A Psittacine bite and subcutaneous basidiobolomycosis: A case with a therapeutic challenge

Shivani Choubey et al. Med Mycol Case Rep. .

Abstract

Basidiobolus ranarum is a saprophyte that can be found in soil, rotting vegetables, and frogs' digestive tracts. Clinically, basidiobolomycosis presents as a persistent infection of subcutaneous tissue affecting the trunk and extremities in an immunocompetent host. We describe a case of subcutaneous basidiobolomycosis in a 56-year-old immunocompetent woman farmer by occupation residing at remote part of central India. This study highlights the traumatic implantation and zoonotic potential of fungal species. Clinical suspicion of fungal etiology and timely mycology laboratory diagnostic support is key to address such cases. This case is documented to emphasize the problems of compliance to treatment specially in remote and poor patients challenging the treatment with complete cure. 2012 Elsevier Ltd.
