Angiomyxome superficiel : Ã propos de quatre cas, dont deux lésions sous-unguéales

We report four cases of superficial angiomyxomas, including two cutaneous tumors and two subungueal tumors. Histological analysis revealed a recently described tumor, so called superficial angiomyxoma. This is a myxoid paucicellular tumor lobulated and poorly circumbscribed, containing numerous small blood vessels surrounded by a mixed inflammatory cell infiltrate with notable neutrophils. Those tumors are positive for CD34. The differential diagnosis includes myxoid neurothecoma, myxoid neurofibroma and, for ungueal tumors, superficial acral fibromyxoma.
