Late onset chronic mucocutaneous candidiasis with lymphoma and specific serum inhibitory factor.

A patient with late onset chronic mucocutaneous candidiasis developed lymphocytic lymphoma. A specific inhibitor of in vitro lymphoproliferative responses to candidal antigen was detected in her serum which persisted following clinical remission of candidiasis after combined amphotericin-B and 5-Fluorocystosine therapy. It is unclear whether the combined therapy was exclusively anticandidal, nonspecific immunostimulant or cytotoxic affecting the underlying incipient lymphoma.
