Auricular perichondritis is characterized by inflammation of the connective tissue surrounding the ear cartilage. It can result from various factors, including infections and autoimmune reactions, sometimes affecting the underlying cartilage. Notably, it typically spares the earlobe, which lacks cartilage, aiding in diagnosis.

Bilateral involvement often points to autoimmune-related conditions. Infections are indicated by purulent discharge from a wound. Common causes include ear piercings, trauma, surgery, or unknown triggers, often requiring thorough investigation.

This case involved a patient who had her ear pierced with an uncapped gun at a mall kiosk. Such shearing damage to the perichondrium can predispose to infection. Early diagnosis is vital, as erysipelas, relapsing polychondritis, and auricular perichondritis can cause similar symptoms.

Prompt treatment is crucial to prevent disfigurement and complications. Pseudomonas aeruginosa, often linked to injured cartilage, requires specific antibiotics like ciprofloxacin. Surgical procedures may be necessary in severe cases leading to necrosis and permanent deformity. Immediate observation and experience-based treatment are essential, leading to successful resolution in this instance with a 10-day regimen of 500 mg ciprofloxacin taken every 12 hours, resulting in a complete recovery within two days.
