"Poroma-like" branched vessels with rounded endings in dermoscopy of basal cell carcinoma: a new unusual structure

We report the cases of three patients with basal cell carcinoma that showed branched vessels with rounded endings, a vascular pattern never described in basal cell carcinoma and previously associated with eccrine poroma. We also speculate about the meaning of this pattern and underline the importance of this atypical vascular presentation in the differential diagnosis of malignant melanoma.
