General Considerations P boydii is a mold that is capable of causing infection in immunosuppressed patients and less frequently in immunocompetent patients. Overall, infection with P boydii is rare. A. Epidemiology. Although a relatively common environmental mold, P boydii is a rare cause of human disease. It can be easily recovered from soil, water, and manure. Both community and nosocomial acquisition have been …

Although uncommon, Aspergillus sinusitis is related to the immune status and immunologic response of the host. A. Signs and Symptoms. In the severely immunosuppressed or neutropenic patient, Aspergillus sinusitis or rhinosinusitis may occur. Symptoms include headache, toothache, nasal congestion, purulent nasal discharge, and sinus or eye pain. Fever is commonly encountered. The nasal mucosa may exhibit hyperemia or necrosis that may extend into the mouth. Ptosis and loss of extraocular eye movement are prominent signs, indicating extensive invasion into the orbit. …
