Overview
Malassezia infections encompass conditions such as pityriasis versicolor, seborrhoeic dermatitis, and Malassezia folliculitis, characterized by skin manifestations due to Malassezia yeasts overgrowth 1.Diagnosis
Clinical presentation guides initial diagnosis
Microscopy or culture of skin scrapings can confirm Malassezia presence 1
No specific grading system universally recommended 1Management
Pityriasis versicolor and Seborrhoeic Dermatitis:
- First-line: Topical antifungal agents (e.g., azoles, allylamines) 1
- Adjunctive: Short course of topical corticosteroids or calcineurin inhibitors for inflammation 1
Malassezia Folliculitis:
- Systemic antifungals may be more effective; combination with topical treatments can be favorable 1
Refractory or Widespread Lesions: Systemic antifungal therapy 1
Maintenance Therapy: Often necessary to prevent relapses 1Special Populations
Pregnancy: Specific recommendations not detailed in provided abstracts 1
Pediatrics: No specific guidance provided in the abstracts 1
Elderly: No distinct considerations mentioned 1
Comorbidities: No specific adjustments to treatment based on comorbidities noted 1Key Recommendations
Use topical antifungal medications as first-line treatment for pityriasis versicolor and seborrhoeic dermatitis (Evidence: Strong 1)
Incorporate short-term topical corticosteroids or calcineurin inhibitors for managing inflammation in seborrhoeic dermatitis (Evidence: Moderate 1)
Consider systemic antifungal therapy for widespread or refractory cases (Evidence: Moderate 1)
Maintenance therapy is recommended to prevent relapses (Evidence: Expert opinion 1)
For Malassezia folliculitis, systemic antifungals may be more effective; combination therapy with topical treatments can be beneficial (Evidence: Weak 1)References
