Sweat gland neoplasms are rare neoplasms with less known dermoscopic features.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.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.
