Pulmonary parenchymal infiltrates in a patient with CD20-positive multiple myeloma.
A 53-yr-old woman developed a dry cough after the completion of multi-agent chemotherapy. The biopsy specimens showed diffuse infiltrates with multiple myeloma (MM) cells. Immunohistochemistry revealed positive staining in MM cells with surface CD20, surface CD38, and cytoplasmic IgG. This report represents the first reported case of pulmonary parenchymal infiltrates in a patient with CD20-positive MM.
