This study reports the first confirmed case of endobronchial diffuse large B-cell lymphoma, a rare form of Non-Hodgkin's lymphoma (NHL). Diagnosis was confirmed via histopathology and immunoglobulin heavy chain gene rearrangement detected by PCR.

Area of Science:

Oncology
Pulmonology
Hematology

Background:

Non-Hodgkin's lymphoma (NHL) is a diverse group of cancers affecting the lymphatic system.
Thoracic involvement, particularly in the mediastinum and lung parenchyma, is common in NHL.
Bronchial-associated lymphoid tissue (BALT) lymphoma typically presents as an endobronchial lesion, but diffuse large B-cell lymphoma infiltration is exceptionally rare.

Observation:

This case presents an extremely rare instance of endobronchial infiltration by diffuse large B-cell lymphoma.
The lesion was located within the bronchial structures, mimicking other endobronchial conditions.

Findings:

Histopathological examination confirmed the diagnosis of diffuse large B-cell lymphoma.
Polymerase chain reaction (PCR) analysis detected a specific immunoglobulin heavy chain (IgH) gene rearrangement, providing molecular confirmation.

Implications:

This report highlights the importance of considering rare NHL presentations in endobronchial lesions.
Accurate diagnosis through histopathology and molecular techniques like PCR is crucial for appropriate patient management.
Further research may elucidate the specific mechanisms and clinical behavior of this rare NHL subtype.
