Synopsis

Tinea corporis is a localized inflammatory skin condition due to fungal colonization of the superficial epidermis. The most commonly implicated species is Trichophyton. Fungal organisms are transmitted to children by direct contact with those infected or through fomites. Majocchi granuloma is caused by organisms invading the hair follicle or shaft of hairs on skin other than the scalp with a secondary granulomatous perifolliculitis. Varying location presentations include tinea capitis (scalp), tinea faciei (face), tinea pedis (feet), tinea manuum (hands), and tinea cruris (crural folds).

Disseminated tinea may be seen in patients with immunosuppression, diabetes, Cushing syndrome, and malignancy. Majocchi-like granulomas, deep ulcerated fungal infections, severe tinea capitis and corporis, and fungal nail involvement are characteristic of an inherited deficiency of CARD9 (caspase recruitment domain-containing protein 9), an inflammatory cascade-associated protein. The disorder is autosomal recessive and is most common in North African countries including Algeria, Morocco, and Tunisia. The infections usually begin in childhood and are caused by Trichophyton rubrum and Trichophyton violaceum. Lymphadenopathy, high IgE antibody levels, and eosinophilia are common, and the disorder can be fatal.

Tinea imbricata is a distinct form of tinea corporis caused by Trichophyton concentricum, which is prevalent in tropical locales such as Central and South America, the South Pacific, and Southeast Asia. This form has been reported in children as well.

Tinea indecisiva (tinea pseudoimbricata) is tinea corporis that mimics tinea imbricata. These cases are not caused by Trichophyton concentricum but rather by other Trichophyton or Microsporum species. There is usually underlying immunosuppression in patients with tinea indecisiva.
