Relapsing Polychondritis in a Patient With Auricular Chondritis and Inflammatory Bowel Disease: A Case Report With Literature Review

Relapsing polychondritis (RP) most commonly presents as inflammation and degeneration of cartilaginous tissue in the auricles, nasal septum, and lungs (in severe instances). RP is a rare autoimmune condition associated with other autoimmune diseases in 30% of cases. The prevalence of gastrointestinal involvement with RP is tenuous; however, there is a growing collection of case studies associating auricular chondritis with concomitant inflammatory bowel disease (IBD), including both ulcerative colitis and Crohn’s disease. We report the case of a 35-year-old patient presenting with autoimmune pancreatitis, with a past medical history of Crohn’s disease, primary sclerosing cholangitis (PSC), and suspected RP. Although RP is rare, the disease’s multiple clinical presentations and recurrent episodic nature can cause significant diagnostic delays and are often overlooked by physicians. Thus, low disease prevalence may be due to under-recognition and under-reporting of disease symptoms. As RP is a clinical diagnosis, increased awareness of the disease presentation and clinical characteristics may increase disease recognition and improve treatment outcomes.
