ABSTRACT

A case of dermatophytic pseudomycetoma, in a patient with a history of recurrent lesions in the scalp, for over two years, is reported. Histopathological examination of the affected tissues revealed the mycelial aggregates or pseudogranules characteristic of the disease. Cultures of fresh tissues samples detected a fungus identified as Trichophyton tonsurans. Additional examinations failed to demonstrate lesions of tinea capitis, a probable source of the deep infection. Dermatophytic pseudomycetoma is an extremely rare form of dermatophytosis, and the rarity of such cases is the motive for the present communication.


É descrito um caso de pseudomicetoma dermatofítico, recidivante, em paciente com lesões no couro cabeludo. O exame histopatológico de uma das lesões mostrou, nos tecidos, os agregados micelianos ou pseudogrânulos, característicos da enfermidade. Dos tecidos frescos de outras lesões foi isolado o dermatófito Trichophyton tonsurans. Exames micológicos adicionais falharam em demonstrar a existência de tinea capitis, possível fonte do pseudomicetoma. A raridade dessa forma de dermatofitose profunda justifica a presente publicação.
