If you’ve ever woken up with odd, smooth and circular bumps plaguing different areas of your skin, it’s likely you may have fallen victim to molluscum, a common skin condition.

While this skin condition may not be too irritating, it is contagious and therefore, it’s important to understand exactly what molluscum is and how to treat it.

Here to answer some of the most common questions about molluscum is our very own Elizabeth Drumm, FNP-C, DCNP.

What is molluscum?


“Molluscum contagiosum (MC) is a very common viral skin infection. MC may appear in any age group, including adulthood, although it is most commonly seen in children.”


What does molluscum look like?


It presents as small, skin colored to pink, smooth bumps. Molluscum is typically not irritating or painful, although it may cause some itch. The lesions can grow larger over a few weeks. Due to a high risk for spreading the virus, the lesions may increase in number.



What causes molluscum?

“Molluscum is caused by a poxvirus that only affects humans.” 

You can contract this virus in a number of different ways. 

Using a towel that’s been infected with the virus can transfer is to you as well as skin-to-skin contact, using an infected razor, and coming into contact with the virus in any way.

Is molluscum contagious?

“Yes, molluscum is contagious and may pass to others by skin to skin contact or via touching contaminated clothing, towels, toys, and more. It may be spread to other areas on the body by scratching or picking at the lesions. It is also spread through sexual contact.”

Surrounding eczema or rash may accompany the molluscum. This may increase the risk of spreading due to the desire to scratch.

Avoid shaving if you have molluscum due to risk for transferring the virus along the route of the razor.

How is molluscum treated?

“Molluscum will resolve without treatment within months to years. Watchful waiting is a treatment option and may even be recommended depending on the location of the lesions and/or the age of the patient.”

However, due to the risk for spreading, there are treatment options for removal. 


Here are a few common treatments for molluscum:

  • Topical irritant agents: such as Retin-A (tretinoin) cream applied nightly. This may take a few weeks before seeing any improvement.
  • Destructive treatments: such as liquid nitrogen “freeze spray” and cantharidin (canthacur) “beetle juice” solution. These will cause blistering and sores, which may be painful, with a goal to destroy the lesion. Canthacur is well tolerated in children, as it does not cause any pain during the clinic visit, although will cause sores at home.
  • Removal of the lesions with scraping (curettage) during your clinic visit. This may be painful.

If you believe you have this common skin condition, book an appointment with your dermatologist to discuss treatment options!


Sunscreen is one of the best life-saving products you can use. However, knowing the differences between different types and how to choose one that’s best for you is the most important thing.

What is the difference between physical and chemical sunscreen?

Sunscreen prevents damage to the skin by absorbing, reflecting, and/or scattering ultraviolet (UV) radiation. There are a few key differences between physical and chemical sunscreen formulas.

Physical sunscreen (also referred to as mineral based sunscreen):

  • Active ingredients are minerals: zinc oxide, titanium dioxide
  • Sits on top of your skin and protects it by reflecting UV rays away from your body, providing a physical barrier between the sun’s rays and your skin
  • Typically less irritating than chemical sunscreens
  • Can be more difficult to blend into the skin than chemical sunscreens

Chemical sunscreens:

  • Active ingredients are chemical compounds: octinoxate, avobenzone, oxybenzone, homosalate, octisalate, octocrylene
  • Absorbs into the skin and absorbs the sun’s UV rays, which are then converted to heat and released from the body
  • Can cause skin irritation in those with sensitive skin
  • Typically absorbs more quickly into the skin than mineral-based sunscreens

How do I choose a sunscreen?

Finding the right sunscreen for you is super important because not all versions of sunscreen will react well with all skin types.

Here are my tips for how to choose a sunscreen:

  • Sunscreen should have broad-spectrum coverage, meaning protection against both UVA and UVB rays.
  • If you have oily or acne prone skin, I recommend using a non-comedogenic (meaning it won’t clog pores), oil-free sunscreen.
  • If you have sensitive skin, or for children and babies, I recommend using a physical/mineral based sunscreen containing only zinc oxide and/or titanium dioxide.
  • If you are swimming, playing sports, or sweating a lot during the day, it is important to use a water-resistant or waterproof formulation.


types of sunscreen

What SPF should I use?


SPF (sun protection factor) is a relative measure of how long a sunscreen will protect you from UVB rays.

The SPF factor works like this: whichever number SPF you get allows you to stay in the sun that amount of times longer without burning than you normally would. So if you normally burn after 30 minutes and use an SPF 15 sunscreen, you will be able to stay in the sun for 7.5 hours without burning (provided you used the product properly and reapplied when necessary).

I always recommend using a broad spectrum sunscreen, one that protects against both UVB and UVA rays, with at least SPF 30 or greater and to always follow your sunscreen’s application directions.

When should I apply sunscreen?


