Lethal invasive mucormycosis: case report and recommendations for treatment

Area of Science:

• Mycology
• Infectious Diseases
• Pathology

Background:

• Invasive mucormycosis (IM) is a rare, aggressive fungal infection.
• It primarily affects immunocompromised individuals, often presenting with severe symptoms.
• Risk factors include conditions like asthma treated with steroids and undiagnosed diabetes mellitus.

Observation:

• A case report details a 73-year-old female with a cervical abscess, asthma on steroids, and undiagnosed diabetes mellitus.
• The patient experienced a fatal progression of the condition despite surgical intervention and antibiotic therapy.
• This highlights the aggressive nature of IM in susceptible individuals.

Findings:

• The case underscores the challenges in diagnosing IM, which can be mistaken for other conditions like necrotizing fasciitis (NF).
• Urgent histological examination of debrided tissue is vital for early and accurate diagnosis.
• Timely diagnosis facilitates prompt initiation of appropriate antifungal therapy.

Implications:

• Early histological diagnosis of IM is critical for effective management and improved patient outcomes.
• Distinguishing IM from NF through histology allows for targeted treatment, potentially preventing fatal progression.
• This case emphasizes the importance of considering IM in immunocompromised patients with rapidly progressing infections.
