What is the fungus name linked with tinea versicolor?

Malassezia is part of the normal community of microorganisms found on human skin. Tinea versicolor develops when this yeast grows in a way that changes the surface skin and its pigment. Heat, humidity, sweating, and oily skin can support that change, but the condition is not caused by being unclean.

The resulting patches are commonly flat and appear on the trunk, shoulders, neck, or upper arms. They may be lighter, darker, pink, or tan, with fine scaling or mild itch. The name alone does not diagnose a patch, so compare symptoms with [Tinea Versicolor](/conditions/tinea-versicolor/) and [White Patches On Skin](/symptoms/white-patches-on-skin/).

A clinician may identify the pattern by examination and use a surface test if another condition is possible. Treatment targets the excess yeast with a cream, wash, or, in selected cases, an oral medicine. Follow the recommended course rather than stopping when the colour first changes, and disclose pregnancy, breastfeeding, allergies, and regular medicines before treatment.

Keep skin dry after washing and change damp clothing. A [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) or [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) may be discussed depending on the area involved.

Arrange a review if the rash is painful, inflamed, crusted, rapidly spreading, or not improving with appropriate care. Prompt assessment is also sensible for fever, pus, blisters, or patches near the eyes. These features can point away from uncomplicated tinea versicolor.

Ask whether the appearance is consistent with Malassezia-related tinea versicolor, whether testing is needed, and whether pigment may remain after the yeast is controlled. Ask when [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/) would be considered and what safety checks apply.
