RESUMO
We describe a case of white grain eumycetoma of the foot of an Indian male caused by a slow-growing, poorly sporulating fungus that does not match any known agent of this infection. Histologic examination of a biopsy tissue specimen showed oval, lobular, white granules composed of hyaline, septate hyphae, and thick-walled chlamydospores. Culture of granules from a draining sinus yielded compact, very-slow-growing, poorly sporulating colonies producing a strong reddish brown pigment that diffused into the medium. The fungus was identified as a Cylindrocarpon sp. based on the development of rare cylindrical conidia borne from solitary phialides lacking collarettes, in addition to chlamydospores formed singly or in short chains.
