# Primary Pulmonary Marginal Zone Lymphoma Presenting With Asymptomatic Lung Consolidation

## TL;DR

A rare case of lung lymphoma was diagnosed in a patient with an incidental lung mass found during a routine checkup.

## Contribution

This case highlights the diagnostic challenge of asymptomatic primary pulmonary marginal zone lymphoma.

## Key findings

- The patient presented with an incidental lung consolidation/mass.
- A tissue diagnosis was necessary to confirm primary pulmonary marginal zone lymphoma.

## Abstract

Pulmonary lymphoma is a rare condition involving the lung characterized by the abnormal proliferation of lymphoid tissue. Patients may either be asymptomatic or exhibit nonspecific clinical presentations and radiologic findings, making diagnosis challenging. Here, we describe a case of a female patient who presented to our clinic with an incidental radiological finding of pulmonary consolidation/mass. The final diagnosis of a primary pulmonary marginal zone lymphoma required a tissue diagnosis.
