“…The incidence rate of subcorneal hematoma varies, 2,8 but it has been reported to occur frequently in patients performing sports with repeated stop-and-go movements, such as tennis, basketball, and soccer. 1,5,9 Clinical diagnosis of subcorneal hematoma may be sometimes difficult because acral melanoma, acral melanocytic nevi, angiokeratoma, pyogenic granuloma, and plantar warts with thrombosis must be considered in the differential diagnosis. It is noteworthy that in our study, five lesions were referred as possible melanomas by the examining clinician.…”

Background. Subcorneal hematoma is a pigmented skin lesion usually occurring on palms or soles after a trauma or sport activity. Clinically, it may exhibit overlapping features with acral melanoma or acral melanocytic nevi, leading to unnecessary excision of this otherwise harmless skin lesion. Objective. The objective was to describe the dermoscopic features in a series of subcorneal hematomas. Methods. Dermoscopic images of 15 subcorneal hematomas were evaluated for the presence of different colors and dermoscopic structures. Results. In our series, a red‐black hue was the most frequent color seen by dermoscopy (40% of the lesions) and a homogeneous pattern of pigmentation was the most frequent dermoscopic structure (53.3%). Remarkably, 40% of the lesions exhibited a parallel‐ridge pattern that is usually found in early melanoma of palms and soles. In 46.7% of the lesions, red‐black globules were additionally seen at the periphery as satellites disconnected from the lesion's body. Only two lesions showed either parallel‐furrow or fibrillar pattern. A scratch test performed in four lesions, allowed complete or partial removal of the pigmentation. Conclusion. Dermoscopic features of subcorneal hematomas may be similar to those observed in acral melanocytic lesions. Nevertheless, in most cases the correct diagnosis can be facilitated by the presence of a red‐black homogeneous pigmentation, often combined with satellite globules. A positive scratch test may be considered as an additional diagnostic clue.

“…The brown-black colour is due to extravasted haemoglobin and is most often seen in athletes who participate in sports with sudden stopping and starting on hard surfaces such as football, squash or tennis. Black heel seems to be especially common in basketball players due to their practise of slamming their feet against the floor in order to stop suddenly [2]. Black heel is usually asymptomatic, but raises the differential diagnosis of malignant melanoma.…”
