Angiogenesis is the formation of blood vessels. Oral KS has a variety of clinical presentations. The palate is the most commonly affected area but the gingiva and other oral sites can also be involved. Lesions are represented by red or purple macules, papules, or nodules, isolated or occurring in different sites simultaneously. Biopsy is the indicated diagnostic procedure.
Lesions are generally asymptomatic.
However,, nodular lesions can become bulky, ulcerated, and infected, interfering with patient's quality of life, and therefore requiring treatment. First of all, surgery means taking out the cancer. A doctor may remove the cancer using one of the following methods. Local excision cuts out the lesion and some of the tissue around it. Electrodesiccation and curettage burns the lesion and removes it with a sharp instrument.
