title: [A very slow growing ankle swelling in a healthy male].
abstract: We describe the case report of a 66-year-old man with a very slow growing ankle tumour caused by a subcutaneous fungal abscess. Phaeoacremonium inflatipes, a member of the Dematiaceae family, was identified by needle puncture and culture of the non-odorous creamy yellow brown fluid. The fungal pseudocyst was surgically removed in toto and no further fungicidal drug therapy was required. Human infections by dematiaceous fungi causes subcutaneous phaeohyphomycosis, a rare, deep fungal infection of the skin and subcutaneous tissues usually acquired through traumatic skin lesions. In addition, systemic infections are reported, predominantly in immunosuppressed individuals.
