Spider naevus: A condition that needs immediate care and medical attention


Spider naevus or spider veins formation is a common medical phenomenon. It is a usually widespread condition appearing in different places all over the body. Spider veins on nose with Little’s area involvement, spider naevus on the abdomen in the periumbilical region, spider naevus on legs or the upper extremities are common appear. Spider veins or the spider naevus are also familiar as vascular telangiectasis or vascular spider angioma. Vascular stands for any event related to the blood vessels. It can be with either artery or vein. Spider naevus usually forms with arteries and arterioles. Venous relation with naevus is also not very uncommon. Angioma dictates as a tumor of the blood vessels. Spider naevus occurs most of the time with a central tumor-like lesion and spider-like vascular attachment. Here in this article, we will discuss the etiology or cause, Predisposing factors of spider naevus, risk factors of spider naevus, and the proper medical approach to treat the condition.

Etiology of spider naevus

The etiology or cause of a particular disease plays a significant role in detecting disease, a treatment plan. Spider naevus almost always collaborates with underlying liver disease. Liver cirrhosis is the most likely collaboration when spider naevus appears in the periumbilical region of the abdomen. The condition usually represents ascites and abdominal distension. Ascites are the accumulation of excess fluid in the stomach under or outside the peritoneal cavity. Some other diseases can also collaborate with spider naevus, like rheumatoid arthritis, rheumatic heart disease, thyrotoxicosis, etc. Other than the pathological causes, spider naevus can occur in some normal physiological conditions too. Pregnancy and malnutrition are the most common causes of spider naevus or spider angioma. Spider naevus is not a disease itself but a burning symptom of other underlying conditions like fever. So, if you see something similar to the spider naevus on your body or face, then immediately seek medical attention from your nearest general practitioner or hospital.


Spider naevus has a different presentation since it appears almost everywhere in the body with different etiology. As a standard and ideal spider, naevus will present with central erythema and connecting the vascular tract. The vessels radiate from the central and red erythema. The complete structure containing the center and the radiating vessels gives a spider’s impression, which is why the disease is after spider naevus. Spider naevus usually represents more than three separate lesions suggestive of Chronic underlying liver disease or other conditions. Less than three lesions are generally benign and not aggressive. Spider naevus is a painless lesion with a less aggravating nature—about three percent of people present with spider naevus in hospitals worldwide.

The epidemiological predisposition of spider naevus

There is no gender-related predisposition in spider naevus. So, it means males and females may get this disease in equal percentage at any age of life. But early age and teenagers have a better healing rate than adults or later extremities of age. Usually, the most prominent portion presenting spider naevus has chronic liver disease. Alcoholic liver disease is the most common among all the reasons for spider angioma or telangiectasis. Other than alcoholic liver disease, there is liver cirrhosis, congenital hepatomegaly, liver insufficiency. Increasing serum SGPT levels are also responsible for the condition. Pregnant women present with spider naevus almost all the time in the third trimester of pregnancy. It may dissolve after the delivery. But, sometimes, it takes years to resolve the issue altogether. Hormonal contraceptive pills are another most important causative agent of spider naevus. Once the patient stops taking hormonal pills, then the symptoms will go off.
