Abstract:
Eccrine acrospiroma, better known as eccrine poroma, is a benign adnexal neoplasm of the skin. Its clinical aspect can masquerade as some other nodular and cystic lesions. The current dermoscopy literature offers very few case studies. Moreover, these very few examples present a totally different appearance pattern compared to the one we examined. Its homogeneous blue pattern suggested the better-known nodular malignant melanoma; in fact, this dermoscopic appearance was due to the Tyndall effect.
