A 56-year-old female, originally from Suriname, with an otherwise unremarkable previous medical history was found to have a renal mass highly suspicious for renal cancer for which a nephrectomy was performed. Within the kidney, a tumourous mass was found which, on histological examination, showed an inflammatory pseudotumour caused by Histoplasma capsulatum. Further investigations revealed an idiopathic CD4+ lymphopenia. Mass lesions mimicking a malignant tumour caused by infection with Histoplasma have rarely been described. To the best of our knowledge, this is the first report of a Histoplasma-associated inflammatory pseudotumour mimicking cancer occurring in the kidney.
