Abstract
We had a patient with Aspergillosis in the nasal and paranasal sinuses causing the formation of rhinoliths. The patient was a 64 year-old male, and his maxillary sinus was opened by surgery to remove lesions on June 23, 1995. During surgery we found rhinoliths in the maxillary sinus and nasal cavity, and submitted them to Grocott's stain for microscopic observation. The structure of the rhinoliths resulted from the clustering of degenerate hyphae, suggestive of a highly calcareous concretion of Aspergillus fungi. The rhinoliths, when observed by SEM, showed dense clusterings of hyphae on the cracked surface of the specimen, and the presence of hyphae in granular structures on the surface. The patient has suffered no relapse until now.
