Extramammary eczema-like carcinoma is mainly treated by surgical excision and postoperative chemotherapy. Patients who cannot undergo surgery can choose radiation therapy, and advanced patients can be given the best nutritional support therapy. Early stage of extramammary eczema-like carcinoma without dermal invasion is usually treated by simple surgery, which is usually localized wide excision, i.e., excision of normal skin 2.5cm from the lesion. Microsurgical tracing excision is currently preferred as the best treatment option. Surgical transverse excision, the range is for those with clear margins of the lesion, and the cutting edge is 1cm from the edge of the lesion of the normal skin, and surgical longitudinal excision ranges from the epidermis where the lesion is located to the removal of all epidermis, dermis, and subcutaneous tissues. Surgical treatment can be supplemented with local chemotherapeutic drugs, such as local topical fluorouracil ointment and intramuscular injection of pingyangmycin. Radiation therapy can be chosen to kill the tumor if the patient is older or combined with other more serious diseases, as well as inoperable patients and patients who experience recurrence after surgery. Patients with advanced disease may be treated with fluids and given optimal nutritional support. If extra-mammary eczema-like carcinoma is present, it should be seen promptly and treated under the guidance of a medical professional.
