Ear growth

A shave biopsy of the lesion was performed and it confirmed the diagnosis of chondrodermatitis nodularis helicis (CNH).

CNH is an inflammatory process that most commonly occurs on the helix of the ear but can also occur on the antihelix and, rarely, on other areas of the ear. It generally manifests as a firm nodule with surrounding erythema that may be painful only when pressure is applied. Patients may describe bleeding, ulceration, and exudate. They will usually report discomfort from sleeping on the affected side.

The pathogenesis of CNH is poorly understood but is thought to be related to vasculitis and inflammation from prolonged pressure to the affected ear during sleep or from devices that are worn in or around the ear (eg, hearing aids, headphones). Other factors such as actinic damage or ear trauma have also been described. Histopathologic studies have identified arteriolar narrowing with ischemic changes and necrosis of cartilage causing localized inflammation.¹

The differential diagnosis for this lesion includes nonmelanoma skin cancer, as well as tophaceous gout and seborrheic keratosis.

There are multiple conservative treatment options. One option is to relieve pressure by sleeping on the unaffected side or using commercially available pillows with a cutout or window where the affected ear can rest. Pharmacologic treatments include topical nitroglycerin¹ and intralesional collagen or corticosteroid injections. If previous treatments are unsuccessful, consider surgical excision of the affected tissue and curettage of the underlying abnormal cartilage. Recurrence is possible with both conservative and surgical treatment.

This patient was counseled on the benign nature of her biopsy findings and treatment options were discussed. She elected to proceed with pressure-relieving measures when sleeping and planned to follow up if there was no improvement.
