There are several skin growths (lesions) that are very common and benign (non-cancerous) such as mole removal treatments, but individuals seek removal of them due to cosmetic reasons. Some may bleed and cause irritation, such as redness and discomfort, because of their location. We offer skin tag removal, mole removal treatment, and removal of other cosmetic skin growths. We utilize several techniques to remove the lesions depending on location, size, quantity and type of lesion. Type of lesions we remove include:


  • Lentigines (sunspots, age spots, freckles, or liver spots): flat, brown, usually small but sometimes large, spot that is associated with aging or sun-damaged skin that develop anywhere on the skin.


  • Acrochordon (skin tag): common, acquired, benign skin growths that are skin- or flesh-colored tissue and look like a small piece of soft, hanging skin. They are found on the neck, underarms, upper trunk, eyelids, groin folds, and under the breasts.

  • Seborrheic Keratoses (SK): greasy, waxy, flesh-colored to dark-colored, “stuck-on” lesion. They are common in elderly people; usually located on face, torso, shoulders or back.


  • Actinic Keratoses (AK) also known as solar or senile keratoses: rough, scaly, red papules or plaques that occur on sun exposed areas such as face, scalp, ears, neck, arms, hands, torso, and legs. They are typically seen in fair-skinned individuals with a history of chronic sun exposure. If untreated, these lesions may become skin cancer.


  • Nevi (moles): small fleshed to pigmented colored benign growths on the skin that come in various shapes, sizes, and colors. Moles can be round, oval, flat, or raised. Moles can appear anywhere on the skin, alone or in groups.


  • Dermatosis Papulosa Nigra (DPN): many small, smooth, raised, benign skin lesions on that face and neck that closely simulate seborrheic keratoses, a condition generally presenting on dark-skinned individuals. They never become malignant.


  • Phlebectases (Venous Lake): soft, compressible, dark blue to violaceous papule generally occur among the elderly and commonly found on sun-exposed surfaces of the vermilion border of the lip, face and ears.


  • Cherry angiomas (also known as capillary angioma, and capillary hemangioma): cherry-red to purple colored benign skin made up of clusters of dilated capillaries on the surface of the skin commonly found on the torso but can occur almost anywhere on the skin.


  • Telangiectasias: small dilated blood vessels near the surface of the skin found anywhere on the body but are commonly seen on the face around the nose, cheeks, and chin.


"I had some medium-sized cists that were growing on my head removed at Sima Medical & Cosmetic Clinic in Madison Park. Parl, Scar and Blood free!! Not to mention painless. Sima did a great job explaining to me how things were to proceed and the whole experience was very professional. I love the time and care shown by the staff and how you are not just ushered in and out. This is truly a cozy and cute little clinic. Now when I comb my hair I definitely don't have to worry about hitting a rough patch!"


"I went in as I was struggling with sever cystic acne. I saw Sima and she spent quite a long time explaining how my particular acne may have been caused by hormones. I left with a game plan and a few prescriptions. I had my follow-up with her 6 weeks later, and by then, my acne was under control. I started seeing her for laser hair removal (her prices are the best and she has cutting edge equipment). My 13 year old daughter developed acne and Sima created a custom game plan with her….she is now acne free!!!!  I will be scheduling my first annual mole check with Sima (did not even know about this important service that everyone should get). Love, love, love this place!!!

  • Pros: Superb Ambiance & Expert Medical Staff

  • Cons: can't think of a single one!!! "


"I have been to the Sima Medical & Cosmetic Clinic in Woodinville and it not only has a warm inviting feeling, but the people there make u feel very welcomed and make you want to go back again. Before being recommended to go this place I went to 2 doctors during the course of 3 weeks due to a some bumps on my arm which was very itchy. The doctor first diagnosed this as scabies. She put me on some medications to get rid of it, but it just got worse and worse and started spreading more. I was in much shock and went to another doctor to get another opinion and the other doctor said is was scabies too and gave me more meds for it. After 3 weeks of much irritation and itchiness I had to go back to the fist doctor for her to see how bad it was getting. She referred me to go to Sima's Clinic. I called in immediately and they were able to give me an appt the next day. I went in and Sima Rafii had seen me. She is soo awesome! She diagnosed the problem right away and it turned out to be eczema. She didn't even need to run any test on me or anything she was able to tell just by looking at it. She was able to put me on the right meds to get it treated right away. My arm has healed so well Thanks to Sima! She is soo great! I highly recommend anyone with any skin irritations to go see her, probably before even going to a doctor and spending all that money.Thanks again Sima for your help in making me feel better!"


"Sima is professional and thorough. I initially went to the Seattle location for a growth on my neck which had been previously "cryo'd" at a Kirkland Dermatologist's office. Someone had recommended Sima to me but when I called Kirkland they said she had moved to her own office and I decided Seattle was too far for me so I went to the Kirkland office. Disappointing to say the least. When the growth didn't go away I decided to find Sima and I saw her at her clinic. She removed and biopsied the growth which made me feel confident in my choice. The growth was successfully gone and benign."
