Geophilic Tinea Profunda after a Stay at a Swiss Lake: A Case Report

Abstract

Cutaneous infections with Nannizzia gypsea in Switzerland are very rare (only about 0.2% of all dermatophyte infections). We present the case of an impressive tinea profunda on the upper arm of a 53-year-old woman. In our patient, the source of infection was probably the sand and soil at a Swiss lake. This case report shows the importance of a correct diagnostic workup, as the infection can mimic an inflammatory dermatosis like psoriasis or eczema and thus lead to a diagnostic and therapeutic delay.
