Mycosis fungoides associated with Mediterranean lymphoma

Mycosis fungoides was observed in a 71-year-old male with Mediterranean lymphoma, a B-cell malignancy. It is proposed that this association is not incidental since hypergammaglobulinaemia and even monoclonal gammopathies have repeatedly been described in cutaneous T-cell lymphomas. Mediterranean lymphoma might have resulted from (a) helper cell activities of tumor T-lymphocytes, (b) common antigenic stimuli, or (c) deranged T-B cooperation due to concomitant mycosis fungoides.
