Chondrodermatitis nodularis helicis (CDNH) is a non-neoplastic inflammatory and degenerative process of the external ear.
Effective treatment of chondrodermatitis nodularis chronica helicis using a conservative approach.
I suspect that this student will now have her mind cluttered up with the diagnosis chondrodermatitis
nodularis chronic helicis externa, which will do her very little good as she plans to be an anaesthetist.
The initial clinical differential diagnosis included a seborrheic keratosis, chondrodermatitis
nodularis helicis, basal cell carcinoma, and squamous cell carcinoma.
Chondrodermatitis nodularis chronica helicis is a small, painful, scaly nodule of the helix of the ear.
These findings were consistent with chondrodermatitis chronica nodularis helicis.
Analysis of the excised specimen detected epidermal ulceration with foci of necrosis in the hyaline cartilage, focal granulation tissue, and epidermal hyperplasia and hyperkeratosis; these findings were consistent with chondrodermatitis nodularis chronica helicis.
Based on physical examination findings, the differential diagnosis of chondrodermatitis chronica nodularis helicis includes basal cell carcinoma, squamous cell carcinoma, keratoacanthoma, and polychondritis secondary to an autoimmune disease.
Once malignancy is ruled out and a histologic diagnosis of chondrodermatitis nodularis chronica helicis is reached, the patient can be treated surgically or medically.
These procedures had been performed for the treatment of 21 skin cancers, four auricular hematomas, and 23 benign skin lesions with 11 different pathologies, including six cases of chondrodermatitis
nodularis chronica helicis and four cases of keloid.
The clinical and histologic differential diagnosis includes relapsing polychondritis and chondrodermatitis
nodularis chronica helicis (Winkler's disease).
Many features of chondrodermatitis
nodularis chronica helicis were present, but no degenerative cartilage was seen.
