All the following statements are true about pityriasis versicolor except
**Core Concept**
Pityriasis versicolor is a common skin condition characterized by macular hypopigmentation or hyperpigmentation, typically affecting the upper trunk and shoulders. It is caused by the overgrowth of lipophilic (fat-loving) yeast-like fungi, specifically Malassezia species, which are normally present on the skin surface.
**Why the Correct Answer is Right**
Pityriasis versicolor is indeed a superficial fungal infection that results from the proliferation of Malassezia species, which thrive in warm, oily environments. The condition is more common in individuals with oily skin, and the lesions often appear as hypo- or hyperpigmented macules due to the accumulation of melanin-inhibiting compounds produced by the yeast.