Sunscreen should be applied 15-30 minutes before sun exposure in order to provide optimal protection.

When outdoors, sunscreen should be reapplied every one to two hours (especially if swimming or sweating a lot). Remember to apply sunscreen to your ears and don’t forget to also apply a lip balm with SPF 30 or higher to protect your lips.

Do I really need to apply sunscreen every day?


Yes. I believe everyone should apply a daily moisturizer (or sunscreen) with at least SPF 30 to their face, neck, ears, and backs of the hands before heading outdoors.

Many people don’t realize that exposure to harmful ultraviolet radiation from the sun can occur even when it’s overcast and cloudy, while riding or driving in a car, or through windows. Temperature is unrelated to potential damage to your skin by UV rays, so be sure to apply daily sun protection year round, winter or summer.


Remember that sunscreen can only do so much. In general, try to avoid direct sun exposure between the hours of 10 AM and 4 PM, when the sun’s UV rays are the strongest.

Seek shade and wear sun protective clothing whenever possible and book regular skin-checks at your dermatologist!



It’s May! During this month we celebrate holidays such as Cinco De Mayo, Mother’s Day, and Memorial Day to name a few. It marks the end of the school year and is the official start of the summer season. . .

…but did you know that it is also Skin Cancer Awareness Month?

I can’t think of a better month to raise awareness about this preventable form of cancer than the month of May, especially since this is when many of us begin to spend more time outdoors.

The Skin Cancer Foundation reports that skin cancer is the most common form of cancer in the United States, with over five million new cases diagnosed each year. A vast majority of these cases can be linked directly from exposure to ultraviolet radiation (UV) from the sun.

My goal for this article is to help familiarize you with the common forms of skin cancer that are seen in our office and provide you tips on how to prevent them, as well as recognize early warning signs as a flag to take action and have them evaluated. . .

...sooner rather than later!

What causes skin cancer?

While there are a number of factors contributing to skin cancer, sun exposure is among the most common.

The sun emits two main forms of UV rays, UVA and UVB. Both of these types of rays are capable of penetrating the skin to cause permanent damage to the cells below.

UVA penetrates more deeply than UVB and can cause genetic damage as well as photo aging (a.k.a. wrinkles, discoloration, etc.) and immune-suppression.

UVB rays penetrate into the epidermis, the top layer of the skin, and are more responsible for sunburn, which places an individual at a greater risk for skin cancer, especially melanoma. UV rays can also contribute to eye damage.

Another important point to note is that we can also sustain exposure to UV rays from sources other than the sun, such as in tanning beds.

Over time, if the body cannot repair the damage sustained to the cells, they can begin to divide and grow in an uncontrolled way which may have the potential to eventually form a tumor. These tumors can be cancerous—and therefore, deadly.

The Most Common Forms of Skin Cancer

As I mentioned before, skin cancer can be preventable. Oftentimes, we can see pre-cancerous lesions on the skin in individuals who have had lots of UV exposure over time.

These lesions are called Actinic Keratoses (AKs) and are predominantly found on fair skinned individuals in sun-exposed areas such as the head, face, neck, and backs of the hands or forearms.

AKs concern us because they have the potential to evolve into a form of skin cancer known as squamous cell carcinoma (more on that one later).

What you are looking for here initially is a poorly defined area of redness with or without small visible blood vessels. Over time, these spots may evolve and develop a thin transparent, white, or yellow scale.

They can usually be felt by your fingertips and are often mistaken for dry skin. The hallmark is that they do not go away, even with moisturizers. If these lesions are not treated, eventually they may progress to forming a thicker scale and can become raised, and sometimes sore or painful.

It is estimated that 10% of untreated actinic keratoses progress to squamous cell carcinoma.

We recommend that if you notice any red, dry, scaly spots that are persistent or worsening over time to come in for an evaluation. We have many ways to treat these lesions and prevent them from transitioning into skin cancer.

The most common form of skin cancer is called Basal Cell Carcinoma (BCC). This cancer derives from the basal layer of keratinocytes, the predominant cell type of the epidermis (the top layer of the skin).

Basal Cell Carcinoma

Like AKs, basal cell carcinomais also more likely to be found in people with fair skin in sun-exposed areas. It is most common after age 40, however, it may appear at any age. The most common risk factor is cumulative sun exposure over time.

BCC has many variants, some more aggressive than others.

What does basal cell carcinoma look like?

Look for any flat or raised pink or translucent spots. These tumors grow slowly and enlarge over time, sometimes developing tiny superficial blood vessels or rolled raised borders.

BCCs may also bleed with minor trauma such as shaving or rubbing with a towel, but the warning sign is that it is a lesion that does not heal or go away.

Although these tumors rarely metastasize, they will enlarge and locally invade the surrounding skin if left untreated.

