MALT Lymphoma Diagnosed on Transbronchial Lung Biopsy: A Case Report

Mucosa associated lymphoid tissue lymphoma (MALToma) of the lung is a rare, low-grade B-cell lymphoma arising from the bronchus associated lymphoid tissue (BALT), usually requiring surgical biopsy using thoracoscopy for diagnosis. We present a case of MALToma of the lung diagnosed with a transbronchial lung biopsy (TBLB) specimen. A 63 year old man presented with hemoptysis. Chest X ray disclosed right upper lobe consolidation. Pathological examination of the TBLB specimen revealed lymphocytic infiltrations that stained positive with CD 20 and CD 79a on immunohistochemical studies. Thus, TBLB is a valuable and relatively non invasive method for diagnosing primary pulmonary MALT lymphoma. *Corresponding author: Dr. Sandeep Gupta, Department of Pulmonary Medicine and Critical Care, Amar Hospital, Patiala, India, Tel: 91-9888391241; E-mail: [email protected] Received January 17, 2012; Accepted March 12, 2012; Published March 14, 2012 Citation: Gupta S, Goel K, Kaur J (2012) MALT Lymphoma Diagnosed on Transbronchial Lung Biopsy: A Case Report.
