[Malignant endothelial vascular tumor with distal embolization (author's transl)].

This case report describes a malignant endothelial vascular tumor originating in the superficial femoral artery with distal embolization and formation of metastases in bones and soft tissue of the foot and lower leg. Clinically the case was considered to be microembolism of the foot. Diagnosis was established by biopsy of a cutaneous necrotic lesion in the lateral foot region. The histologic picture of the cutaneous and subcutaneous metastases is similar to that of systemic proliferating angioendotheliomatosis.
