Spider angioma in children
It is more common among children but it may appear on adults, too.
A spider angioma is an enlarged little artery, which resembles the body of a spider, from which smaller blood vessels are filled, which resemble the spider’s legs.
The cause of spider angiomas is not known. The vast majority affect healthy people, and most only have one spider angioma or a just a few. Despite the fact that spider angiomas can develop at any age, they are more common among children.
Spider angiomas are not hereditary. Diagnosis is based on their characteristic appearance. Apart from their appearance on the skin, spider angiomas are usually not related to other symptoms. In rare cases bleeding may occur if the spider angioma is picked or scratched.

Other vascular tumours
Kasabach – Merritt syndrome
It occurs in infants around the second month of life (at 7 weeks) and it is a rapidly growing vascular lump.
This is a rare benign tumour, which appears during infancy or early childhood, usually by the end of the first year of life. It usually occurs on the neck or upper torso as a red spot, which develops into a darker in colour nodule or plate, and its size increases slowly over time.
This is a rare tumour that occurs in babies and young children. It may appear as a multi-nodular mass of soft tissue, as a red spot or as multiple telangiectatic papules.
Angeiokeratomas are hyperkeratotic, asymptomatic, erythematous vascular type lesions and there are several different types of angiokeratomas. Some of the angiokeratomas that may occur in infants and children are briefly discussed below.
Angiokeratoma circumscriptum is a rare lesion present at birth. It appears as a hyperkeratotic vascular plaque of blue or black colour, and usually it occurs on the legs.
Angiokeratoma Mibelli occurs in children and young adolescents between the ages of 10 and 14 years. Initially it is bright sigmoidal red spots. It is an inherited in an autosomal pattern and usually there is a history of chilblains, although environmental influences have not been ruled out completely.
Solitary papular angiokeratoma is a wart-like, asymptomatic papule, which usually occurs on the legs and it has dark blue to black colour. Children may have this condition from the age of 10 years, but it may also occur in adults up to the age of 40 years old, while it is usually caused by an injury.
