Coexistence of Scleredema and Acanthosis Nigricans in a Patient with Diabetes Mellitus / 대한피부과학회지

ABSTRACT

Scleredema and acanthosis nigricans are two distinct dermatological disorders that have been reported in association with insulin resistance. Few reported cases have shown an association between scleredema and acanthosis nigricans. A 53-year-old obese woman with diabetes mellitus presented with a 4-year history of an indurated plaque on the nape and upper mid-back. She also presented with a 20-year history of hyperpigmented, velvety plaques on the neck and both axillae. We report a diabetic patient who developed scleredema and acanthosis nigricans.
