“…A second step consisted in defining this lesion in the spectrum of benignity or malignancy. In this regard, the scheme of Folpe et al was used [3][4][5][6][7][8][9][10][11]. The cPEComa had only one characteristic suggestive of possible malignancy, the infiltrative growth pattern, but other parameters such as necrosis, tumour size greater than 5 cm and vascular invasion were absent.…”

“…The tumor is classified as malignant based upon the presence of two high-risk, worrisome features: increased mitotic activity (with three mitoses per ten high-power fields) and scattered nuclear pleomorphism (demonstrated by high-grade nuclear atypia) (hematoxylin and eosin: B, 9 2; C, 9 20). Republished from [96] with permission from the University of California, Davis Department of Dermatology, Sacramento, California Cutaneous PEComa is extraordinarily rare; only 67 patients have been described: 60 with primary benign PEComa, 5 with primary malignant PEComa, and 2 with skin metastases from a malignant visceral PEComa. In contrast to systemic PEComa, the female-to-male ratio was only 2:1.…”
