Summary
Ewing's sarcoma in the thumb is rare. This case report details a successful treatment via disarticulation, with the patient remaining cancer-free for five years.
Area of Science:
- Orthopedic Oncology
- Skeletal Tumors
- Soft Tissue Sarcomas
Background:
- Ewing sarcoma is a rare bone cancer primarily affecting children and young adults.
- Distal phalanx tumors are uncommon, presenting unique diagnostic and surgical challenges.
- Extraskeletal extension can complicate treatment and prognosis.
Observation:
- A 51-year-old male presented with Ewing sarcoma involving the distal phalanx of the right thumb.
- A significant extraskeletal mass was associated with the primary bone tumor.
- Histopathological examination confirmed a round cell sarcoma with O13 monoclonal antibody reactivity.
Findings:
- The patient underwent disarticulation at the metacarpophalangeal joint.
- Post-operative follow-up revealed no evidence of recurrence or metastasis.
- The patient remained disease-free five years after the surgical intervention.
Implications:
- This case highlights the possibility of successful management of rare distal phalanx Ewing sarcoma.
- Early diagnosis and aggressive surgical treatment, such as disarticulation, can lead to favorable outcomes.
- Further research into multimodal treatment strategies for localized, rare sarcoma presentations is warranted.
