Hyalohyphomycosis caused by Paecilomyces variotii in an obstetrical patient

Abstract

A case of hyalohyphomycosis, caused by Paecilomyces variotii, has been described in a 31-year-old female, who had undergone a cesarean section in her 39th week of pregnancy for a trial of labour. Five days following delivery, she complained of sharp, cramp-like pains, localized to the incisional site. She became febrile (38.2 degrees C). An ultrasound examination revealed a complex mass and fluid within the pelvis and upper abdomen. The fluid was drained by a needle aspiration and the patient was administered a regimen of antibacterial drugs. Microscopic examination did not reveal any bacteria in a gram stained preparation and cultures were negative as well. However, the fluid demonstrated a few segments of septate, hyaline hyphae, with cultures yielding a pure growth of P. variotii. An exoantigen procedure, currently under development, was helpful in confirming the identity of the patient's fungus. The patient's condition improved following needle aspiration and her recovery was uneventful. It is reiterated that certain infections, attributed to low-grade opportunistic pathogens, such as P. variotii, may be cured by proper surgical drainage.
