Neck mass due to thrombosis of the jugular vein in patients with cancer.

The hypothesis that jugular thrombosis (JT) may cause a mass in the cervical region is usually overlooked. The objective of the present study was to identify the characteristics of neck masses resulting from JT in cancer patients and to analyze the possible reasons for their formation. A retrospective study was conducted on 8 patients with JT affected by 3 types of neoplasia, ie, carcinomas (3 cases), adenocarcinomas (3 cases), and lymphomas (2 cases) located in the breast, digestive apparatus, lymphatic system (2 cases each), lung and an undetermined site (1 case each), diagnosed over the last 12 years.
