White grain mycetoma caused by a Cylindrocarpon sp. in India

J Clin Microbiol. 2000 Nov;38(11):4288-91. doi: 10.1128/JCM.38.11.4288-4291.2000.

Abstract

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.
