Mole Check

A “mole check” is one of the most common reasons to visit a dermatologist. Dermatologists are trained to examine and diagnose moles which look suspicious for cancers or other skin cancer.

Our dermatologist, Dr. Liew, was trained in various prestigious dermatology departments in the United Kingdom, including King’s College Hospital and Chelsea and Westminster Hospital in London. Therefore, Dr Liew possesses the experience and knowledge in diagnosing and managing skin cancers.

At your first visit, our dermatologist will conduct an assessment of your risk of developing abnormal moles or skin cancer.

Following this, a full skin examination is performed and for this you are required to undress to your undergarment. If you are concerned with any growths or moles in your genital or scalp, please inform our dermatologist.

We assess moles with specialized hand-held light devices, known as dermoscope to analyse your moles. If required, a digital dermatoscopic record of your mole can be recorded for future reference.

We also offer mole mapping if you have multiple, unusual looking moles or have a high risk of developing skin cancers. This is a specialised technique to capture digital photos of your moles while mapping your moles with the dermatoscope, which require close monitoring. These photos will be uploaded onto our electronic medical record for future reference. You can also request a copy of the mole map or photographs.

Mole mapping will benefit those with:

— Many moles (more than 50 to 100)
— Atypical or dysplastic nevi – moles that are large or of unusual color(s) or shapes
— Moles on the back, which may be difficult to keep an eye on
— Previous history of melanoma
— Strong family history of melanoma
— Moles and fair skin that have been severely sunburned
— Concerns about individual moles or freckles, eg, because of their appearance or recent change

If you think you need a mole mapping service or skin surgery, please inform our clinic staff at +65 6254 6646 so that we can allocate more time for your visit.

We may be able to provide this one stop mole check and treatment on the same day, unless you need to obtain approval from your insurance before we can proceed with the treatment if necessary.

Mole Removal

What is Mole Removal?

Mole(s) removal is a medical procedure that can be performed either via laser, cauterization +/- shave excision or surgical excision. Moles are usually removed if there is a suspicion of skin cancer, however it can be removed for cosmetic reason.

Removal via laser

This modality is only recommended for small flat moles, if there is no suspicion for skin cancer. Laser mole removal eliminates unwanted moles without damaging the surrounding skin cells. However, some of these pigmented skin cells may remain beneath the skin after laser and therefore there is a small risk of recurrence. Generally, laser mole removal is less likely to form scars as compared with other methods of mole removal. The treatment is minimally invasive and tends to heal well, with minimal downtime. Laser mole removal is ideal for cosmetic reason, in particularly on the face.

Removal via cauterisation

Cauterisation is the medical technique of using heat to burn off tissue. It is another popular method used for mole removal. A specialized cauterization tool will be used to apply heat to the surface of the mole, causing it to vaporise. For larger and protruding moles, shaving of the mole followed by cauterisation. However, some of these pigmented skin cells may remain beneath the skin after cauterisation and therefore there is a small risk of recurrence.

Surgical Excision

Surgical excision is the gold standard treatment for removing all types of moles, in particular, for moles that have changed and there is a strong suspicion for skin cancers. Local anesthetic is used to numb the area so any discomfort is minimised. With this method, the mole is cut out with a scalpel, along with a small amount of skin surrounding the area to ensure more of the pigment cells are removed entirely. Cutting out these moles usually require a few stitches, resulting in a small scar, which will improve with time. The excised mole will be sent away for histological analysis and the results will be discussed with you in clinic.

Obstetric Dermatology

Skin changes during pregnancy or just after pregnancy is not uncommon. The common physiological skin changes are stretchmarks, melasma (pigmentation on the face), hair & nail changes, and increased blood vessel – related skin growths, example pyogenic granuloma and spider naevi.

However there are other skin conditions which are specific to pregnancy, for example, atopic eruption of pregnancy (similar to eczema but these women may not have any history of skin allergies previously), pruritic urticarial papules and plaques of pregnancy (also known as PUPPP), and intrahepatic cholestasis of pregnancy, and pemphigoid gestationis.

Fortunately, the last 2 mentioned skin conditions are rare but can be severe and may impact your unborn babies. You may already have an existing skin condition, which can be exacerbated by your pregnancy, for example acne, rosacea, psoriasis, etc.

Our dermatologist Dr Liew, who was a consultant in KK Women’s and Children’s Hospital in Singapore has the knowledge and expertise in looking after pregnant women with skin conditions. She will assess your skin condition and arrange the necessary tests and discuss the best treatment options that are safe for you and your baby.

Psoriasis is a chronic skin condition, presenting with thick, inflamed and flaky skin. It is not contagious.

Psoriasis could occur on any part of the skin, usually the elbows, knees and back, sometimes affecting the nails, scalp and joints.

In Singapore, psoriasis is one of the top ten most commonly treated skin diseases, affecting 1-2% of the population. Itching is often experienced in our hot and humid climate.

Our dermatologist, Dr Liew, will go through your medical history and examine your skin condition thoroughly before she discusses with you or your caregivers on the right treatment for your psoriasis. We want to help you improve your quality of life.

Treatments we offer:

1. Topical management and nursing care
2. Oral immunosuppressant and monitoring
3. Biologics and monitoring

For mild psoriasis – Topical treatment with steroid and Vitamin D analogue will help to reduce the inflammation, thickness and the scales of the psoriatic rash.

For moderate to severe cases – Phototherapy, oral immunosuppressants or biologics can be considered. Research development in discovering various targeted immunological pathways in psoriasis have allowed development of many new biologics with good safety profile. In addition, majority of these biologics can help to improve psoriatic arthritis.

