“…SH describes a traumatic rupture of the dermal papillary capillaries resulting extravasation of red blood cells into stratum corneum of the skin [1]. Many other terms, including intracorneal hematoma [2], talon nair [3], black heel [4], basketball heel [5], hyperkeratosis hemorrhagica [6] and tennisferse [7], have been used to define this condition. It is not always easy to diagnose SH correctly by unaided eye.…”

S ubcorneal hematoma (SH) means blood accumulation beneath the horny layer of the skin. SH usually occurs in the palmoplantar region as a consequence of blunt trauma. Differential diagnosis of the entity mainly includes acral lentiginous melanoma and acral nevi [1, 2]. Dermoscopy is a non-invasive and practical tool that recently has become one of the major diagnostic methods in daily dermatology practice. Dermoscopic features of many dermatological conditions have been well described. However, only one original study focusing on the dermoscopic findings of SH exists in the respective literature [1]. In this study, we aimed to describe dermoscopic findings of SH, which will facilitate the diagnosis by reducing the use of invasive procedures. MATERIALS AND METHODS This study included patients with subcorneal hematoma. All the patients were selected from the outpatient de-ABSTRACT OBJECTIVE: There are few studies investigating dermoscopic features of subcorneal hematoma, which is one of the imitators of acral melanoma. In this study, we aimed to describe dermoscopic findings of SH which will facilitate the diagnosis by reducing the use of invasive procedures. METHODS: This study included patients with subcorneal hematoma. Clinical, demographic and dermoscopic findings of all the patients were retrospectively reviewed. The diagnosis of subungual hematoma was confirmed using a positive scratch test in all of the patients. RESULTS: The findings showed that red-black (n=9, 45%) was the most common dermoscopic color followed by brown (n=4, 20%), red (n=3, 15%), black (n=2, 10%), brown-black (n=1, 5%) and red-brown (n=1, 5%). The most common pigmentation pattern was homogenous pattern (n=13, 65%). Eleven (55%) lesions showed globular pattern and eight (40%) lesions exhibit parallel ridge pattern. Eight (40%) lesions showed a combination of homogenous and globular patterns. The globules were disconnected from the homogenous pigmentation in six lesions. In two (10%) lesions, the globules were localized over the homogenous pigmentation. CONCLUSION: The presence of homogenous red to brown to black pigmentation combined with globules may lead to the correct diagnosis in a subcorneal hematoma. Scratch test may be a practical and minimal invasive diagnostic option to confirm the diagnosis in suspicious cases. To our knowledge, this is the most comprehensive study focusing on the dermoscopic aspect of the subcorneal hematoma.

“…In 1961, Crissey and Peachey 1 reported for the first time on calcaneal petechiae, which were defined as a pigmentation occurring on the heels of basketball players and interpreted as a traumatic bleeding caused by the intense sport activity. In the following years, several reports dealing with the same phenomenon were published and a number of different terms were used to define this traumatic rupture of the papillary capillaries with subsequent extravasations of erythrocytes in the cornified layer of the volar skin (pseudochromidrose plantaire, 2 talon noir, 3 basketball heel, 4 tennisferse, 5 black heel, 6 subcorneal hematoma, 7 and hyperkeratosis hemorrhagica 8 ). 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 …”

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.
