Tineas, also known as ringworm, is a common fungal infection that affects the skin, nails, and scalp. There are several synonyms for tineas, such as dermatophytosis, tinea infection, mycosis, and fungal infection. These terms reflect the nature of the infection and the organism responsible for causing it. The most common types of tineas include athlete's foot, jock itch, and scalp ringworm, which are all caused by different species of the same fungus. Treatment for tineas typically involves topical or oral antifungal medication, as well as good hygiene practices to keep the affected area clean and free of moisture.
