title: Leiomyosarcoma of the iliac vein.
abstract: Leiomyosarcoma of the iliac vein is a very uncommon tumor. We report the case of a 55-year-old man with leiomyosarcoma of the left iliac vein. The patient had abdominal pain and hematuria. Abdominal ultrasound and computed tomography scanning demonstrated a well-defined mass in the left inguinal region, probably arising from the left iliac vein. Ultrasound-guided needle-core biopsy was consistent with a malignant growth. The patient was operated on, and a neoplastic multinodular mass attached to the posterolateral wall of the iliac vein was found. The tumor was resected en bloc, and venous reconstruction was undertaken using a saphenous vein segment. The postoperative course was uneventful, and the histologic study of the resected specimen was confirmed microscopically to be a leiomyosarcoma. No signs of recurrence or metastasis were present 29 months after complete surgical resection.
