[Conventional and molecular diagnosis of cutaneous mycoses].

The clinical presentation of fungal infections of the skin, hair, and nails is varied and sometimes presents a confusing clinical picture. The main objective is to rapidly institute diagnostic measures to avoid delays in therapy with potential expansion of the infection. A variety of laboratory tests are required. Classical methods are based on microscopy, different culture procedures, and histologic examination. Genotypic approaches to detection and identification of fungal pathogens have become very rapid and sensitive, making them additional options for routine diagnosis.
