Skin tags are a benign dermal disease very frequent in the general population. Their exeresis is indicated in case of discomfort of the affected person (usually because of friction or increase in size). In the minor surgery guidelines, their extraction is recommended with cryotherapy, electrocoagulation or shaving with cauterization of silver nitrate (traditional healing techniques). This randomized clinical trial proposes its extraction with a non before referenced technique in the manuals of minor surgery and that is nowadays applied with very good outcomes in the domain of pressure ulcers, chronic wounds and, in recent years, in acute wounds; the moist healing environment. Therefore, the investigators propose the surgical exeresis of the fibroid in the most proximal part of the pendulum with the subsequent placement of a thin hydrocolloid dressing. The objective of this trial is to compare the traditional healing with the moist healing environment in minor surgery, analyzing costs, time invested by the professional, healing time and their respective complications. Expected results: faster healing and lower cost are expected with the new technique. By contrast, more complications are expected in the techniques of cryotherapy and silver nitrate. Applicability / Relevance: it is a common pathology usually treated in the minor surgery office or routine visit. Therefore, it can show us which treatment leads to fewer complications for the patient and which is more cost-efficient for the health system.
Study variables: * Sex: Dichotomous qualitative variable: woman/man. Clinical history collection. * Age: Discrete quantitative variable in years from the date of birth included in the clinical history. * Family history. Dichotomous qualitative variable: yes/no. According to the interview with the participant, the family history of first and second degree skin tags will be considered. * Location of the lesion. Qualitative variable categorized in 6 items: Trunk/ armpit/ neck/ inguinal/ upper extremity/ lower extremity. * Diabetes Dichotomous qualitative variable: yes/no. According to conditioning factors and problems in the clinical history and interview with the participant. There are studies that relate insulin resistance with the presence or not of skin tags 37, 38. To be able to study if the results obtained are independent of the variable of suffering from DM. * Cost: Continuous quantitative variable, expressed in euros. The cost will include the performance of the technique in the first minor surgery visit, the post-surgical cures and the follow-up visits. The standardized cost of each of the interventions has been calculated according to the different techniques for approaching skin tag, from the prices published in DOGC 6326 of 1 March 2013 Resolution SLT/353/2013 of 13 February on the review of public price corresponding to the health services provided by the Institut Català de la Salut. Apart from the price for the minor surgery visit of the different approaches, the price of the follow-up visits has been calculated in case of prolonged healing time of the lesion or the appearance of complications (infection or non-viable tissue...). * Healing time: Discrete quantitative variable expressed in days. It will be considered 'healing' when the lesion has concluded the phases of inflammation and granulation/epithelialization. It will be the moment when it does not require any cure and lacks non-viable tissue (the days in the remodeling phase in which the participant uses skin care such as moisturizing, sun protection... will not be counted). For the monitoring of this variable, in the follow-up visits, the state of scarring will be evaluated and if it is already healed, it will be asked on what day prior to the visit, the lesion did not need any special cure and lacked non-viable tissue. * Time invested by the professional: Discrete quantitative variable expressed in minutes. The time invested in each visit will be recorded until it is healed. * Complications: Infection: Dichotomous qualitative variable: yes/no. Infection is considered when the wound shows inflammation signs of infection. * Devitalized tissue: Dichotomous qualitative variable: yes/no. The appearance of slough will be observed. * Technique: Qualitative variable categorized in 4 items: * Dry Cure - Electrocoagulation. * Dry Cure - Cryotherapy. * Dry Cure - Silver Nitrate. * Cure in a moist healing environment.

The patient will be prepared before this technique by removing all metal objects in his possession. The area should be disinfected with a local antiseptic, leaving the area aseptic. Afterwards, perilesional infiltrated local anaesthesia (subcutaneous or intradermal) will be applied. Once the area has been anaesthetised, excision is made with scissors cutting through the most proximal part of the skin tag pendulum and the lesion is coagulated with the handle or knife of the electrocoagulator (previously regulated with the intensity in coagulation mode). The resulting abrasion will form an eschar that will be disinfected with povidone-iodine, and a protective dressing of sterile occlusive gauze bandage will be placed. Indications to the patient: the project participant will be instructed to dry the area with povidone-iodine antiseptic and not to expose the area to extreme humidity or sunlight.
The patient should be prepared: the area should be disinfected with a local antiseptic, leaving the area aseptic. for a few minutes the tip of an Adson forceps will be introduced in a container with liquid nitrogen until freezing. It will then be applied to the most proximal part of the skin tag pendulum until it is observed that the frostbite has reached the base of the lesion and the surface becomes whitish, with a halo of 1-3 mm. When this happens, it will be excise above the frost part in the pendulum. After application, it is disinfected with povidone- iodine and covered with a protective dressing of sterile occlusive gauze plaster. It will then form an eschar. Indications to the patient: the project participant will be instructed to dry the area with povidone-iodine antiseptic and not to expose the area to extreme humidity or sunlight.
The patient should be prepared: the area should be disinfected with a local antiseptic, leaving the area aseptic. Excision will be made with scissors of the skin tag cutting through the most proximal part of the skin tag pendulum, then cauterized with the tip of the silver nitrate rod, trying not to apply in the perilesional zone. The resulting abrasion will form an eschar that will be disinfected with povidone-iodine, and a protective dressing of sterile occlusive gauze bandage will be placed. Indications to the patient: the project participant will be instructed to dry the area with povidone-iodine antiseptic and not to expose the area to extreme humidity or solar rays.
The patient should be prepared: the area should be disinfected with a local antiseptic, leaving the area aseptic. Excision will be made with scissors of the skin tag by cutting through the most proximal part of the pendulum of the skin tag, later it will be disinfected with chlorhexidine and thin hydrocolloid dressing will be placed. Indications to the patient: the project participant will be told not to touch the dressing until the next control after 3 days with the research team. In case of incidents with the dressing (fall of the dressing), the patient will be given a replacement dressing for this purpose and be able to restore it immediately. It is recommended not to expose the area to the solar rays

Healing time
Discrete quantitative variable expressed in days. It will be considered 'healing' when the lesion has concluded the phases of inflammation and granulation/epithelialization. It will be the moment when it does not require any cure and lacks non-viable tissue (the days in the remodeling phase in which the participant uses skin care such as moisturizing, sun protection... will not be counted). For the monitoring of this variable, in the follow-up visits, the state of scarring will be evaluated and if it is already healed, it will be asked on what day prior to the visit, the lesion did not need any special cure and lacked non-viable tissue.
