Tinea imbricata

Tinea imbricata (also known in parts of Indonesia as “Kaskado”) is a superficial fungal infection of the skin limited to southwest Polynesia, Melanesia, Southeast Asia, India, and Central America.^{[1]: 303 [2]} The skin lesions, often itchy, occur mainly in the torso and limbs.^[3] The name tinea imbricata is derived from the Latin for "tiled" (imbricatus) since the lesions are often lamellar.^[4] The lesions are often treated with griseofulvin or terbinafine.^[4]

The condition has also become known as "Tokelau" - the name apparently references the islands of Tokelau in the South Pacific.^[5]

The risk of developing tinea imbricata is probably inherited as an autosomal recessive trait.^[6][7]

Tinea imbricata is associated with Trichophyton concentricum.^[4]

Tinea pseudoimbricata

The term "tinea pseudoimbricata" synonymous with "tinea indecisiva", was coined to describe a form of tinea mimicking the concentric rings of tinea imbricata, but is caused by local or systemic immunosuppression.^[8] Since then, 3 cases of Trichophyton tonsurans have been associated with it,^[9] as well as Trichophyton rubrum which can trigger mycosis fungoides.^[10][11] Mixed infections with scabies have been described to produce tinea pseudoimbricata.^[12][13]

As of 2015 in India, corticosteroid–antifungal–antibacterial combinations sold as over-the-counter drug have led to an increase in chronic, recurrent, difficult to treat fungal infections of the skin, including tinea pseudoimbricata.^[14]
