Scaphoid metastasis as the first sign of occult gastroesophageal junction cancer: A case report.

BACKGROUND: Metastatic tumors of the hand are very rare. They are usually late manifestations of massive advanced malignancies. However, a small portion of acrometastases are indications of occult primary cancer. Here, we report an extremely rare case in which a scaphoid bone lesion was the initial manifestation and was found to be a metastasis from gastroesophageal junction (GEJ) cancer. CASE
SUMMARY: A 57-year-old male patient presented with ongoing left wrist pain and swelling after trauma. He was initially misdiagnosed with infection of the scaphoid bone and treated with antibiotics and anti-inflammatory drugs. Further radiographic investigations showed a scaphoid pathological fracture, indicating a metastatic tumor derived from the GEJ and/or right lung malignancies. Gastroscopy failed to identify the pathology of the mass at the GEJ, which grew in an exophytic pattern. A lung puncture biopsy was not performed because the patient refused the procedure. To relieve his wrist pain and obtain a definite pathology, we resected the scaphoid lesion. Based on the clinical and pathological results, the patient was finally diagnosed with multiple metastases of advanced GEJ adenocarcinoma. He underwent chemotherapy and died 6 mo after his initial presentation.
CONCLUSION: Despite the rareness of the disease, orthopedic surgeons should consider the possibility of metastasis to the bones of the hand when patients complain of persistent and progressive pain in the hand. ©The Author(s) 2020. Published by Baishideng Publishing Group Inc. All rights reserved.
