Relapsing Polychondritis with Erythema Nodosum like Lesions - a Case Report

On examination, there was no evidence of hoarseness, dyspnoea, photophobia, hearing loss, ataxia and bony deformities. Investigations revealed a mild derangement of liver enzymes, while Rheumatoid factor and CRP were positive. Biopsy of the left ear pinna and leg nodules were done. Histopathology findings were similar from both sites showing a dense lymphoplasmacytic infiltrate, rich in histiocytes and plasma cells and associated with myxoid changes. Additionally, the biopsy from the ear pinna showed a complete absence of cartilage (See Fig 4).
