Summary
This case report details a rare neck angiosarcoma originating from the internal jugular vein. The patient underwent successful surgical resection and radiotherapy with no recurrence observed.
Area of Science:
- Vascular oncology
- Surgical pathology
- Head and neck cancer
Background:
- Primary angiosarcoma is a rare malignancy with a typically poor prognosis.
- While commonly found in the head and neck, deep soft tissue neck involvement is exceptionally uncommon.
- This report focuses on a unique presentation of angiosarcoma within the neck's deep soft tissues.
Observation:
- A 79-year-old male presented with a rapidly enlarging right neck mass.
- Diagnostic imaging (CT, MRI, PET-CT) and fine-needle aspiration cytology indicated a malignant tumor of unknown origin.
- Immunohistochemical staining of the resected specimen confirmed angiosarcoma.
Findings:
- The tumor was identified as angiosarcoma arising from the right internal jugular vein.
- Immunostains for CD31, CD34, factor VIII-related antigen, and D2-40 were positive.
- The patient received postoperative radiotherapy (66Gy) to the right neck and upper mediastinum.
Implications:
- This is the first reported case of angiosarcoma originating from the internal jugular vein.
- The successful management highlights the importance of accurate diagnosis and multimodal treatment for rare neck malignancies.
- Further research into deep neck soft tissue angiosarcomas may improve understanding and treatment strategies.

7.5K
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

01:15Development of the Lymphatic System
2.8K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

01:24Esophageal Varices-I: Introduction
2.3K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...
