Pityriasis Versicolor
Pityriasis versicolor is a very common fungal infection of the skin. It is caused by an overgrowth of the yeast fungus called Pityrosporum ovale (Mallassezia furfur).
This yeast is normally found on the human skin and only becomes troublesome under certain circumstances, such as a warm and humid environment. It is occasionally referred to by its colloquial Hawaiian moniker, "haole rot". It can affect any part of the body but generally involves the trunk and arms. Pityriasis Versicolor condition is treated with antifungal ointment. This common fungal disease is most prevalent in the tropics where there are high humidity and high temperatures and frequent exposure to sunlight. Several studies have addressed the frequency of tinea versicolor based on sex, and no dominance of either sex is apparent. Tinea Versicolor is known to be characterised by characterized by hypopigmented or hyperpigmented macules and patches on the chest and the back.
Pityriasis versicolor (PV) is a chronic asymptomatic scaling dermatosis associated with the superficial overgrowth of the hyphal form of Pityrosporum ovale, characterized by well-demarcated scaling patches with variable pigmentation, occurring most commonly on the trunk. The term 'pityriasis' is used to describe skin conditions in which the scale appears similar to bran. The multiple colours arising in the disorder give rise to the second part of the name, 'versicolor'. It sometimes called 'tinea versicolor', although the term 'tinea' should strictly refer to infection with a dermatophyte fungus .

The sweat is allowed to evaporate, and showering is delayed for a day, leaving a film of the medication on the skin
- Recurrence is common and may be reduced by intermittent application of topical agents (such as tea tree oil ) or adding a small amount of anti-dandruff shampoo to water used for bathing.
- Topical antifungal medications - containing either 2.5% selenium sulfide (Selsun shampoo in UK, but not Selsun Blue which contains only 1%) or 2% ketoconazole ( Nizoral ointment and shampoo) applied to dry skin and washed off after 10 minutes, repeated daily for 2 weeks.
