Mycosis fungoides with monoclonal gammopathy, hypereosinophilia, and hyper-IgE.

A 61-year-old female with a well-established Mycosis fungoides also had a marked hypereosinophilia, a monoclonal gammopathy IgGk type, and an elevated IgE level. Such unusual association of abnormalities of the immune system in a given Mycosis fungoides patient has not been described before in the absence of any other underlying cause.
