“…DLBCL is the most common type of NHL in HIV-infected as well as non-HIV infected patients ( 3 ). The majority of patients with PPL suffer from marginal zone lymphomas of the mucosa-associated lymphoid tissue type ( 14 , 15 ). DLBCL directly arising from lung tissue is extremely rare, and accounts for 0.4% of all lymphomas ( 16 ).…”

Primary diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma; however, the involvement of the lung and central nervous system (CNS) in patients with DLBCL is rare. Furthermore, patients with DLBCL rarely exhibit specific clinical symptoms, which may delay definitive diagnosis. The present study reports the case of a 42-year-old man suffering from primary DLBCL with concurrent pulmonary and cerebral involvement. The patient suffered from human immunodeficiency virus infection and presented with symptoms including dry cough, thoracalgia, intermittent mild fever and mild headache. Thoracic computed tomography scans revealed multiple pulmonary masses, and brain magnetic resonance imaging scans revealed nodules in the left frontal cortex and bilateral basal ganglia. A percutaneous lung needle biopsy test confirmed the diagnosis of DLBCL. In addition, positron emission tomography revealed the involvement of other parts of the body in DLBCL. The aim of the present study was to present the clinical, radiological and histological characteristics of the patient, which may aid physicians in diagnosing pulmonary and CNS involvement in DLBCL.

Primary pulmonary lymphoproliferative neoplasms

et al. 2018

Pulmonary lymphoproliferative neoplasms are rare lung tumors and account for <1% of all lung tumors. Among them, primary pulmonary lymphomas (PPL) constitute the majority, which include Non-Hodgkin’s lymphoma (NHL) that comprise of mucosa-associated lymphoid tissue lymphoma, diffuse large B-cell lymphomas and other rare types of NHL and lymphomatoid granulomatosis. HL, which arises secondary to contiguous spread from the mediastinum, is the rarest type of PPL. Other entities described within the umbrella of pulmonary lymphoproliferative neoplasms include pleural lymphomas and posttransplant lymphoproliferative disorders (PTLD) – which occurs in the poststem cell and organ transplant patients. These neoplasms although rare, have a favorable prognosis, which does not depend on disease resectability. Moreover, with its nonspecific presentation, diagnosis is challenging, which often leads to delayed diagnosis or misdiagnosis in many cases. Therefore, knowledge of this entity is important for the practicing pulmonologist. This review article aims to describe the clinical presentation, diagnosis and management of primarily the entities within PPL, as well as pleural lymphomas and PTLD.