Dr. Liew has experience in initiating and monitoring immunosuppressants and biologic treatments.

What is Psoriasis? 

When psoriatic skin is exposed to triggers, your overactive immune system sends out signals that cause inflammation in the body and speed up the growth cycle of skin cells. Instead of weeks, your skin cell cycle renews within days. Rapid growth of skin cells makes it difficult for the cells to be shed quickly enough.

Newly produced cells move to the outermost layer of the skin rapidly, finally building up at the skin surface as thick, scaly psoriatic patches. This causes psoriasis lesions, which are abnormal changes to the skin in the form of plaques, pustules or areas of redness and swelling.

Psoriasis may present differently in each person. It can develop slowly with mild symptoms or quickly with severe symptoms. It can occur on any part of the body.

Types of Psoriasis: 

Plaque psoriasis

Most common type of psoriasis. It causes dry red patches and silvery scales to your skin. These plaques can appear anywhere on your skin, but most often appear on your elbows, knees, scalp, and lower back. They can be painful, and sometimes crack and bleed.

Guttate psoriasis

Common among children. It usually causes small pink spots, which commonly develop on the torso, arms, and legs. The spots caused by guttate psoriasis are rarely thick or raised like plaque psoriasis.

Pustular psoriasis

Characterised by pustules sometimes surrounded by reddened skin. Pustules are relatively large blisters of non-infectious pus, which consists of white blood cells. They are neither an infection nor contagious. Pustular psoriasis can appear on any part of your body, commonly on the hands and feet.

Inverse psoriasis

Characterised by smooth patches of red and inflamed skin which tend to worsen with sweating or friction. Inverse psoriasis affects areas of skin folds such as the underarms, under breasts, genital area and buttocks. Sometimes, fungal infection can trigger this type of psoriasis.

Erythrodermic psoriasis

Rare but aggressive form of psoriasis. Erythrodermic psoriasis can cause intense redness and shedding of skin that nearly cover the whole body. In most cases, it is accompanied by intense pain, itching, inability to maintain proper body temperature, and a fast heartbeat. You should seek medical advice immediately if you think you are having an erythrodermic flare.

Nail Psoriasis

Many patients who have psoriasis also see see signs of the disease on their nails. Symptoms could include dents in your nails (nail pits), discolouration, thickened nails or nail lifting from its nail bed.

Psoriatic arthritis

5-15% of psoriasis patients develop arthritis (pain and swelling of the joints), commonly referred to as psoriatic arthritis. This condition causes inflammation and progressive damage to your joints, which could result in permanent deformities of the joints. Timely treatment is important in preventing worsening of condition.


Rosacea is a common chronic inflammatory skin condition, predominantly on the cheeks and nose among the middle aged person. It is usually mistaken for acne.

There are 2 components to rosacea: the inflamed bumps and the background of prominent red blood vessels. Therefore, patient will usually need 2 forms of treatments: medical and procedural.

Our dermatologist will be able to diagnose this condition and guide you on the right treatment.

Medical treatments available:

Topical gels, Oral antibiotics, and various suitable treatment methods depending on your condition

Procedural treatments available:

1. Pulsed dye laser

Skin Allergy

Contact dermatitis is a kind of eczema that occurs when the skin comes into contact with a substance that you are allergic to.

The reaction is usually delayed and chronic. This is different from food allergy.

Contact dermatitis reaction is usually triggered by preservatives found in cosmeceutical products, fragrances, metals, clothing dyes, hair dyes, etc.

Our dermatologist, Dr Liew, will explore whether there is a possible trigger and will recommend patch testing to be done. Patch test to the common allergens as well as your own products can be arranged.

You will be required to visit our clinic 3 times in a week.

Skin Cancers

According to Skin Cancer Foundation Statistics, 1 in every 3 cancers diagnosed is a skin cancer. Fortunately, not all abnormal skin growths or moles are cancerous.

They could be pre-cancerous skin conditions such as dysplastic naevi, actinic keratosis, Bowen’s disease, or lentigo maligna, which has a small potential risk of transforming into skin cancers. Hence early detection and management of such pre-cancerous skin conditions is crucial in preventing skin cancers.

Fair skinned individuals who live in Singapore’s tropical climate are also at risk of developing skin cancers. Regular skin checks with a dermatologist is recommended.

Main types of skin cancer:

— Basal cell carcinoma (most common)
— Squamous cell carcinoma
— Melanoma

FAQs with Dr. Liew

FAQs with Dr. Liew

If your cyst is tender and inflamed, it is advisable to take a course of oral antibiotics first before going for surgery to remove it, in order to shrink the cyst and hence smaller scar.

Occasionally steroid injection can help to shrink the inflamed cyst. However, if the cyst is large and extremely painful, it is advisable to have it removed under local anaesthesia or even general anaesthesia in our clinic or hospital theatre.

FAQs with Dr. Liew

FAQs with Dr. Liew

Generally a flat mole (known as junctional naevus) can be treated easily with electrocautery or ablative laser such as CO2 laser. The reason being the pigment cells are on the superficial layer of the skin.

For a raised mole, whether with brown pigment or not, it is recommended for them to be removed surgically as the pigment cells are deeply seated. This procedure is called skin excision, which can be done under local anaesthesia. Another method for removing a protruding mole is shave excision, where only the top layer of the mole is removed.

Ultimately, the choice of mole removal method depends on your preference and cost.
