Summary
Tinea imbricata, or Tokelau, is a rare fungal infection caused by Trichophyton concentricum. Its occurrence is linked to genetic, racial, and immunologic factors, with limited treatment access hindering control.
Area of Science:
- Dermatology
- Mycology
- Infectious Diseases
Background:
- Tinea imbricata, also known as Tokelau, is a superficial fungal infection.
- It is caused by the dermatophyte Trichophyton concentricum.
- The condition exhibits specific geographic distribution and is influenced by various susceptibility factors.
Purpose of the Study:
- To provide a comprehensive overview of tinea imbricata.
- To discuss its historical, epidemiological, and immunological aspects.
- To describe clinical presentation, differential diagnosis, and therapeutic challenges.
Main Methods:
- Literature review of tinea imbricata.
- Analysis of epidemiological data, including genetic and racial susceptibility.
- Review of clinical manifestations and treatment options.
Main Results:
- Tinea imbricata is an infrequent mycosis primarily affecting endemic regions.
- Genetic, racial, and immunologic factors contribute to susceptibility.
- Differential diagnosis includes emerging diseases like syphilis in immunocompromised individuals.
- Treatment options include griseofulvin and terbinafine, but access and behavioral changes complicate management.
Conclusions:
- Tinea imbricata remains endemic in specific regions like the South Pacific, South Asia, and South America.
- Migration and climate change may influence the disease's incidence and characteristics.
- Control and prevention are challenging due to limited treatment access and evolving population habits.

01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:20Candidiasis
Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...
01:15Antifungal Agents
Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...
01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
