Two cases of tinea pedis caused by Scytalidium hyalinum.

Two cases of tinea pedis due to Scytalidium hyalinum, the first to be described in Italy, are reported. The patients were a 41-year-old woman and a 35-year-old man who had spent periods in the Caribbean. The clinical manifestations were indistinguishable from those caused by dermatophytes. In the women they were striking with 'moccasin foot' type lesions, whereas in the man they were less evident, with minor plantar desquamation and interdigital maceration. Diagnosis was based on direct mycological microscopic examination and culture. Clinical and mycological remission were obtained with systemic itraconazole therapy. These cases are reported because infections caused by Scytalidium hyalinum are rare in Europe and their clinical and mycological diagnosis, as well as therapy, may be problematic.
