Description:
Background:Sweat gland neoplasms are rare neoplasms with less known dermoscopic features.Observations:By applying dermoscopy, we identified some common vascular features that have been defined for amelanotic melanoma such as hairpin vessels, dotted vessels, linear irregular vessels, glomerular vessels, and milky-red areas.Conclusion:Polymorphic vascular structures can also be seen in eccrine neoplasms. Further evaluations should be done to differentiate and identify the common dermoscopic features of other sweat gland tumors.
