Removal of atheromas or lipomas is a minimally invasive procedure. Small-sized cysts or lipomas may be excised under local anesthesia on an outpatient basis. After the small wound has been secured with stitches and a dressing, the patient can go home. In very rare cases, it is necessary to use general anesthesia (large dimensions and difficult localization of the lesion, multiple lesions). After waking up from general anesthesia, the patient must remain in the hospital for at least one day for observation.
