What is Majocchi granuloma?
What does Majocchi granuloma look like?
Majocchi granuloma presents with an irregular red, scaly plaque in which there are follicular papules, pustules and nodules. It is usually found on one lower leg.
What is the cause of Majocchi granuloma?
Majocchi granuloma is most often caused by Trichophyton rubrum. Sometimes other fungi are found on culture, including:
- Trichophyton mentagrophytes
- Trichophyton violaceum
- Epidermophyton floccosum.
Associated factors leading to deep follicular infection may include:
- Topical steroids (resulting in tinea incognito)
How is Majocchi granuloma diagnosed?
Suspicion is raised due to its clinical appearance.
To confirm the diagnosis, scrapings and hair samples may be taken from the affected area for microscopy and fungal culture (mycology). Granulomatous inflammation is found on skin biopsy.
What is the treatment for Majocchi granuloma?
The recommended treatment for Majocchi granuloma is a 4-6 week course of oral antifungal agent.
Topical antifungal agents may not be effective due to deep invasion of fungus into the hair follicle.
