WebAbstract: Majocchi’s granuloma (MG) is a rare fungal infection of the dermis that is mainly caused by dermatophytes (in ≥95% of cases); the most frequently identified cause is anthropophilic Trichophyton rubrum. In the rest of the cases, the causes are non-dermatophytic fungi such as Aspergillus species. WebFactors driving this surge and subsequent decline in impetigo are unclear and are likely to reflect changes in the pathogenicity of the causative organism, host factors or antibiotic prescribing practices.
