Abstract:
A case of subcutaneous alternariosis caused by Alternaria alternata is reported in a 52-year-old male who underwent kidney transplantation 1 year earlier. The infection manifested as a vegetating mass about 7 cm in diameter on the right forearm. Histological examination with Grocott staining and periodic acid-Schiff diastase revealed fungal spores and hyphae with chronic granulomatous inflammation. Biopsy fragments inoculated on Sabouraud-glucose agar with chloramphenicol produced colonies which were identified as Alternaria alternata on the basis of macroscopic and microscopic characters.
