Ewing's sarcoma of the finger: report of two cases and literature review

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.

An Extraosseous Ewing Sarcoma of the Index Finger Masquerading as a Benign Tumor

Ewing sarcoma is a malignant, small, round, blue cell tumor that often affects the long bones and pelvis. It is rarely seen in the bones of the hand. A minority of Ewing sarcoma cases arise in soft tissue. This case report details the clinical and radiological presentation of an extraosseous Ewing sarcoma of the index finger in a 22-year-old woman. Treatment consisted of an index ray amputation followed by adjuvant chemotherapy. After 1 year, the left hand had excellent function with an acceptable cosmetic appearance and no evidence of metastasis or local recurrence.

Ewing's Sarcoma of the Finger

Ewing's sarcoma is a mesenchymal cell tumor usually seen in long bones but very rarely seen in the bones of a finger. Swelling and pain are the most common complaints of the affected finger. In radiological imaging, it may be seen as permeative bone destruction accompanied by a soft tissue component or an expansile bone lesion. A 27-year-old right-hand dominant female patient presented with a swelling on the proximal phalanx of her right 3^rd finger that had existed for 3 years. However, the mass started to gradually increase in size and the pain worsened over a period of 5 weeks. The mass was excised under regional intravenous anesthesia and Ewing's sarcoma was confirmed following a histopathological evaluation. No local recurrence or metastasis was detected 1 year after surgery. Since Ewing's sarcoma is rarely seen in the finger, we present this case with its radiological and clinical findings.

Ewing sarcoma of the first metacarpal with a 9-year follow-up: case report

Ewing sarcoma is a primary bone tumor that rarely occurs in the hand. We present a case involving the thumb metacarpal with long-term follow-up. Carpometacarpal and metacarpophalangeal arthrodeses with autograft are relatively simple procedures that stabilized the thumb and preserved satisfactory function.
