Chondrodermatitis nodularis chronica hefcis et antihelicis

Chondrodermatitis nodularis chronica helicis in monozygotic twins

“…Although the aetiology of CNCH is unknown, triggering factors have been described including trauma, actinic or cold injury, cartilage degeneration, pressure during sleep and prominence of the antihelix 1 …”

“…CNCH can be managed either surgically or nonsurgically. Non‐surgical options for CNCH include topical/intralesional corticoids, topical bacitracin and injectable collagen (suggesting a possible benefit produced by cushioning of the underlying cartilage) 1 . These nonsurgical procedures have a greater chance of recurrence than the surgical approach.…”

“…These nonsurgical procedures have a greater chance of recurrence than the surgical approach. Surgical methods include the use of CO 2 lasers, curettage of the cartilage, excision of the nodule by removal of the skin and affected cartilage, or excision of the nodule alone 1 . Surgical excision remains the gold standard of CNCH treatment 1 …”

“…Chondrodermatitis nodularis chronica helicis (CNCH) (Winkler’s disease) was described by Winkler in 1915, who believed that the condition was due to degenerative changes in the cartilage, acting as an inflammatory stimulus on the skin 1,2 . Munnoch et al.…”
