Therapeutic Options of Chondrodermatitis Nodularis Helicis

New tender, bleeding papule on the left ear

Chondrodermatitis nodularis helicis (CNH) is a painful, inflammatory condition that impacts the skin of the ear. It is commonly associated with pressure on the pinna causing a nodule that may have erythema, bleeding and exudate. We present a case of a woman in her 60s with a history of basal cell carcinoma who presented with a new tender spot on the antihelix of her left ear. The tenderness of the new spot forced her to switch from holding her phone to her left ear to using her right ear. A shave biopsy confirmed CNH and ruled out non-melanoma skin cancer. Although most prior cases report association with sleeping on the side of the affected ear, this case was attributed to cell phone use. It is important to remember that non-traditional sources of pressure can also lead to CNH.

Review of the Etiopathogenesis and Management Options of Chondrodermatitis Nodularis Chronica Helicis

Chondrodermatits nodularis chronica helicis (CNCH), first described by Max Winkler in 1915, presents as a sore nodule on the helix or antihelix of the external ear. In this paper, we review the etiopathogenesis and management options of CNCH. This condition has a multifactorial etiology; however, sustained pressure from sleeping on one side is the favored theory. Currently, there are many surgical and non-surgical methods of treating CNCH. Most practitioners recommend conservative measures first in their patients, such as pressure-relieving prostheses, prior to surgical treatment. Surgery is the gold standard of therapy with cartilage and wedge excisions yielding recurrence rates of about 10%. Carbon dioxide laser and photodynamic therapy are newer treatment modalities for CNCH, yet they have recurrence rates similar to conservative therapy. In conclusion, due to the high rates of CNCH recurrence, wedge resection is the suggested treatment for CNCH after conservative measures fail.
