  • Title: A case of relapsing polychondritis involving the tragal and the conchal bowl areas with sparing of the helix and the antihelix.
    Author: Khan JH, Ahmed I.
    Journal: J Am Acad Dermatol; 1999 Aug; 41(2 Pt 2):299-302. PubMed ID: 10426914.
    Abstract:
    We describe a 65-year-old white man with a 21-year history of recurrent, afebrile episodes of painful, tragal, conchal bowl and eyelid swelling accompanied by occasional conjunctivitis. The remainder of the auricle was not involved. Episodes were both self-remitting and responsive to intramuscular steroid injections. Cutaneous and cartilaginous tissues were examined histologically following a therapeutic debulking procedure. The histologic features included dermal edema, vascular dilatation, and small vessel inflammation with a dense polymorphous inflammatory infiltrate rich in eosinophils. Perichondrial inflammation and cartilage degeneration with fibrosis were characteristically observed. Bacterial cultures demonstrated normal flora. This case fulfills the revised diagnostic criteria of relapsing polychondritis. It demonstrates an unusual presentation within the disease spectrum of relapsing polychondritis with tragal and conchal bowl involvement and sparing of the helix and the antihelix.
