Electrodesiccation and curettage (ED&C) is frequently used in the treatment of SCC, particularly for in situ or minimally invasive lesions on the trunk or limbs. The tumour is prepared for ED&C and margins are marked. Taking advantage of the finding that skin tumours are usually more friable than the surrounding normal tissue, the sharp tip of a curette is used to debulk the tumour. Electric current through a fine-tipped needle is used to desiccate the base and destroy any residual tumour. This sequence is repeated several times and the eschar that remains is left to heal by secondary intention.
