Distal metastases are classically situated below the knee or elbow. However, metastases of the extremities: wrist and hand, or ankle and foot, have etiological and histological characteristics. We report one case of bone metastasis and one case of soft tissue metastasis. The distal bone metastases are often solitary. Bronchial cancers represent the most frequent cause of distal metastases (20% of all cases). They are responsible for 50% of distal metastases of the upper limb and more often occurs as a squamous cancer. Their localization may sometimes reveal a bronchial cancer, and so allow curative surgery. The metastases of soft tissue are exceptional. In the literature, only 2 cases of soft tissue metastasis of bronchopulmonary cancer are described. Clinically, it is a painful swelling preserving the under lying bone. The prognosis is always one of bronchial metastasis cancer with an average survival of 3-6 months.
远处转移瘤通常位于膝部或肘部以下。然而，四肢（腕部和手部或踝部和足部）的转移瘤具有病因学和组织学特征。我们报告1例骨转移瘤和1例软组织转移瘤。远端骨转移瘤常为单发。支气管癌是远端转移瘤最常见的病因（占所有病例的20%）。它们导致上肢远端转移瘤的50%，且更常表现为鳞状癌。其定位有时可提示支气管癌，从而可行根治性手术。软组织转移瘤较为罕见。文献中仅描述了2例支气管肺癌软组织转移病例。临床上，表现为疼痛性肿胀，不累及下方骨骼。预后总是支气管转移癌的预后，平均生存期为3至6个月。
