Utilizing medical thoracoscopy for the diagnosis of B-cell lymphoma presenting with pleural effusion: A case series.

A third of patients with non-Hodgkin's lymphoma (NHL) develop pleural effusion during the disease course for various reasons. In most cases, lymphoma-related pleural effusion is a manifestation of widespread systemic disease, signifying a high tumour burden and therefore, a poorer prognosis. On the other hand, primary pleural lymphomas (PPLs) exhibit exclusive or dominant involvement of serous cavities, without detectable solid tumour masses. PPL is an uncommon disease and is of two types: primary effusion lymphoma (PEL) and diffuse large B-cell lymphoma associated with chronic inflammation (DLBCL-CI). PPLs not related to PELs and DLBCL-CIs are exceedingly rare. Herein, we describe four patients with biopsy proven B-cell NHL. One had no extra-pleural involvement at the time of diagnosis, indicating PPL. In all cases, histopathological examination of pleural biopsies obtained via medical thoracoscopy (MT) were crucial in clinching the final diagnosis. Clinicians are alerted to the potential relationship between exudative effusion and NHL as well as the role of MT in the diagnosis of B-cell NHL.

Asymptomatic presentation of diffuse large B-cell lymphoma as isolated submental lymphadenopathy

Non-Hodgkin lymphoma (NHL) is the most common type of lymphoma, Diffuse larger B-cell lymphoma (DLBCL) being most common type of NHL. Patients usually present at later stage with b-symptoms, lymphadenopathy and organomegaly. Isolated asymptomatic lymphadenopathy is a rare presentation. A 50-year-old female presented with complaints of swelling in the sub mental region. It increased in size over 1month without any associated local or systemic symptoms. On examination a firm, non-tender, mobile swelling of around 2×1.5 cm was present at sub mental region. Abdominal examination revealed no organomegaly. Blood picture- HB- 9.7 gm/dl, TLC- 5200/mm3, neutrophils/ lymphocytes/ eosinophil/ basophils-43.4/44.4/5.1/0.4 and Platelets-2.41 lakhs/mm3. Ultrasonography study was suggestive of necrotic lymph node. Fine needle aspiration cytology demonstrated nonspecific reactive lymphadenitis. After routine pre-operative workup patient was taken up for lymph node excision in elective OR under general anesthesia and the excised lymph node was sent for biopsy. A histopathological diagnosis of diffuse large B-cell lymphoma was made and confirmed with Immunohistochemistry (IHC), (CD20-diffuse positive; CD3-focal positive; Cyclin D-negative; BCL6-positive; CD10- focally positive). Post-operative hospital stay was uneventful. Our case was atypical with asymptomatic presentation with isolated lymphadenopathy with suspicious lymphocytosis. Diagnosis was only possible by histopathology.

Primary splenic diffuse large B-cell lymphoma (PS-DLBCL) presenting in an asymptomatic patient after sports trauma

Primary splenic diffuse large cell lymphoma is unusual and accounts for 2% of all splenic lymphomas. The symptoms included left upper abdominal pain, indigestion, loss of appetite, generalized weakness, fever, anemia, and thrombocytopenia or elevated C Reactive Protein. The current case report, to our knowledge the first of its kind, presents unusual clinicopathologic findings, where the patient remained asymptomatic until the time of diagnosis but showed extensive splenic involvement with stage IV disease. Alternatively, the morphologic findings in this case were like to those seen in other Primary Splenic Diffuse Large B Cell Lymphoma reported in the literature. In conclusion, the present report emphasizes the need for additional case studies and research on the biology of this unusual subset of lymphoma.

