Solitary Cutaneous Myxoma

ABSTRACT

A solitary cutaneous myxoma, referred to as superficial angiomyxomas, is relatively uncommon benign myxoid soft tissue tumors. The lesion usually present on the head, neck, and trunk of adults as a slowly growing asymptomatic nodule. Herein, we describe a case of a pedunculated solitary cutaneous myxoma arising on the vertex of a 48-year-old man, but with no evidence of Carney syndrome. Histologically, the tumor was composed of vascular, mucinous matrix with a network of fine collagen and reticulin fibers, containing stellate and spindle-shaped fibroblasts. There was no evidence of malignancy
