Answer

Definition

Tinea versicolor, also known as pityriasis versicolor, is a superficial fungal infection of the skin caused by Malassezia species, which are lipophilic yeasts that are part of the normal skin flora.

Epidemiology

Pathophysiology

  • The condition is caused by Malassezia species, which are part of the normal skin flora.
  • These yeasts can transform into a pathogenic mycelial form under certain conditions, leading to the development of tinea versicolor.

Clinical course

  • Tinea versicolor is characterized by hypopigmented or hyperpigmented macules and patches on the skin, often on the trunk and proximal extremities.
  • The condition is usually chronic and can recur, especially in warm and humid climates.

Prognosis

Risk factors

In conclusion, tinea versicolor is a superficial fungal infection caused by Malassezia species, with a worldwide distribution. The condition is characterized by hypopigmented or hyperpigmented macules and patches on the skin, and it can recur, particularly in individuals with a history of the disease. The prognosis is generally good with appropriate treatment, although the condition can recur, especially in warm and humid climates.
