Scraping test for the diagnosis of acral subcorneal hemorrhage

Pigmented skin lesions of sudden onset represent a diagnostic challenge in dermatology. Especially in acral sites, a differential diagnosis between a melanocytic lesion and a subcorneal hematoma or subcorneal hemorrhage (SH) may be difficult. Dermoscopy is a useful tool to differentiate benign from malignant lesions, but sometimes it is not decisive.
