Malassezia folliculitis is a skin condition caused by the yeast Malassezia. This yeast is a type of fungus that is naturally found on the skin of most individuals. However, in some cases, it can proliferate and cause a condition known as Malassezia folliculitis, formerly known as Pityrosporum folliculitis.

Causes

The primary cause of Malassezia folliculitis is the overgrowth of the yeast Malassezia. This can occur due to a variety of factors, including:

• Antibiotic use, which can disrupt the natural balance of microorganisms on the skin
• Immunosuppression, which can make the skin more susceptible to infections
• Hormonal changes, which can affect the skin's oil production and create a more hospitable environment for the yeast
• Excessive sweating, which can provide the moisture that the yeast needs to thrive

Symptoms

The symptoms of Malassezia folliculitis can vary, but often include:

• Small, red bumps or pustules on the skin, particularly in areas with a high concentration of oil glands such as the chest, back, and face
• Itching or soreness in the affected area
• A worsening of symptoms in hot, humid weather or after sweating

Diagnosis

Malassezia folliculitis is often misdiagnosed as acne, as the symptoms can be very similar. However, it can be distinguished by the presence of yeast in the follicles, which can be detected through a skin biopsy or culture.

Treatment

Treatment for Malassezia folliculitis typically involves the use of antifungal medications, either topical or oral. These work by killing the yeast or preventing it from growing. In some cases, changes to the individual's skincare routine or lifestyle may also be recommended to help prevent a recurrence of the condition.
