Three cases of @entity571 due to dematiaceous fungi are reported. The first case, a @entity1511 complicating prosthetic valve @entity364 responded only to the association of @entity2379 and @entity3102 . The second @entity1 had @entity626 due to Phialophora parasitica resistant to medical and surgical treatment after renal transplantation. These two cases are the first and the second known reports of clinical infection with these fungi. The third @entity1 had @entity571 complicating a @entity272 by a thorn prick. This was cured by surgical excision and 3 months' medical treatment. These cases of @entity281 followed subcutaneous @entity733 . Deep tissue infections with dematiaceous fungi with osteoarthritic involvement are very rare (6 cases of Drechslera and 8 cases of Phialophora have been reported). These fungi are opportunist saprophytes of plants in subtropical regions. They are characterised on culture by their @entity2118 and microscopy shows septated filaments. Cutaneous effraction is the usual portal of entry in @entity1 ; @entity1 commonly have @entity308 of their immune systems. @entity571 is generally due to local extension of a @entity733 . The functional sequellae can be very serious. Treatment comprises surgical excision of the infected tissues with antifungal drugs which may have to be given in association.
