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. The objective was to describe the dermoscopic features in a series of subcorneal hematomas. Dermoscopic images of 15 subcorneal hematomas were evaluated for the presence of different colors and dermoscopic structures. 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. 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. IRIS ZALAUDEK, MD, GIUSEPPE ARGENZIANO, MD, H. PETER SOYER, MD, JEAN-HILAIRE SAURAT, MD, AND RALPH P.

The article presents a study which evaluates the dermoscopy features of small and large size basal cell carcinoma (BCC). Methods used in the study were dermoscopic images of 100 BBCs proven histopathologically and the examination of dermoscopy was performed through a polarized device. Results show that there were 43 lightly pigmented lesions, 46 as pigmented and 11 as heavily pigmented

The article reports on the case of a 30-year-old woman who developed two primary melanomas on her left lower extremity where atypical melanocytic skin lesions were seen in a quadrant or segmented distribution. She was diagnosed with a quadrant or segmental atypical nevus syndrome. Surgical excision of the nevi is impractical because it may not save the patient from the development of de novo melanoma within the affected site. Patients benefit from digital dermoscopic follow-up.
