Rare Case Report of Pulmonary Mucosa-Associated Lymphoid Tissue Lymphoma.

Bronchial mucosa-associated lymphoid tissue is the site of the uncommon malignancy known as mucosa-associated lymphoid tissue (MALT) lymphoma. Due to its lack of distinct clinical signs and imaging characteristics, it is frequently misdiagnosed and underdiagnosed. After receiving unsuccessful treatment for a lung infection or tuberculosis in multiple tertiary care hospitals, we report a male patient who had a solid lesion in his left upper lung for 18 years. The patient was ultimately diagnosed with pulmonary MALT lymphoma at our hospital through a CT-guided percutaneous lung biopsy using the Jiang technique (i.e., employing a laser-assisted guidance system in addition to the conventional CT guidance). It is vital to extend one's perspective, synthesise extrapulmonary signs, and work toward the conditions essential to get a high-quality biopsy specimen when an intrapulmonary lesion is hard to explain by general lung illnesses.
