We experienced a rare case of a lymphomatous polyp of mantle cell type forming a polypoid mass lesion in the duodenum bulbous together with advanced gastric cancer. A total gastrectomy was performed, and the specimen revealed atypical small- to medium-sized lymphoid cells with indented nuclei, which infiltrated the Peyer's patch and formed a nodular mass in the lamina propria and submucosa of the duodenum. The lymphoma cells also infiltrated the lymphoid follicle of the gastric mucosa, spleen, and regional lymph node with a typical mantle zone pattern. Flow cytometric analysis of the single cells of the lymph node and immunohistochemistry of a paraffin-embedded specimen revealed that the lymphoma cells expressed surface CD5, CD19, CD20, and nuclear cyclin D1. Chromosomal analysis of this single cell suspension revealed that these lymphoma cells have trisomy 3 in conjunction with t(11;14)(q13;q32), which is frequently seen in mucosa-associated lymphoid tissue lymphomas (MALToma) in the stomach and is also reported in mantle cell lymphoma as a secondary genetic alteration. Our report suggests that trisomy 3 may be a common chromosomal abnormality in lymphomatous polyps of mantle cell type.
