Focal infantile haemangioma (Q39326)

Infantile haemangioma is a common benign vascular neoplasm which develops in about 4% of infants. It appears within weeks of birth as a blanched, blushed, or telangiectatic area that then rapidly proliferates for several months before entering a prolonged process of involution lasting up to 12 years, leaving a residual variably prominent scar. A solitary focal tumour is seen in about 85% of cases. Over half of cases are located on the head and neck. Complications include bleeding, infection, ulceration and, in tumours situated close to the eye, amblyopia.
