A case of relapsing polychondritis with perichondrial IgG and C3, dermoepidermal IgG, and a coexisting pseudocyst of the auricle is reported. The use of direct immunofluorescence testing in establishing a diagnosis of relapsing polychondritis and the expected findings are reviewed. In some cases direct immunofluorescence may allow a diagnosis of relapsing polychondritis before clinical criteria or a routine histologic evaluation suggests a definite diagnosis.
