BRIEF REPORT

Concurrent Lung Squamous Cell Carcinoma and Extranodal Marginal Zone B-Cell Lymphoma of Mucosa-associated Lymphoid Tissue Type Muhammad Adrish, MD,* Sindhaghatta Venkatram, MD, FCCP,w Masooma Niazi, MD,z and Gilda Diaz-Fuentes, MD, FCCPw

Summary: The coexistence of primary lung cancer and

lymphoma is a rare finding. We present a case of a 66year-old woman with marginal B-cell lymphoma of mucosa-associated lymphoid tissue type with lung, mediastinal lymph node, and bone marrow involvement. Surveillance imaging after treatment for lymphoma revealed persistent uptake by positron emission tomography scan. A transbronchial biopsy revealed the marginal B-cell lymphoma and a well-differentiated invasive squamous cell carcinoma. Management was changed to address new pathologic findings. Key Words: marginal B-cell lymphoma, squamous cell carcinoma of lungs, bronchoscopy, multiple malignancies

but can also arise from the lung, salivary glands, and thyroid gland.2 Pulmonary extranodal MZL is a rare entity, which accounts for
