Clonal relationship in multisited mucosa‐associated lymphoid tissue lymphomas: a single‐centre experience

However, in mucosa‐associated lymphoid tissue (MALT) lymphomas it remains largely unexplored. Patients diagnosed at our institution with multisited MALT lymphoma, from January 2009 to October 2018, were studied.
