A rare tumor of the face: malignant nodular hidradenoma with dermoscopic features mimicking amelanotic melanoma

J Cutan Med Surg. May-Jun 2011;15(3):167-71. doi: 10.2310/7750.2011.10048.


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.
