Aspergillus candidus eumycetoma with review of literature.

Mycetoma is a slowly progressive, chronic granulomatous infection of skin and subcutaneous tissues with involvement of underlying fasciae and bones, usually affecting extremities. In India, among mycetoma, the eumycetoma constitutes about 35% of cases. Hereby, we report the first case of eumycetoma caused by uncommon fungus, Aspergillus candidus. A 61 year old female presented to the Department of Dermatology with history of swelling of right foot associated with multiple firm nodules of approx. 1.5 × 1.5 cm each over dorsum of foot with discharging sinus containing white color granules. Biopsy of lesion on right foot on direct KOH examination revealed septate hyphae. Histopathology examination showed a histiocytic granuloma with fungal elements. Culture on Sabouraud Dextrose Agar grew white mycelial colonies which were identified to be Aspergillus species phenotypically. Genetic sequencing using Internal transcribed spacer gene, beta tubulin gene and Calmodulin gene was done and the isolate was identified to be Aspergillus candidus. Lesion was excised and patient was started on itraconazole. Timely identification and starting of antifungal treatment can help in reducing morbidity due to eumycetoma to a large extent. As newer and newer species of fungi are emerging as significant causative agents of human infections, it is pertinent to report such findings from epidemiological point of view.
