Allergic fungal otomastoiditis: a case report

Abstract:
Allergic mucin is described as thick, peanut butter-like mucus impacted in the paranasal sinuses of patients with allergic fungal rhinosinusitis. The presence of allergic mucin in the middle ear has never been reported. We encountered a 65-year-old female with allergic mucin found impacted in her left middle ear and mastoid cavity during revised tympanoplasty surgery at our institute. Bilateral endoscopic sinus surgery performed 3 months later showed no evidence of fungal infection or allergic mucin in her paranasal sinuses. We report the case herein and propose the term allergic fungal otomastoiditis for this disease entity.
Insights
A rare case of allergic fungal otomastoiditis is presented, involving thick, peanut butter-like allergic mucin found in the middle ear and mastoid. This condition, previously unreported, was observed in a patient without paranasal sinus fungal infection.
Area of Science:
- Otolaryngology
- Mycology
- Pathology
Background:
- Allergic fungal rhinosinusitis is characterized by allergic mucin in paranasal sinuses.
- The presence of allergic mucin in the middle ear is not previously documented.
Observation:
- A 65-year-old female presented with allergic mucin in the left middle ear and mastoid cavity during surgery.
- Subsequent endoscopic sinus surgery revealed no fungal infection or allergic mucin in the paranasal sinuses.
Findings:
- This case represents the first reported instance of allergic mucin impacting the middle ear and mastoid.
- The distinct clinical presentation suggests a novel disease entity.
Implications:
- Proposes the new term "allergic fungal otomastoiditis" for this condition.
- Highlights the need to consider middle ear and mastoid involvement in allergic fungal diseases.
- May prompt further research into the pathogenesis and diagnosis of allergic fungal otomastoiditis.
