A significant number of cases of chronic eosinophilic pneumonia remain
idiopathic in spite of a comprehensive search of associated causes, T
his study reports a patient with a classical clinical presentation of
chronic eosinophilic pneumonia and peripheral blood eosinophilia in wh
om selective sensitization to Candida albicans was demonstrated. This
yeast was present in the bronchoalveolar lavage culture and specific s
erum immunoglobulin (Ig)E and IgG against C. albicans were found in th
e patient's serum. Levels of these specific immunoglobulins diminished
with corticosteroid treatment and increased coinciding with a new out
break of symptoms after lowering the dosage of corticosteroids. To the
author's knowledge, this is the first case described of chronic eosin
ophilic pneumonia associated with sensitization to C. albicans. Evalua
tion of allergy to C. albicans should be performed in chronic eosinoph
ilic pneumonia before labelling cases as idiopathic.
