Invasive nasal and paranasal mucormycosis in a patient with severe dengue fever and multiple risk factors: A case report and literature review.

Mucormycosis is a rare, life-threatening opportunistic fungal infection with high mortality rates that primarily affects immunocompromised patients. The co-occurrence of dengue fever and mucormycosis is extremely rare, with only a few cases reported worldwide. We report a case of a 50-year-old female diagnosed with mucormycos following dengue fever. To our knowledge, this is the first case report of invasive rhino-orbital mucormycosis following severe dengue fever in Vietnam. This case emphasizes the importance of close monitoring for opportunistic infections in patients with severe dengue fever and the necessity of combining antifungal therapy with surgical debridement to improve outcomes.
