Squamous Cell Carcinoma on Marginal Palmar Keratoderma
Abstract
Marginal palmar keratoderma is characterized by palmar keratoderma affecting the limits of the dorsal and palmar regions of ulnar and radial edges in patients with intense sun exposure. According to the literature it is not considered a pre-malignant lesion. Nevertheless, we report the first case of squamous cell carcinoma on marginal palmar keratoderma in a 57 year-old woman.
