INTRODUCTION

Tinea nigra is a superficial mycosis caused by the dematiaceous, yeast-like fungus Hortaea werneckii. The infection most often presents as an asymptomatic, hyperpigmented macule or patch on the palm (picture 1A-C). Less frequently, tinea nigra occurs on the soles of the feet or in other locations (picture 2A-C). The course of tinea nigra tends to be chronic; however, the infection resolves quickly with appropriate treatment.

The clinical features, diagnosis, and management of tinea nigra will be reviewed here. Other cutaneous fungal infections are reviewed separately.
