Abstract
INTRODUCTION: Sebaceous hyperplasia is a benign proliferation of the sebaceous gland. In this study, we tried to define the dermatoscopic features of sebaceous hyperplasia, which will help to minimize misdiagnoses. MATERIAL AND METHOD: Seventeen patients with 30 sebaceous hyperplasia lesions were included in the study. All the lesions were evaluated dermatoscopically. RESULTS: Cumulus sign, crown vessels, and milia-like cysts were detected in 100%, 86.6%, 53.3% of the lesions, respectively. In 80% of the lesions, the bonbon toffee sign was detected. CONCLUSION: During this study, we observed a feature with central umbilication surrounded by cumulus sign in 80% of our cases, and we named this entity as the 'Bonbon toffee sign', which resembled us 'bonbon toffee'. We think the 'bonbon toffee sign' is a simple and easily recognizable phrase, and it can be used as a new terminology in dermatoscopic diagnosis of sebaceous hyperplasia.