This can be very concerning if they are located on an eyelid, lip, nose or the ears. A biopsy is usually performed to confirm the diagnosis to determine the type of BCC that is present. We have many treatment options for BCC, however, the type, size, and location are taken into consideration when recommending treatment.

Squamous Cell Carcinoma

Squamous Cell Carcinoma (SCC) is the second most common form of skin cancer that we see. SCC is more invasive than BCC. It also arises from the keratinocytes of the skin and is most common in the sun-exposed areas of the body in elderly patients after years of cumulative UV exposure.

Caucasian people with fair skin are at the greatest risk.

Unlike BCC, which is primarily due to sun exposure, SCC can also be caused by other factors such as tobacco, chronic infections and inflammation, burns, and the human papillomavirus infection.

People who are immunocompromised are at an even greater risk. Our main concern with SCC is that if left untreated, it does have the potential to metastasize through the lymphatic system to the local lymph nodes and beyond.

What does squamous cell carcinoma look like?

These lesions are usually pink to a dull red color with firm, poorly defined raised bump with yellowish scale. As the lesions progress, they may become more raised with a crusted center. Skin biopsies are recommended for all suspected squamous cell carcinomas and as with BCC, the treatment needed may vary depending upon the type, size, and location of the tumor.

Malignant Melanoma

Our third most common skin cancer is Malignant Melanoma (MM). MM is a cancer of the melanocytes, the pigment-producing cells of the skin.

Of the three skin cancers described in this article, MM is the most serious.

It is potentially curable with early detection and treatment, however, if it is left untreated, may carry a poor prognosis.

The risk factors include having fair skin, the presence of atypical moles in both sun-exposed areas as well as sun-protected skin, a personal and/or family history of MM, a history of blistering sunburns, and a history of pigmented birthmarks (congenital nevi).

Earlier detection and treatment are the key to a more favorable prognosis as the cancer can grow rapidly and spread through the lymphatic system to other areas of the body. Normal moles do not have any symptoms, however, if a mole is sore, itchy, bleeds, or demonstrates any other symptoms, have it evaluated by a dermatology provider.

Other Criteria to look for would be to evaluate your moles for the ABCDEs of skin cancer:

A = Asymmetry. Check your moles to see if it is symmetrical; meaning that one half matches the other. If not, the mole is asymmetrical and should be evaluated.

B = Border Irregularity. Normal moles should have smooth, even border. A mole should be evaluated if the borders appear to be scalloped, jagged, or seem to fade out.

C = Color Variegation. Moles should demonstrate an even color scheme. If you see new colors, colors that are changing, or there are multiple colors it is time for a check.

D = Diameter > 6mm. If your mole is larger than the size of a pencil eraser, and/or growing, an evaluation is recommended.

E = Evolution. Monitor your moles with each monthly Self Skin Examination. If your moles appear to change or grow (evolve) over time, it is best to have them evaluated.

What does malignant melanoma look like?

MM can be tricky to diagnose. While they primarily arise from existing moles, this is not always the case. MMs are not always brown or black in color. A form of melanoma called Amelanotic Melanoma can simply appear as a colorless, pink or red spot.

They can be easy to miss, delaying their diagnosis which can potentially affect overall prognosis. For this reason, we highly recommend that you perform a monthly Self Skin Exam on yourself and have an annual evaluation with a dermatology provider, especially if you are over 40 years old.

Make sure to report any lesion that is new and changing or does not heal. The Skin Cancer Foundation has step by step instructions on how to perform this examination on yourself. For more information please visit SkinCancer.org.

Skin Cancer Prevention

The number one way to prevent skin cancer is to protect your skin. We recommend that during any season you apply a broad spectrum (UVA/UVB) sunscreen containing Zinc Oxide and/or Titanium dioxide of at least a sun protection factor (SPF) of 15-30 at least every two hours to any exposed areas when outside.

Be sure to use about one ounce of the product (about the amount in a shot glass) to ensure adequate coverage. It is also a good idea to use a facial moisturizer containing sunscreen to your face, ears, and neck daily before you leave the house.

In addition to sunscreen, sun protective clothing and hats can augment your prevention when outside. Look for garments containing an ultraviolet protection factor (UPF) of 30 or above.  Protect your eyes with UV blocking sunglasses. If you have a long commute or are in your car much of the day, consider having UV blocking films applied to your side car windows for added protection.

We recommend that year-round seek the shade when outside between the hours of 10AM and 4 PM. It is also advisable to avoid getting sunburned and never use UV tanning beds. Keep newborn children out of the sun and begin using sunscreens on babies after six months of age.

With these tips, you are well on your way to maintaining healthy skin. When it comes to skin cancer, earlier detection is the key to well-being. This May and beyond, stay safe by performing monthly self-skin exams and see your dermatology provider with any concerns and at least once a year for a full skin exam.
