Tinea corporis, commonly known as ringworm, is a superficial fungal skin infection caused by dermatophytes belonging to the genera Trichophyton, Epidermophyton, and Microsporum. They spread through direct contact with infected humans or animals, as well as contaminated fomites or soil. It can affect any age group, particularly post-pubertal children and young adults.
Since many diseases present with similar clinical presentations, understanding the differential diagnosis of tinea corporis can help avoid improper diagnosis and treatment. 1 This graphical abstract illustrates the differential diagnosis of tinea corporis.
