Abstract:
Majocchi's granuloma is a well recognized but uncommon infection of dermal and subcutaneous layers that is caused by fungal organism. It often presents as plaques and papules on areas where trauma is common. Majocchi's granuloma appears usually in immunocompromised patient but can also appear in immunocompetent patient. Tinea incognito appears in various forms of skin diseases, but it is rarely presented as Majocchi's granuloma. We report a case of trichophytic granuloma of the knee caused by Trichophyton(T.) rubrum in a 70-year-old male, who showed a pruritic, 7.0 × 2.0 cm sized, erythematous scaly patches with multiple papules on the right knee for 2 months. Fungal culture of the biopsy specimen grew out typical white cottony colonies of T. rubrum. The nucleotide sequence of internal transcribed spacer for clinical isolate was identical to that of T. rubrum strain ATCC 52013 (GenBank accession number KX092384.1). Histiologic examination showed chronic granulomatous inflammation and fungal elements in the dermis. After one month of itraconazole 200 mg/day and sertaconzole cream treatment, the lesion was completely cleared.
