Painful Nodular Growth of the Ear

Advances in the understanding of chondrodermatitis nodularis chronica helices: the perichondrial vasculitis theory

“…Chondrodermatitis nodularis chronica helicis was first reported by Max Winkler in 1915 who reported eight cases 3 . Soon after, Foerster 4 presented four identical cases which he had investigated independently without knowledge of Winkler’s work. Later in 1925, Foerster reported eight additional cases and described the clinical, microscopic and treatment of the condition 5 .…”

A large case series (100 patients) in the literature was published in 1954, 6 the authors broadly covered all clinical and histopathological aspects of the condition.…”

Our study builds upon this work and explores the vasculitis theory suggested by their observations and first suggested by Halter in 1936.…”

Chondrodermatitis nodularis chronica helicis

“…Early authors [2,3] held that the anatomy of the ear was important in pathogenesis. The external ear develops around the branchial groove by the appearance of six small tubercles which flatten out to mold the pinna [9].…”

Chondrodermatitis nodularis chronica helicis

“…Several larger studies [2,3,9] have charac terized it as a distinct clinicopathologic entity which typically presents as one (rarely several) painful, whitish-yellowish to red papule of 2-5 mm. It is often covered with a keratotic crust and found on the helix of the ears of middleaged men.…”
