A 25-year-old female presents with a painful swelling in her right external ear canal. On examination, the canal is narrowed, and a furuncle is seen. What is the potential diagnosis and appropriate treatment?
This patient's symptoms are suggestive of an external ear canal infection known as otitis externa, specifically a localized form called furunculosis, typically caused by Staphylococcus aureus. Treatment generally involves warm compresses to facilitate drainage, topical antibiotics, and pain management. In some cases, incision and drainage may be required.
