摘要
Coexistence of cutaneous T-cell lymphoma (CTCL) and a B-cell malignancy is rare. We report a case of mycosis fungoides (MF) associated with intestinal mucosa-associated lymphoid tissue (MALT) lymphoma, which is a low-grade B-cell lym phoma of marginal cell origin. To the best of our knowledge, there have been onl y two cases of coexistent CTCL and MALT lymphoma, and this is the first case wit h typical MF and intestinal MALT lymphoma. The coexistence in our case might be coincidental, but genetic predisposition and the immunoregulatory capacity of ne oplastic T lymphocytes may be factors contributing to this association.
