Cokeromyces recurvatus in a Papanicolaou test: An exceedingly rare finding that can be mistaken for Paracoccidioides brasiliensis

Cokeromyces recurvatus is a zygomycetes yeast form that is very rarely detected in Papanicolaou (Pap) tests, in which it typically represents an innocuous colonizer. Its morphology closely resembles that of the better known Paracoccidioides brasiliensis , which can disseminate widely and cause clinically significant disease. We present a case of C. recurvatus detected in a cervical liquid-based preparation obtained from a 38-year old healthy woman. Careful cytomorphologic evaluation, in combination with culture and molecular techniques, was utilized to make a diagnosis and prevent the misdiagnosis of P. brasiliensis .
