Facial chromoblastomycosis in sub-Himalayan region misdiagnosed as cutaneous leishmaniasis: brief report and review of Indian literature.
(49/59)
Cases of chromoblastomycosis, although not uncommon, have rarely been reported in the literature from our region. These are usually misdiagnosed as cases of cutaneous leishmaniasis because we reside in an endemic region for this disease. We present herein patients with facial chromoblastomycosis. They were treated with long-term sodium stibogluconate, but showed no response to therapy. A biopsy revealed these to be cases of chromoblastomycosis, after which the patients were started on antifungal agents. There was marked improvement after the correct treatment was initiated. (+info)

Non-healing verrucous plaque over upper limb for 1 year in a tea garden worker.
(51/59)
A 55-year-old tea garden worker presented with a slowly growing verrucous plaque on the right arm. The diagnosis of chromomycosis was confirmed by the identification of brown sclerotic bodies in a skin biopsy. (+info)
Sporotrichoid chromomycosis.
(52/59)
Chromomycosis is a chronic fungal skin infection. It manifests frequently by warty or vegetative lesions in exposed areas, most often secondary to trauma. The diagnosis, nevertheless, is confirmed by the presence of fungi in the mycological examination. In fact, the treatment remains a challenge given its recalcitrant nature. (+info)
Immunochemical characterisation of antigens and growth inhibition of Fonsecaea pedrosoi by species-specific IgG.
(53/59)
Antigens of Fonsecaea pedrosoi, the most common agent of chromomycosis, were characterised by immunoprecipitation with a rabbit antiserum raised against the cell-protein extract and serum from an infected patient. Thirteen antigens were commonly detected and, as some of these antigens could be iodinated, they may be present in the fungal cell wall. Purified IgG from the rabbit antiserum was shown to produce a 50-60% inhibition of fungal growth. Some of the antigens characterised may be important in relation to the stimulation of protective immunity against chromomycosis. (+info)
Role of the fungal cell wall in the granulomatous response of mice to the agents of chromomycosis.
(54/59)
Mice were given, intraperitoneally, inocula of a cell-wall preparation and fractions thereof from Fonsecaea pedrosoi, F. compactum, Cladosporium carrioni and Phialophora verrucosum. Large doses of cell-wall preparation, with or without trypsin treatment, produced a pronounced loss of body weight, a granulomatous reaction and, sometimes, death. After extraction of the cell wall preparation with 1N NaOH, three fractions were obtained: an alkali-insoluble fraction 1; an alkali-soluble acid-insoluble fraction 2; and an alkali- and acid-soluble fraction 3. Intravenous administration showed that only fraction 1 induced a granulomatous reaction and death in mice. (+info)
Mycoses imported from the West Indies. A report of three cases.
(55/59)
There have been isolated case reports of deep fungal infections from the Caribbean area but little is known about the distribution of mycoses there. Three cases, one of mycetoma, one of chromomycosis, one of histoplasmosis, are described. Their management and the advantages and disadvantages of treatment outside the area of origin are discussed.

Chromoblastomycosis (possibly Cladosporium) of the breast in an English woman.
(56/59)
A case is reported of an English woman who presented with a mass in the breast which was locally excised. Histological studies revealed a giant-cell granulomatous inflammation involving the duct system and a fungus showing brown pigmentation was demonstrated in the lesions. This was not grown in culture but the morphological appearance suggested classification in the genus Cladosporium. The relation of this to the more usual forms of cutaneous chromoblastomycosis is discussed. (+info)
