Tinea Corporis

Updated : February 28, 2024





Background

Tinea corporis is a skin condition that affects the body’s surface that is brought along by dermatophytes. Worldwide, tinea corporis is prevalent.

The lesions’ specific locations—which may affect the body’s trunk, neck, legs, and arms—are used to define it.

There are different names for dermatophyte disorders that infect different areas. These include the feet, hands, groin, and face.

Epidemiology

Tinea corporis is quite prevalent all over the world. The most frequent cause of peripheral fungal infections is dermatophytes. Fitted clothes, excessive heat, and high humidity all have links to more serious and frequent illnesses. Tinea corporis may also be more common in certain groups of people, such as children.

The two most prevalent dermatophyte diseases in Preadolescence children are tinea corporis and tinea capitis. Additionally, children are more susceptible to get zoophilic pathogens. Through contact with animals like cats and dogs, zoophilic illnesses can spread.

Patients with weakened immune systems are one vulnerable group. A variant of tinea corporis fungal folliculitis called Majocchi granuloma, which invades the deeper skin layers as opposed to the more superficial typical tinea corporis, is more common in immunosuppressed patients.

Anatomy

Pathophysiology

There are family and genetic dispositions to a fungal infection that may be mediated by certain flaws in innate and adaptive immunity, and not everyone is equally susceptible to microbial infection. A tendency to all dermatophytes may be seen in patients with low defensin beta 4 levels.

Inherent conditions including diabetes mellitus, lymphomas, immunocompromised state, Cushing syndrome, excessive sweating, or advanced age are some more risk factors. The prevalent belief is that dermatophytosis is controlled by a cell-mediated immune reaction.

Etiology

The dermatophytoses are caused by the dermatophyte’s capacity to cling to keratinized skin tissue (superficial fungal skin infections). Trichophyton, Microsporum, and Epidermophyton are the genera of dermatophytes that cause tinea corporis. In the past seventy years, Trichophyton rubrum has been the most frequent species to cause dermatophyte infestations.

Eighty to ninety percent of the strains are T. Rubrum. Microsporum audouinii and Trichophyton mentagrophytes are two further typical isolates. Direct transmission with the earth, animals, or the skin of other people or humans can result in infection. The most frequent etiologic organism depends on the mode of transmission in particular specific situations.

Direct transmission with a patient suffering from tinea capitis frequently results in tinea corporis secondary to Trichophyton tonsurans. T. tonsurans is the most prevalent cause of tinea capitis in the United Kingdom and the United States.

Additionally, T. tonsurans is frequently discovered in cases with tinea corporis gladiatorum.  Athletes who have frequent direct body contact may develop tinea corporis gladiatorum (classically wrestlers). Regular interaction with dogs or cats frequently results in Microsporum canis infection in patients with tinea corporis.

The prognosis is typically favorable with appropriate patient care compliance.
