. This study aimed to evaluate these characteristics in patients with thyroid carcinoma.

Purpose: To evaluate current MRI-based criteria for malignancy in mesorectal nodal structures in rectal cancer.
Method: Mesorectal nodal structures identified on baseline MRI as lymph nodes were anatomically compared to their corresponding structures histopathologically, reported as lymph nodes, tumour deposits or extramural venous invasion. All anatomically matched nodal structures from patients with primary surgery and all malignant nodal structures from patients with neoadjuvant treatment were included.

Background: Classic Hodgkin lymphoma (CHL) is an extremely common non-acquired immunodeficiency syndrome (AIDS) defining malignancy and its incidence is rising. CHL is usually present in the lymph node and extranodal involvement is rare. Primary CHL of the gastrointestinal (GI) tract is exceedingly rare.

Primary central nervous system (CNS) lymphoma of the meninges is a rare tumor that originates in the meninges and does not show parenchymal or systemic spread. CNS involvement by natural killer (NK)/T-cell lymphoma accounts for only 2% of all extranodal NK/T-cell lymphomas, and primary NK/T-cell lymphoma of the meninges is even rarer. The present study reports a case of a 55-year-old male patient with primary NK/T-cell lymphoma.

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.
