Spontaneous Resolution of Exercise-induced Hematomas Mimicking Pigmented Lesions on the Soles and Palms: A Case Series

Summary

Exercise-induced hematomas are a common condition that are caused by mechanical rupture of small blood vessels in the skin resulting in accumulation of blood in the extracellular space in the dermis. These hematomas often lead to diagnostic dilemmas in dermatological practice as they may resemble other conditions. The term talon noir (black heel) was coined to describe these hematomas as they are often blackish in appearance.

The clinical findings of subcorneal acral hematomas typically include the appearance of a bruise or a discolored purplish patch on the skin [Figure 1A] but may appear also as a black or brownish patch, raising a differential diagnosis of a melanocytic lesion. In this case series we illustrate an unusual presentation of acral hematomas that mimics melanocytic lesions.
