Elastotic nodules of the ears
Introduction:
Elastotic nodules of the ears are a rare mentioned pathology that usually is misdiagnosed as chondrodermatitis nodularis helicis because of its similar clinical and macroscopic appearance. Also it can simulate a neoplasm (mainly a basal cell carcinoma) or a focal accumulation of amyloid or monosodium urate (gout)
Clinical Presentation:
Usually it appears as a painful papule localized in antihelix but can also affects the helix of the ear. It can be billateral.
Histological features:
It is very simple. The epidermis is essentially normal and in the dermis there is a nodular accumulation of elastotic actinic material. There are some telangiectatic vessels beneath the epidermis. The cartilage is normal, without inflammation or necrosis.
