| Sumario: | Background: Eccrine poroma is a benign neoplasm that can mimick a malignant neoplasm dermoscopically. The characteristic vascular pattern of this tumor has not been established.
Objective: To evaluate dermoscopic features of non-pigmented eccrine poroma in Mexican patients.
Method: We retrospectively studied histologically proven cases of eccrine poroma from three Mexican hospitals analyzed by four dermoscopists.
Results: Thirteen cases were studied. A polymorphous vascular pattern was found in most cases. Four presented with irregular linear and branched vessels with semi-elliptical, or semicircular endings (“chalice-form” and “cherry-blossoms” vessels). Structureless pink-white areas were the most common other dermoscopic finding.
Conclusions: “Chalice-form” and “cherry-blossom” vessels have not been reported in other benign or malignant neoplasms and can be a useful clue to the diagnosis of non-pigmented eccrine poroma.
Due to the variability of dermoscopic patterns of eccrine poroma further studies are required to establish the specificity of our findings.
