Involvement of the External Ear by inflammatory Skin Diseases.Clin Dermatol 2026 Jun 04. [Online ahead of print]CD
Chronic inflammatory skin disorders cover both frequent and rare dermatoses. The etiopathology of these diseases is broad and ranges from genetic factors to environmental and life-style issues. In this review, we focus on affections of the auricle by the eczema group, psoriasis, and pityriasis rubra pilaris, autoimmune disorders like relapsing polychondritis and cutaneous lupus erythematosus, and juvenile spring dermatosis. The anatomy of this particular region may alter the clinical presentation, course and treatment options for those skin disorders. Atopic dermatitis, seborrheic dermatitis, and psoriasis may be indistinguishable from the clinical point of view. A careful medical history and examination of the whole skin may be the clue for diagnosis. In difficult cases, histopathology is essential. Epidemiologic data, etiopathology, diagnostic criteria, and treatment modalities are discussed. Knowledge of these manifestations on the outer ear are of importance not only for dermatologists, but general practitioners, pediatricians and Ear-Nose-Throat specialists to avoid unnecessary diagnostics, misdiagnoses, and delay in treatment.
