Bras. Med. Trop. [online]. 2001, vol.34, n.3, pp. 291-294. ISSN 0037-8682. http://dx.doi.org/10.1590/S0037-86822001000300011.
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.
