Terminology of vascular conditions can be confusing, with several lesions being incorrectly named or classified. Vascular skin lesions include:
A paediatric dermatologist, paediatrician, vascular specialist or surgeon should assess significant infantile capillary malformations or proliferative haemangiomas, especially when large, symptomatic (eg ulcerated), located on the head and neck or close to eye, nose or mouth.
Vascular naevi or anomalies are present at birth or appear in early childhood. They are classified according to the size and type of vessel. They may remain stable or become more prominent with maturity. There are various associated syndromes.
An angioma is a benign tumour formed by dilation of blood vessels or formation of new ones by proliferation of endothelial cells.
Bacillary angiomatosis is a rare opportunistic bacterial infection due to Rochalimaea henselae.
Prominent cutaneous blood vessels can be physiological or pathological.
There are some named conditions in which telangiectasia is (or telangiectases are) characteristic.
