Pigmented Bowens disease mimicking malignant Melanoma: A case report

Abstract

Pigmented Bowens disease is an in situ squamous cell carcinoma, which is seldom reported in white patients. Herein we report a 20-year-old woman with type III skin, who had this lesion on the fourth finger of her right hand, similar to superficial malignant melanoma, clinically. Although dermoscopic evaluation could be helpful, correct diagnosis of non-melanotic origin is done by histological examination. In spite of its rarity, pigmented Bowens disease should be considered in the differential diagnosis of malignant melanoma.
