What condition is characterized by small depigmented areas on the skin, especially on tanned skin?

Tinea versicolor is a fungal infection of the skin that leads to small, discolored patches that can appear lighter or darker than the surrounding tanned skin. This condition occurs due to an overgrowth of a type of yeast that is naturally found on the skin. It interferes with the skin’s ability to tan evenly and can result in spots that may be pale or more pigmented in comparison to the surrounding skin, especially noticeable after sun exposure.

Athlete's foot is a fungal infection that typically affects the feet, presenting as itching, burning, and flaky skin. It does not create the depigmented patches noted in the question.

Psoriasis is an autoimmune condition characterized by red, scaly patches on the skin that arise due to rapid skin cell turnover. While it can also affect tanned skin, it does not result in the depigmented patches indicative of tinea versicolor.

Eczema, or atopic dermatitis, manifests as inflamed, itchy, and red skin. It may cause discoloration but is primarily associated with dryness and irritation rather than the specific pattern of depigmentation seen with tinea versicolor.

Overall, tinea versicolor specifically explains the presence of small depigmented areas on the skin, particularly
