Invasive fungal and fungal-like infections contribute to substantial morbidity and mortality in immunocompromised individuals. The incidence of these infections is increasing-largely because of rising numbers of immunocompromised patients, including those with neutropenia, human immunodeficiency virus, chronic immunosuppression, indwelling prostheses, burns, and diabetes mellitus, and those taking broad-spectrum antibiotics. Invasive fungal pathogens include primary mycotic organisms such as Histoplasma capsulatum, Coccidioides immitis, Blastomyces dermatitidis, and Paracoccidioides brasiliensis, which are true pathogens and inherently virulent.

Understanding deep cutaneous fungal infection requires not only reading many case reports and checking the typical clinical images of skin lesions, but also managing the patients properly to prevent misdiagnosis. Herein, I review my recent experiences with eight typical cases of deep cutaneous infections (including protothecosis and nocardiosis) in Japan. It is very important to do the four management processes; namely, KOH direct microscopic examination, skin biopsy, fungal culture, and microscopic examination of the histopathological specimen of PAS and Grocott staining.
