Chapter 21. Dermatophytosis

Course

Dermatophytosis is common, especially the scaly papules, papulovesicles, and vesicles of “athlete’s foot.” As most people who have that condition know, in the absence of treatment, its lesions come and go for years. Some expressions of dermatophytosis are self-limited, such as the infundibulocentric lesions of Majocchi’s granuloma and, episodically, of kerion. Other manifestations, however, are tenaciously persistent, like onychomycosis and dermatophytosis in an immunosuppressed patient. In that latter circumstance, lesions of a superficial fungal infection may be widespread and chronic.
