Middle ear metastasis of thymoma

Area of Science:

• Oncology
• Otolaryngology
• Pathology

Background:

• Thymoma is a rare tumor originating in the thymus.
• Metastasis of thymoma to the middle ear is exceptionally uncommon.
• Understanding rare metastatic patterns is crucial for diagnosis and management.

Observation:

• A 54-year-old female patient with a history of thymoma presented with acute sensorineural hearing loss.
• Clinical and radiological evaluation revealed metastasis of thymoma to the middle ear.
• The hearing loss was noted in the ear contralateral to the primary thymoma site.

Findings:

• This case represents the first documented instance of thymoma metastasizing to the middle ear.
• The metastasis occurred alongside acute sensorineural hearing loss, highlighting a novel clinical presentation.
• Literature review confirmed the extreme rarity, with no prior reports found.

Implications:

• This case expands the known metastatic potential of thymoma.
• It underscores the importance of considering unusual metastatic sites in patients with thymoma.
• Further research may be warranted to understand the mechanisms and frequency of such rare metastases.
