Primary pulmonary plasmacytoma: A case report

PPP is a rare lung tumor, and diagnosis of this lesion on the basis of bronchoscopic biopsy is even rarer. With this case report, we seek to enhance the awareness and understanding of PPP. We recommend that in cases wherein chest imaging findings suggest multiple lung lesions, the possibility of pulmonary plasmacytoma should also be considered, and biopsy should be actively performed to confirm the diagnosis and guide treatment. This report provides valuable insights and guidance for clinicians in the management and diagnosis of patients with PPP.
