Abstract
Polypoid melanomas are unusual, as are amelanotic ones.
Similarly, polypoid melanomas are not usually acral or amelanotic.
They can be challenging to diagnose clinically, as they may resemble
acral lentiginous nevus, polypoid Spitz nevus, eccrine poroma, schwannoma,
pyogenic granuloma, verrucous carcinoma, fibrosarcoma, basal
cell carcinoma, and pyoderma gangrenosum. We delineate a 64-yearold
woman with an acral amelanotic polypoid melanoma on her sole. It
was successfully removed surgically without limb amputation
