Abstract
- Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissues caused by pigmented or dematiaceous fungi that are implanted into the dermis from the external environment. The vast majority of infections are caused by Fonsecaea pedrosoi and Cladosporium carrionii. Several drugs, such as itraconazole, amphotericin B, terbinafine, have been tried with variable success and various therapeutic techniques, including radiotherapy, cryosurgery, electrodesiccation and surgical excision, can be applied as a further treatment. So far, there are five cases filed as chromoblastomycosis in Korea. Four of them are reported from the southern part of the Korea. Intralesional injection or occlusive dressing of Amphotericin B, and oral administration of intraconazole have been used for the treatment in reported cases. Now, we report firstly a case of chromoblastomycosis treated with terbinafine. A 54-year-old Korean teacher had 10 x 5.5 cm sized dark purple colored plaque with crusts 4 years earlier as a linear plaque after an injury by the thorns of wooden chair. A skin biopsy revealed pseudoepitheliomatous hyperplasia and dermal infiltration of mixed inflammatory cells and Touton type multinucleated giant cells with numerous sclerotic cells. Several clusters of sclerotic bodies were observed also within the giant cells. On the fungus culture, the colony showed slowly growing dark-brown colored heaped appearance in 4 weeks. Isolated fungus was identified as Fonsecaea pedrosoi. Because of partial response to 10 months' itraconazole treatment, the treatment regimen was changed to terbinafine 500 mg/d with marked improvement after 4 months.
