Tinea cruris in Child
Tinea cruris is more common in postpubertal males. It rarely spreads to the penis, but if it does, it will be found only at the base of the penis.
Tinea cruris can be differentiated from cellulitis based on the location and the presence of scaling. In contrast to cellulitis, tinea cruris often occurs bilaterally.
In the immunocompromised patient, pruritus may be absent. There is an increased risk of all dermatophyte infections (tinea pedis, cruris, corporis, and faciale as well as Majocchi granuloma) in immunocompromised individuals.
A severe antifungal-resistant tinea has emerged in South Asia from the rapid spread of a novel dermatophyte species: Trichophyton indotineae. Terbinafine-resistant T indotineae infections have been reported in Asia, Europe, Canada, and the United States, including one case in New York City with no history of recent international travel.

- Scrotal favus is a rare dermatosis that presents with thick, white, cup-shaped scales on the scrotum. Most cases of scrotal favus are due to Nannizzia gypsea (previously known as Microsporum gypseum) and Trichophyton rubrum. Scrotal favus may co-exist with tinea cruris.
