title: Myxoid stroma and delicate vasculature of a superficial angiomyxoma give rise to the red planet sign.
abstract: Superficial angiomyxomas are uncommon benign mesenchymal tumors. They often recur locally if partially removed. This case report demonstrates not only the characteristic pathological findings of a superficial angiomyxoma in a 33- year-old man, but also shows a unique dermatoscopic image, which in our estimation resembles a celestial red planet such as the blood moon seen during a lunar eclipse. We propose to call this the "red planet" sign for a superficial angiomyxoma on dermoscopic examination.
