Abstract
This report describes a 60-year-old man with concurrent gastric extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) and classical Hodgkin lymphoma (CHL). Atypical, medium-sized, lymphoid cells proliferated in the mucosa to muscular layer of the stomach showing a lymphoepithelial lesion; admixed with Hodgkin/Reed-Sternberg (HRS) cells and an inflammatory cell background. MALT lymphoma cells expressed CD20, CD79a, PAX5, and BOB.1, and HRS cells expressed CD30, CD15, Epstein-Barr virus-encoded RNA, and EBV-latent membrane protein 1. Only CHL invaded into the regional lymph nodes. Two possibilities of transformation of MALT lymphoma into CHL and de novo CHL within MALT lymphoma are discussed.Entities:
