Dermoscopy of a non-pigmented eccrine poroma
Journal Title: Journal of Surgical Dermatology - Year 2016, Vol 1, Issue 3
Abstract
Eccrine poroma is a benign adnexal tumor arising from cells of the outer layer of the acrosyringium and upper dermal eccrine duct. It generally appears as a solitary, slow growing, sessile, pink-to-red and well-circumscribed papule, plaque or nodule. It is usually located on the palms and soles but it may also develop on other locations. Its clinical appearance can resemble other types of tumors such as hypo- or amelanotic melanoma. Dermoscopy has improved the evaluation of skin tumors. In the case of eccrine poroma, there are some studies that have described its dermoscopic findings. These mainly focus on its vascular structures. We present an 82-year-old patient who developed a 2×3-cm eccrine poroma on his lower back. Dermoscopy demonstrated the presence of a polymorphous vascular pattern displaying mostly linear looped (irregular hairpin-like) and ―leaf-flower-like‖ vessels (―cherry-blossom‖ and ―chalice-like‖), with some resembling ―cactus-like‖ structures. Only a few linear coiled (glomerular) and linear helical (corkscrew) vessels were observed. Some of these vascular structures were surrounded by a whitish-to-pink halo. Moreover, some pink structureless areas were present. We highlight the finding of the ―leaf-flower-like‖ vessels, as these are vascular structures that have not been described in other types of skin tumors.
