What is the difference between psoriasis and tinea?

Psoriasis is a chronic autoimmune skin condition characterized by red, scaly patches that can be itchy and painful, often affecting areas like elbows and knees. Tinea, commonly known as ringworm, is a fungal infection that presents as red, itchy, circular rashes with clear centers and can occur on various body parts, including the scalp and feet. While psoriasis is related to immune system dysfunction, tinea is caused by dermatophyte fungi. Treatment approaches also differ, with psoriasis often requiring topical steroids or systemic medications, while tinea is treated with antifungal agents.
