Relapsing Polychondritis Masquerading as Auricular Pseudolymphoma: Case Report and Literature Review

Relapsing Polychondritis (RP) is a rare autoimmune disease associated with recurring inflammatory episodes predominantly affecting cartilage and other tissues throughout the body, including proteoglycan-rich structures. It is characterized by gradual deformation of tissue that leads to impairment of normal function. Areas involved include, but are not limited to, the respiratory tract, eyes, nose, joints, and vascular system. The inflammation targets cartilage, most commonly causing auricular and nasal chondritis but can involve cartilage throughout the body. Diagnosis of RP is often hindered by the vast variety of symptoms associated with this systemic disease and subtle symptomatology. In this paper, we demonstrate a case of relapsing polychondritis masquerading as pseudolymphoma and review recent literature relating to pathogenesis, diagnosis and treatment.
