Pityriasis (Tinea) versicolor is a fungal infection caused by Malassezia furfur. It is benign, superficial, and localized to the stratum corneum.
It may present as chronic or recurrent infection and may occur in healthy individuals.
It is more common in summer than winter months.
It presents with multiple well-demarcated macules or patches and finely scaled plaques with hypopigmentation or hyperpigmentation, hence the term "versicolor".
Lesions are usually found on the upper trunk, chest, back and shoulders, and may extend toward the neck, face and arms.

Urogenital infections remain a major reason for women to visit their family physician and their subsequent referral to obstetrics and gynaecology or urology specialists. The association between abnormal vaginal microbiota and an increased risk of contracting sexually transmitted diseases (STDs), as well as an increased rate of preterm labour, indicates the need to better understand and manage urogenital health in women.

As such, there is a sound rationale for using probiotics to maintain female vaginal and bladder health.
