Five cases of fungaemia due to Fusarium spp. in cancer patients are de
scribed. Two were breakthrough cases, despite ongoing therapy with amp
hotericin B. Three were caused by Fusarium solani, one by F. oxysporum
and one by F. dimerum. Four patients died, three of them despite ther
apy with amphotericin B for between 5-37 days. We describe only the se
cond reported case of F. dimerum fungaemia. Since 1972, 93 cases of sy
stemic infection with Fusarium spp. have been described: 43 had positi
ve blood cultures and the overall mortality was 72%.
