Excision is used for moles, viral warts, epidermoid cysts, lipomas and atypical naevi, and also for melanoma and basal cell or squamous cell carcinoma. Many of these lesions are benign, but others have malignant potential, so medical assessment always comes before the decision.
Warning signs are a change in colour, irregular borders, rapid growth, bleeding and persistent itching. Excision is also indicated for constant rubbing, recurrent infection or for aesthetic reasons, and the diagnosis may be supported by dermoscopy and a prior biopsy.
The procedure is a day case, carried out under local anaesthetic, and takes about thirty minutes. The lesion is excised with an adequate safety margin and the closure is chosen according to size and depth: direct suture, skin graft or local flap. Where malignancy is suspected, oncological protocol is followed and the specimen is analysed.
Most patients return to their normal activity the same day and the sutures come out between five and ten days later. The final aesthetic result is seen at around six months, once the scar has matured.
Strict sun protection of the treated area is advised for a year. For suspicious or malignant lesions, follow-up does not end with surgery: a plan of regular dermatological reviews is put in place.
The skin is the largest organ in the human body, and also the most visible. Any change on its surface can affect a person’s health as much as their appearance. Against that background, removing a skin lesion becomes a medical procedure that, simple as it is to perform, calls for clinical judgement, technical precision and an aesthetic eye.
At the Instituto de Cirugía Plástica del Mediterráneo clinic in Valencia we specialise in skin lesion removal with the best possible outcome, in medical safety and in the quality of the scar alike.
Would you like to book a consultation to have your case assessed?
A skin lesion is any localised change in the skin, visible or palpable, that differs in shape, colour, texture or consistency from the healthy tissue around it. Some are present from birth, such as certain moles, while others appear over time because of sun exposure, viral infection, a build-up of fat under the skin or even a genetic predisposition.
The commonest skin lesions include:
Moles, or melanocytic naevi
Viral warts
Epidermoid cysts
Lipomas (collections of fat)
Atypical naevi
Melanoma
Basal cell and squamous cell carcinoma
Many of these lesions are benign, but others can have malignant potential. That is why the essential first step is always a specialist medical assessment.
When a skin lesion should be removed
Not every lesion needs surgery. There are, however, medical and aesthetic criteria that make removal advisable:
Signs of malignancy: changes in colour, irregular borders, rapid growth, bleeding or persistent itching are all warning signs.
Location in sensitive or sun-exposed areas: the face, neck, décolletage or backs of the hands.
Functional problems: constant rubbing, inflammation or recurrent infection.
Aesthetic reasons: where the lesion affects how the patient sees themselves.
In every case the decision rests on an accurate medical diagnosis, which may include dermoscopy and, where necessary, a prior biopsy.
What does the procedure involve?
Removing a skin lesion is a day-case procedure that usually takes about 30 minutes and is carried out under local anaesthetic. It requires no hospital stay and no complicated preparation. The general process follows these steps:
Clinical assessment beforehand: the surgeon examines the lesion, its extent, its depth and where it sits.
Surgical marking: the area to be treated is outlined precisely.
Local anaesthetic: anaesthetic is infiltrated into the area so that the procedure is painless.
Excision of the lesion: the lesion is removed with an adequate safety margin. Where malignancy is suspected, an oncological protocol is followed.
Reconstruction and closure: depending on size and depth, this may be direct closure with fine sutures, a skin graft or a local flap.
Review and aftercare: precise instructions are given to help the wound heal well.
At the Instituto de Cirugía Plástica del Mediterráneo clinic we use advanced suture techniques to keep tension on the skin to a minimum, with fine threads that are either quickly absorbed or removed early. This gives fine, barely visible scars, even in exposed areas.
The commonest lesions and how each is approached
Moles (melanocytic naevi): most are benign, but any showing suspicious change should be excised and examined histologically. On the face or in other visible areas the approach has to combine oncological safety with aesthetic precision.
Viral warts: caused by the human papillomavirus (HPV), they can be removed by scalpel, curettage or electrocautery when topical treatments fail. Excision is quick and highly effective for stubborn warts.
Epidermoid cysts: these are cavities under the skin filled with sebaceous material. Removal includes taking out the capsule completely, to avoid recurrence. They should not be partially emptied, as this raises the risk of inflammation or infection.
Lipomas: soft nodules of fatty tissue. Although benign, they can grow and become uncomfortable. Removing them requires a direct incision and careful dissection so that the appearance of the area is preserved.
Atypical naevi: these sit somewhere between an ordinary mole and a melanoma. They should be excised with an adequate margin and examined histologically, as some can progress to malignant forms.
Melanoma and carcinoma: these need more extensive surgery, with well-defined oncological margins. They are sometimes accompanied by imaging and multidisciplinary follow-up.
Recovery and aftercare
Recovery after a skin lesion is removed is generally quick. Most patients can go back to their normal activities the same day, although we advise avoiding direct sun on the treated area for at least a year.
Routine aftercare includes:
Gentle cleaning of the wound with saline
Applying antiseptics as advised
Strict sun protection of the treated area for 1 year
Removal of sutures (where there are any) between 5 and 10 days later, depending on the type of suture and the area
Massaging the scar with a specific cream after the first few weeks to improve its appearance
In more complex cases we may recommend silicone sheeting, pressure therapy or even aesthetic medicine treatments to refine the final result.
The final result is usually seen after 6 months, once healing has fully matured. For benign lesions, no follow-up beyond the aesthetic one is needed. For suspicious or malignant lesions, however, a plan of regular dermatological reviews is put in place.
