Core Viewpoint - A recent incident involving a girl from Chongqing who shared a photo on social media led to a diagnosis of a vascular tumor after a netizen pointed out a potential health issue, highlighting the importance of early detection and awareness of vascular tumors [3][5]. Summary by Relevant Sections What is a Vascular Tumor? - Vascular tumors, also known as vascular malformations, are common benign vascular lesions that are often present at birth and progress with growth and development. They can be categorized into capillary hemangiomas, cavernous hemangiomas, and arteriovenous malformations. Most vascular tumors are benign and can be controlled if detected early [5]. Warning Signs and Symptoms - Although most vascular tumors are benign, their severity can vary based on type, size, and location. Warning signs include: - Unexplained red or purple skin spots or elastic lumps under the skin, especially in common areas like the head, neck, and limbs [6]. - Persistent pain or burning sensations in the area of the tumor, which may worsen with activity or pressure [7]. - Numbness or movement difficulties in limbs due to nerve compression from the tumor [7]. - Sudden growth of the tumor, particularly if it increases more than 2 centimeters in a short time, necessitating immediate medical attention [8]. Detection and Diagnosis - Some superficial vascular tumors can be visually identified, but ultrasound (B-mode) is the preferred method for diagnosis. Ultrasound can detect deeper tumors that may compress organs, such as those in the liver, which can lead to complications like jaundice [11][13]. Care and Management - Proper care for diagnosed vascular tumors includes: - Maintaining cleanliness of the affected skin area to prevent bacterial growth [14]. - Protecting the skin from sun exposure with sunscreen and physical barriers [15]. - Eating a diet rich in fruits and vegetables to boost immunity and skin health, particularly those high in vitamins C and E [16]. - Ensuring adequate rest and managing stress levels [17].
