Superficial angiomyxoma is an under-recognized lesion which encompasses the majority of lesions referred to in earlier literature as " cutaneous myxoma ". Most of the cases present as cutaneous papules or polypoid lesions and have a predilection for the head and neck region and the trunk.
It is a rare benign neoplasm characterized by a conglomerate of multiple, moderately to sparsely cellular angiomyxoid nodules with scattered small blood vessels. We present here a case of superficial angiomyxoma in a 22 year-old male and discuss the morphological features, both macroscopic and microscopic, which are helpful for distinguishing this tumor from other soft tissue tumors, especially cutaneous focal mucinosis, cutaneous myxoid cyst and aggressive angiomyxoma. We also discuss the disease entity `superficial angiomyxoma'.
