A rare case of peritoneal coccidioidomycosis.

Coccidioidomycosis, also known as valley fever, is a fungal infection that can develop after inhalation of arthroconidia from soil. Coccidioidomycosis infections are most common in the southwestern United States and typically involve the lungs. Risk factors for extrapulmonary spread, which can be life-threatening, include older age, diabetes, HIV and AIDS, late-term pregnancy, immunosuppressant drug use and African or Filipino ancestry. This article describes incidental identification of coccidioidomycosis of the peritoneum, an extremely rare site for dissemination, during bariatric surgery in a patient without known risk factors.
