Phagocytosis of Candida parapsilosis by polymorphonuclear leukocytes.

The authors present a brief case report on an unusual entity. This rare phenomenon observed in a peripheral smear is worth noting. Neutrophils and rare eosinophils show intracellular fungal cells; the size, shape, and budding are consistent with Candida parapsilosis.