Uncommon presentation of diffuse large B-cell lymphoma: oral and pulmonary involvements in a young patient: a case report

BackgroundDiffuse large B-cell lymphoma is the most common subtype of non-Hodgkin lymphomas that remains a major diagnostic challenge due to the variety of its clinical presentations. This case highlights the importance of early biopsy of oral lesions without tendency to heal to attain the diagnosis more quickly. To the best of our knowledge, this study is the first to focus on both oral and pulmonary involvements in a patient with diffuse large B-cell lymphoma.Case presentationThe presented case describes an Iranian 18-year-old girl with chronic cough and dyspnea referred for evaluation of the upper jaw due to bone exposure, bone loss, and soft tissue ulceration. Her medical history revealed mediastinal mass, cavitary lesion, and mediastinal lymphadenopathy. However, cytologic and immunohistochemical analysis did not show any evidence of malignancy. In this case a lymphoproliferative disease was suspected but ultimately the oral biopsy diagnosed diffuse large B-cell lymphoma and chemotherapy could be started.ConclusionsSystemic conditions should be considered as a possible cause of oral lesions and a biopsy should also be performed immediately if there is any doubt concerning the nature of the lesion. Moreover, some conditions necessitate multiple biopsies to attain an accurate diagnosis.

Tumor versus bland thrombus: diffuse large B-cell lymphoma presenting as cavernous sinus and left superior ophthalmic vein thrombosis.

A 66-year-old female with a history of sinusitis presented with persistent diplopia and worsening eyelid swelling. Examination revealed bilateral vision loss, cranial nerve palsies, left-sided chemosis, proptosis, and edema. Initial imaging showed sphenoid sinus opacification, bilateral ethmoid disease, lack of filling of bilateral cavernous sinuses, and partial thrombosis of the left superior ophthalmic vein. The sinus findings were evaluated with endoscopic sinus surgery, which was unremarkable. Subsequent orbital imaging suggested the lesions were in keeping with tumor thrombus as opposed to bland thrombus. CT scans revealed a large mass in the right axilla, which was biopsied and confirmed the diagnosis of diffuse large B-cell lymphoma (DLBCL). The patient was treated with anticoagulation, steroids, and chemotherapy resulting in marked improvement. Our report highlights a rare case of tumor thrombus from DLBCL causing bilateral cavernous sinus thrombosis and, to the best of our knowledge, the first documented case of superior ophthalmic vein thrombosis from tumor thrombus.

Diffuse large B-cell lymphoma with heart involvement: the relevance of the multidisciplinary and multiparameter approach

Lymphoma patients are at high risk of cardiovascular events due to anthracycline cardiotoxicity and, in rare cases, related to heart infiltration. The presence of cardiac masses adds further complexity to the management of lymphoma patients beyond myocardial chemotherapy-related toxicity, given possible unpredictable acute complications such as arrhythmias, atrioventricular block, myocardial ischemia, pericardial effusion and cardiac tamponade. Here we describe the clinical presentation and successful multidisciplinary management of diffuse large B-cell lymphoma with multifocal cardiac involvement identified by total body 18FDG positron emission tomography performed at disease staging.

Lacrimal sac diffuse large B-cell lymphoma presenting as sudden-onset binocular diplopia

Introduction: Diffuse large B-cell lymphoma (DLBCL) is a prevalent subtype of non-Hodgkin lymphoma (NHL) affecting predominantly elderly individuals. Case description: A 68-year-old man with a history of hypertension, hyperlipidaemia and a small pituitary gland tumour presented with sudden-onset binocular diplopia and right-eye blurry vision. A magnetic resonance imaging (MRI) of the brain revealed enhancing soft tissue in the right superolateral orbit inseparable from the lacrimal gland, extending medially to the right superior rectus muscle and soft tissue. Further scanning showed widespread metastasis to the bilateral retroperitoneal lymph nodes, adrenal gland, spine and lymph nodes in the neck. A biopsy of the lacrimal gland confirmed DLBCL. Conclusion: Primary lacrimal gland DLBCL is a rare and delayed diagnosis that often stems from the resemblance of its clinical manifestations to more benign conditions such as dacryocystitis, dacryostenosis or mucocele. Timely recognition and accurate diagnosis are essential for initiating appropriate treatment and improving patient outcomes.

Primary Extranodal Diffuse Large B-cell Lymphoma Presenting in the Lips: A Case Report and Literature Review.

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.
