A peculiar case of large primary cutaneous Ewing’s sarcoma of the foot: Case report and review of the literature

Introduction Primary cutaneous extraskeletal Ewing’s sarcomas (ESs) are extremely rare tumors, limited to the skin and generally appear as a single small lesion, circumscribed mid-to-deep dermis or involving subcutis. Due to their rarity and morphological similarity to other cutaneous tumors, ESs are subject to being clinically and pathologically subdiagnosed.
