PITYRIASIS (TINEA) VERSICOLOR
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.

  • Treatment failure in primary care setting
  • Consideration of oral antifungal therapy in children <12 years
