A yellow-green discoloration on the nail is an early indication of which type of nail disease?

A yellow-green discoloration on the nail often indicates the presence of a nail fungus, specifically an infection caused by fungi that can affect the nail plate and surrounding areas. This type of discoloration is one of the early signs of fungal infection, which can occur due to various factors such as moisture retention, trauma to the nail, or exposure to contaminated surfaces. Recognizing these signs early on is crucial for effective treatment, which may include antifungal medications and proper nail hygiene.

While nail fungus and onychomycosis are closely related, onychomycosis specifically refers to a broader category of nail fungal infections. Psoriasis and eczema generally manifest with different symptoms and would not typically present with yellow-green discoloration. Understanding these distinctions helps in recognizing and diagnosing nail conditions accurately.
