A Rare Tumor of the Face: Malignant Nodular Hidradenoma with Dermoscopic Features Mimicking Amelanotic Melanoma

Abstract

French

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.
