Candidal abscess of the spleen in patients with acute leukemia.

Between January 1974 and July 1976, three adult patients with leukemia, therapy-associated granulocytopenia and febrile courses unresponsive to broad spectrum antibiotic therapy were operated upon for a preoperative diagnosis of candidal abscess of the spleen. The diagnosis was based upon a high index of suspicion of invasive candidiasis in this immunosuppressed group of patients; the failure of the patients to respond to the empiric administration of broad spectrum antibiotics, salicylates and steroids, and the presence of discrete scintiscan defects on liver-spleen scan with both 99Tc sulfur colloid and 67Ga citrate. Multiple splenic abscesses containing candidal organisms were confirmed in all three patients, and two of the three also had multiple small abscesses of the liver. The fourth patient, whose liver-spleen scintiscans were abnormal only in showing splenomegaly and whose febrile course responded to aspirin, did not have a candidal abscess of the spleen at the time of celiotomy which was undertaken for fever of unknown cause. The antemortem diagnosis and treatment of candidal splenic abscess in patients with leukemia is dependent upon a high index of suspicion and appropriate clinical correlation with diagnostic tests. Although the prophylactic oral administration of mycostatin to patients at high risk may prevent this once fatal complication, only prompt and aggressive treatment can cure it.
