Ewing’s Sarcoma of the Hand: An Unusual Presentation in a Young Hispanic Male

Ewing's sarcoma is a neuroectodermal malignancy classically associated with innocuous and chronic symptomatology. Although tumors typically involve the axial skeleton, some malignancies may be confined to extraosseous tissue only. This report presents the case of a 15-year-old Hispanic male with a tender, slow-growing mass of seven months in the subcutaneous tissue of the right hand. Core needle biopsy and fine needle aspiration confirmed the diagnosis of high-grade extraosseous Ewing's sarcoma and the patient was treated via surgical resection and chemotherapy. Nonspecific findings of Ewing's sarcoma may mimic infection or trauma and contribute to a delay in diagnosis. However, social and economic influences including limited English proficiency and insurance status also critically affect the timing of presentation.
