Non‐melanoma skin cancer: an overindulged circumlocution articulating keratinocytic cancer

embryonic remnants or aneurysms, as smooth muscle and laminae elastica were observed in most lesions, while arteriovenous anastomoses and glomus cells were absent. Girard et al. also described arteriovenous shunts and small ascending spiraled muscular arteries, then considered feeder vessels. As in the patient described here, acral arteriovenous tumors arising in the setting of a port-wine stain likely result in vascular proliferation, especially veins, supporting the histogenetic theory proposed by Koutlas and Jessurun. In conclusion, we report a case of an acral arteriovenous tumor occurring within a facial port-wine stain of a 41-year-old man. The development of an acral arteriovenous tumor in this setting is rare and likely results from a vascular proliferation, especially veins.
