[A very slow growing ankle swelling in a healthy male].

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.
