Tinea cruris - Anogenital in
See also in: Overview,Cellulitis DDxSynopsis

Tinea cruris is frequently pruritic. It is more common in postpubertal males. People at higher risk include those who have diabetes mellitus, are obese, recently visited a tropical climate, wear tight-fitting or wet clothes (including bathing suits) for extended periods, share clothing with others, or participate in sports.
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.
Trichophyton indotineae is an emerging dermatophyte characterized by extensive or atypical presentations and resistance to topical and oral therapies. Trichophyton mentagrophytes genotype type VII (TMVII) is an emerging strain that is typically spread through close contact, including sexual intercourse. It may lead to genital and buttock tinea as well as tinea corporis.
