Chondrodermatitis nodularis chronica helicis

Chondrodermatitis nodularis chronica helicis is a small, nodular, tender, chronic inflammatory lesion occurring on the helix of the ear, most often in men.[2]: 610  it often presents as a benign painful erythematous nodule fixed to the cartilage of the helix or antihelix of the external ear.[3] Although the exact cause of the condition is unknown, it has been linked to head pressure on the ear while sleeping. Treatment options include the use of pressure-relieving devices or, in cases where that is not an option, surgery.[4]
