Tinea imbricata
Tinea imbricata
Tinea imbricata (pronunciation: /ˈtiːniə ɪmˌbrɪkəˈteɪtə/), also known as Tokelau is a dermatophytic infection caused by the fungus Trichophyton concentricum. The term "Tinea" is derived from the Latin word "tinea", meaning "worm", and "imbricata" is derived from the Latin word "imbricatus", meaning "overlapping", referring to the characteristic pattern of the skin lesions.
Etiology
Tinea imbricata is caused by the dermatophyte fungus Trichophyton concentricum. This fungus is geophilic, meaning it is naturally found in the soil. It is endemic in certain tropical regions, including parts of Asia, the Pacific Islands, and Central and South America.
Clinical Presentation
Patients with Tinea imbricata present with concentric, scaly rings on the skin. These rings often overlap, giving the skin a 'tiled' appearance. The lesions can be pruritic (itchy) and may cause discomfort.
Diagnosis
Diagnosis of Tinea imbricata is typically made through clinical examination and confirmed with a KOH test or skin biopsy. The fungus can be visualized under the microscope in skin scrapings.
Treatment
Treatment typically involves the use of antifungal medications, such as terbinafine, itraconazole, or griseofulvin. Topical antifungal creams may also be used.
