Eccrine poroma: An unusual presentation and evaluation with the use of dermoscopy and optical-coherence tomographic imaging

Eccrine poromas (EP) are benign cutaneous adnexal neoplasms that commonly present as solitary plaques, papules, or nodules on the lower extremities. Both clinically, and on dermoscopy, EP can be hard to distinguish from other skin tumors, including amelanotic melanoma and eccrine porocarcinoma. Dermoscopy and optical-coherence tomography (OCT) are 2 noninvasive imaging devices that can increase the diagnostic accuracy of benign and malignant cutaneous diseases. Thus, understanding the dermoscopic features of EP and characterizing it on OCT imaging may help improve diagnostic accuracy.
