Coccidioidomycosis is a fungal infection endemic to the Southwestern United States that has a clinical presentation resembling community-acquired pneumonia. Disease occurs after inhalation of airborne arthroconidia. Dissemination to a variety of organ systems via hematogenous spread from a primary pulmonary focus may then occur. Coccidioidomycosis rarely involves the abdominal cavity. The authors review the spectrum of abdominal and pelvic presentations of coccidioidomycosis and report 6 unusual cases, including acute appendicitis, hepatitis and adnexal masses. Pathologists played a critical role in the diagnosis of these presentations by recognizing spherules in tissue. In only 2 of the cases were Coccidioides species cultured.
Article: Intra-abdominal fungal infections[Show abstract] [Hide abstract]
ABSTRACT: The clinical spectrum of intra-abdominal fungal infections has not been systematically analyzed in the literature. Even though intra-abdominal fungal infections have been recognized with increasing frequency in the recent years, most clinical experience is limited to case reports or uncontrolled case series. These infections are more common than clinically recognized disease. The clinical presentation varies broadly depending on the organism and host's immune status, but it is frequently severe, difficult to treat, and associated with significant morbimortality. Predisposing factors, clinical characteristics, and advances in the management are discussed. Intra-abdominal fungal infections are increasingly important in clinical practice. Early recognition and a combined treatment approach, usually consisting of surgical intervention and systemic antifungal therapy, are required for improved outcomes.Current Opinion in Infectious Diseases 10/2013; 26(5):441-6.

ABSTRACT: An adult female, wild-caught red coachwhip snake (Masticophis flagellum piceus) was euthanized at the Phoenix Zoo due to severe neurologic signs. Necropsy and histopathology revealed an invasive liposarcoma of the vertebral column, which likely caused the neurologic signs. Histology of the small intestine revealed a granuloma with intralesional yeasts morphologically compatible with the genus Coccidioides. The diagnosis of coccidioidomycosis was confirmed with immunohistochemistry staining. Coccidioides posadasii is endemic to Arizona and is an important cause of disseminated fungal infections in mammals in this region. This is the first known report of intestinal coccidioidomycosis in a veterinary species and the second report of coccidioidomycosis in a reptile.Journal of Zoo and Wildlife Medicine 12/2013; 44(4):1094-7.

ABSTRACT: Blastomyces dermatitidis is a dimorphic fungus endemic to the midwestern, south-central, and southeastern United States known to cause disseminated infection in immunocompromised individuals. We report a case of B. dermatitidis peritonitis in a renal allograft recipient with new-onset ascites and cytomegalovirus encephalitis. Peritoneal blastomycosis is a rare clinical entity and, to our knowledge, this patient represents the first known case of peritoneal blastomycosis in a solid organ transplant recipient. We review the clinical characteristics of B. dermatitidis peritonitis as well as the literature on fungal peritonitis with emphasis on dimorphic fungal pathogens. Clinical features suggestive of fungal peritonitis include new-onset ascites, abdominal pain, and fevers, especially with antecedent or concomitant pneumonia. A high index of clinical suspicion, along with the use of culture and non-culture diagnostics, is needed for early diagnosis and prompt initiation of therapy.Transplant Infectious Disease 05/2014; 16(4).
