Primary Extraskeletal Ewing sarcoma of the foot with extensive skeletal and pulmonary metastasis: A rare case report

Introduction: First -degree cutaneous extraskeletal Ewing's sarcomas (ESs) are incredibly uncommon skin-specific tumors that often present as a single, tiny lesion that is restricted to the mid-to-deep dermis or involves the subcutis. ESs can be clinically and pathologically misdiagnosed because of their rarity and physical resemblance to other cutaneous cancers.

Case presentation: A 47-year-old nonsmoking woman was admitted after being transferred from a nearby hospital to check her right foot pain that had been present for three months and was significantly numbing the same side. Only a few lone cases or brief series are reported in the current literature. The typical description of ESs is that they are tiny masses with positive clinical behavior.

Discussion: Despite being a rather common location, only infrequent and minor ESs of the foot are present. After the recommended operation and subsequent histology analysis, we identified this uncommon sort of tumors.

Conclusion: Although it's rare, it's very important to consider this tumor in the differential diagnosis of foot pain with/without visible and/or palpable cutaneous lesion.
