title: Case report of subcutaneous entomophthoromycosis with retroperitoneal invasion.
abstract: The authors describe a case of entomophthoromycosis in a previously healthy patient, who presented with an abscess in the right buttock. After surgical drainage it evolved into a retroperitoneal tumor. The patient improved clinically after resection of the mass and ketoconazole treatment. The histopathological analysis showed the Splendore-Hoeppli phenomenon, suggesting Basidiobolus ranarum infection, a zygomycosis generally restricted to the subcutaneous tissue, with rare gastrointestinal involvement.
