Two patients were admitted to a major medical center in the southwestern United States. The first patient presented with chronic sinusitis. Hematoxylin and eosin stains of debrided material revealed granulation tissue, chro nic inflammation, and noninvasive, brownish septate hyphae. The second patient presented with leukemia and an erythematous cutaneous lesion. Biopsy of the lesion revealed septate hyphae, swollen hyphal elements, and hyphae with bizarre dilatations. What is the most probable etiology for both patients?
