Saccharomyces cerevisiae emboli in an immunocompromised patient with relapsed acute myeloid leukaemia

Summary In humans, Saccharomyces cerevisiae (baker's yeast) is found infrequently as a commensal of mucosal surfaces and rarely causes infections. We describe a case of cutaneous septic emboli developing in a patient with relapsing acute myeloid leukaemia M6 who had recently been treated with clofarabine. Yeast forms were seen on skin biopsy and S. cerevisiae was isolated from her Hickman line. We are not aware of any previous case reports of cutaneous emboli associated with this organism.