A good result comes down to three things:
Early, accurate diagnosis
The right surgical technique
Proper aftercare by the patient at home
Our team in Valencia is highly specialised in approaching each type of lesion in the safest and most aesthetic way possible, which lets us offer surgical treatment tailored to the individual and in keeping with the body’s own harmony.
Why choose a plastic surgeon for this?
Many of these lesions can be treated in other medical settings, but a plastic surgeon brings something different: the ability to put appearance first without compromising medical safety. That matters particularly for lesions on the face, neck, décolletage or other visible areas.
A plastic surgery specialist is also experienced in reconstructive techniques, which makes it possible to deal with larger lesions, to use grafts or flaps where needed and to anticipate how the scar will behave in the long term.
Removing a skin lesion is not only a matter of health; it is also one of emotional well-being and appearance. At our clinic in Valencia we offer a complete, professional and human approach, adapted to each type of lesion and to each patient. If you have any doubt about a lesion on your skin, do not let it go. An early diagnosis can make the difference, not only to the treatment but to your quality of life.
Get in touch with our medical team and ask for an assessment, with no obligation. We are here to help, looking after your skin with precision, science and care.

How do I know whether a skin lesion needs looking at?
You cannot tell over the internet, and this page is not going to try. What can be said is what makes it necessary for a doctor to see it, without waiting:
a lesion that changes: in size, in shape, in colour or in how raised it is;
one that bleeds on its own, ulcerates or forms a scab that never quite heals;
one that itches or hurts persistently;
one that does not look like the rest of yours: if all your moles look alike and one is different, that is the one to show;
one that is new in adulthood and keeps growing.
None of those signs means it is something serious. They mean the decision is not yours or mine: it has to be examined, and with the lesion in front of us it is settled in a single consultation.
And the other way round: the fact that a lesion has looked the same for years and causes no trouble does not automatically make it harmless. If it worries you, show it to someone.
Is what is removed analysed?
ICPM’s policy is clear: it is analysed whenever there is the slightest suspicion of malignancy, and also whenever the patient asks for it. The only thing left unanalysed are entirely benign lesions, where there is no diagnostic doubt at all.
The analysis is a histopathological examination, carried out by a pathologist, and it is what turns a clinical impression into a diagnosis. That report is the only way of knowing for certain what the lesion was, and also of knowing whether it was removed completely.
Put another way: if you have doubts about a lesion, you can ask for it to be analysed even if it looks harmless to the naked eye. And it is worth asking, here or at any clinic, whether the analysis is included in the price.
Does it hurt? What anaesthetic is used?
Most skin lesion removals are done under local anaesthetic: only the area is numbed, you are awake and you walk out on your own. What you feel is the sting of the anaesthetic; after that, pressure but not pain.
Things are different when the lesion is large, when there are several, when it sits in an awkward place or when the defect has to be reconstructed with a flap or a graft: sedation may then be considered. That is decided at the assessment, not before.
Can it not be removed with a laser, avoiding the cut?
A lesion can be destroyed with a laser, with cold or with electrocoagulation, and for some clearly benign lesions that is a reasonable option. But there is a difference worth understanding before choosing, and it is not a cosmetic one:
What is destroyed cannot be analysed. There is no specimen to send to the pathologist. If that lesion turns out to be something that needed studying, the information is gone, and the area is altered as well, which makes assessing it later harder.
That is why ICPM’s policy is that a lesion with the slightest suspicion about it is excised and analysed, even if the scar is a little bigger. The convenience of a method without a cut does not make up for being left without a diagnosis.
What will the scar look like?
There is always a scar: removing a skin lesion means cutting and closing. What can be controlled is how it turns out, and three things matter there:
Where it is. The back, the shoulders and the chest heal less well because of the tension in the skin; the face heals better, although it is where a scar shows most.
How the incision is designed. Orientation matters: a scar that follows the natural lines of the skin or falls in a crease shows far less than one that cuts across them.
How much has to be removed, which is not always fully known until the analysis comes back.
And one part that is nobody’s choice: the way you heal. If you have a history of keloids or of scars that widen, say so beforehand, because it changes the planning. Aftercare is set out in our scar protocol after surgery, and the options if a scar does not settle well, in scar revision.
And if the analysis says it was malignant?
Then the report governs everything, and one of two things happens: either the lesion was removed completely and with a sufficient margin, or a second operation is needed to widen it. How much wider is not a fixed figure: it depends on the exact diagnosis, the thickness and the location, and it is set by oncological protocols, not by a website.
One note that explains something people sometimes find puzzling: those margins are neither permanent nor unanimous. A systematic review published in 2026 points out that six randomised trials comparing wide margins (3-5 cm) with narrow ones (1-2 cm) found no significant difference in local recurrence or survival, and that recommended margins have been narrowing over the years; trials under way will go on refining them. The authors themselves warn that most of the data are observational and that this does not prove that a smaller margin is equivalent. It is set out here to explain why your surgeon talks about protocols rather than a universal figure, not as a criterion for your case: that is set by whoever is managing your diagnosis.
Is it covered by the public health service or by insurance?
It depends on why it is being removed. A lesion excised for a medical reason — because it is suspicious, because it bleeds, because it becomes infected — is usually covered, both by the Spanish public system and by many private insurers. A lesion removed only because it bothers you cosmetically is not.
The dividing line is drawn by the clinical report, so this is a question to put to your provider with that report in front of you, rather than the other way round.
