Abstract
Chondrodermatitis nodularis chronica helicis (CNCH) is a benign inflammatory disorder. It is characterized by a 4- to 5-mm large, painful, solitary nodule or papule on the helix. The pathogenesis of CNCH remains elusive. Differential diagnosis includes cutaneous malignancies such as squamous cell carcinoma (SCC) [1]. Diagnosis is mostly made clinically, but histopathological examination is recommended. Dermoscopy can help in the diagnosis of many tumoral or inflammatory skin disorders. To date, dermoscopic features of CNCH have not been defined. We sought to describe the dermoscopic findings in a series of patients with CNCH.
