What is Merkel Cell Skin Cancer? Symptoms and Signs of the Rare Disease

We must pay attention to the uncommon and dangerous skin cancer known as Merkel Cell Carcinoma (MCC). Knowing the signs and symptoms of this skin cancer is essential for early discovery and successful treatment, even though it may not be as well-known as some other skin cancers. We will go into the topic of Merkel cell skin cancer in this post, explaining what it is and how to spot it.

What is skin cancer with Merkel Cells?

MCC, also known as Merkel cell carcinoma, is a rare form of skin cancer. Merkel cell carcinoma poses different difficulties than other types of skin cancer, such as melanoma, basal cell carcinoma, or squamous cell carcinoma.

Merkel cell carcinoma warning signs and symptoms:

Its appearance can be deceiving because Merkel cell carcinoma (MCC) is an uncommon skin cancer that frequently seems unthreatening. It might be mistaken for a number of common skin conditions, including an insect bite, sore, cyst, stye, or pimple. Understanding its symptoms and indicators is essential for early detection because of this.

Merkel cell cancer often manifests as a hard, painless cutaneous nodule. The following are a few warning signs and symptoms to look out for:


The presence of a solid nodule is the most distinguishing hallmark of MCC. In its early stages, it might be mistakenly diagnosed as a number of benign skin disorders.

Rapid Growth: 

The MCC-related nodule usually develops swiftly. A skin lesion should be taken seriously if its size changes suddenly and noticeably.

Texture :

The nodule’s surface texture, which may be distinct from the skin around it, maybe shiny or smooth.


MCC nodules can be any color, although they frequently have a red, purple, or flesh tone to them. It might be difficult to differentiate from other skin abnormalities because of the variety in coloring.

Ulceration and Bleeding: 

The nodule may occasionally bleed or experience surface ulceration. Due to the fact that benign skin disorders typically do not display these symptoms, this can be a very worrying warning.

Several less well-known signs of skin cancer should not be disregarded, even if many people are aware of the common indications, such as modifications to moles or the formation of strange growths. For early detection and quick medical intervention, being aware of these symptoms can be essential. Here are seven skin cancer warning signals you may not be aware of:

Brown Spots That Have Changed or Are New: 

Not all cases of skin cancer exhibit the classic brownish mole. Watch out for spots that appear suddenly, change color, or have wavy edges as these could be signs of skin cancer.

Skin Changes in Unexpected Locations: 

Skin cancer can appear in unanticipated places, such as the palms, soles of the feet, or beneath the nails. Watch out for any odd alterations or growths in these less frequent areas.

A Lesion That Bleeds: 

If a lesion or patch on your skin starts bleeding suddenly, it’s a warning sign that you shouldn’t ignore. A skin cancer early warning symptom can even be slight bleeding.

A Painful Lesion: 

Skin cancer can sometimes cause painful lesions. Some skin malignancies can be uncomfortable or painful, which is sometimes written off as a minor problem. A medical checkup is necessary if a skin lesion is causing persistent pain.

A Lesion That Itches: 

A skin lesion that itches continuously in one area of your body may be a non-obvious indicator of skin cancer. Consult a healthcare provider if an area itches and over-the-counter treatments are ineffective.

A Spot with a Crater-Like Appearance: 

 Merkel cell carcinoma is one type of skin cancer that can occasionally leave a “crater” or depression in the skin. This trait is often confused with other skin disorders.

quick Growth of a Spot: 

Pay close attention to any spots that experience quick growth. Sudden changes in size should raise suspicions because skin malignancies sometimes grow at accelerated rates.

It’s important to keep in mind that treating skin cancer successfully depends on early detection. Make an appointment with a dermatologist or other healthcare professional right away if you have any of these strange symptoms or are worried about changes in your skin. Self-examinations and expert screenings of your skin should be done frequently to maintain your skin’s health.

What Causes Skin Cancer with Merkel Cells?

To stop this uncommon but dangerous kind of skin cancer, it is crucial to comprehend the underlying causes of Merkel cell carcinoma (MCC). MCC shares a high correlation with ultraviolet (UV) radiation exposure, much like other forms of skin cancer like melanoma, basal cell carcinoma, or squamous cell carcinoma.

Sunlight Exposure:

Exposure to UV radiation, which can come from both natural and man-made sources, is the main recognized cause of Merkel cell cancer. Here is how UV radiation contributes to the growth of MCC:

Sun Exposure: 

Prolonged sun exposure poses a serious risk for developing MCC. Sunlight’s UV rays can alter skin cells’ DNA, which might result in mutations that could eventually lead to the growth of malignant cells.

 tanning beds:

Sun lamps and tanning beds are two more UV radiation artificial sources that should be avoided. Repeated exposure to the UV rays emitted by these devices can raise the chance of developing MCC and other skin cancers.

While UV radiation is a recognized risk factor for MCC, it’s crucial to remember that not everyone who has a history of sun exposure or tanning bed use will get this skin cancer. A poor immune system and genetic factors, among others, may potentially contribute to Merkel cell cancer development.

Treatment for Merkel Cell Carcinoma:

 The method used to treat Merkel cell carcinoma (MCC) depends on several variables, such as the cancer’s stage and the patient’s general condition. Because MCC is notorious for being aggressive, early identification and rapid therapy are crucial. Here are a few treatments for Merkel cell carcinoma that are frequently employed:


The first-line treatment for MCC in its early stages is frequently surgical excision of the tumor. To achieve thorough eradication, the surgeon strives to remove the malignant tissue together with a margin of healthy tissue. If nearby lymph nodes are damaged, they could also need to be removed in some circumstances.

Radiation therapy: 

To target any leftover cancer cells, radiation therapy may be applied either before or after surgery. Patients who are unable to have surgery for a variety of reasons may potentially consider it as an option.


When Merkel cell carcinoma has progressed to other parts of the body, immunotherapy has shown promise as a treatment. Checkpoint inhibitors are an example of an immunotherapy medicine that helps the body’s immune system identify and kill cancer cells.


Chemotherapy uses medications to destroy cancer cells. Depending on the particular medications and the treatment plan, it can either be given intravenously or as pills. When surgery and radiation therapy are ineffective or the cancer has spread far, chemotherapy may be performed.

Targeted Therapy: 

Drugs used in targeted therapy are made to block specific chemicals or signaling pathways that contribute to the development of cancer cells. They can be taken into account in some Merkel cell carcinoma cases, especially when the malignancy contains distinct genetic abnormalities.

Clinical Trials:

 Enrolling in clinical trials may provide you access to innovative, still-beta cures and treatments. When conventional treatments fail to work, people frequently investigate this alternative.

Recognizing potential symptoms and risk factors for Merkel cell carcinoma (MCC) requires an understanding of the key areas where the disease typically develops. This disease, MCC typically starts in parts of the skin that are exposed to sunlight. The following are typical sites where Merkel cell carcinoma begins:

Head and Neck:

 Merkel cell carcinoma frequently develops in the head and neck area, which includes the face, ears, scalp, and neck. Long-term exposure to the sun in these regions can encourage the growth of malignant cells.


MCC can also begin with the arms, particularly the forearms. Arm skin that has been exposed to the sun is more vulnerable to UV radiation, which raises the risk of skin cancer.


If the arms, the legs, especially the lower legs, are prone to Merkel cell carcinoma, particularly due to excess exposure to a lot of sunlight.


MCC can manifest on the trunk, which encompasses the chest and belly, although it is less prevalent. Skin cancer in these places can also be influenced by sun exposure to the torso.

Is there a treatment for Merkel cell cancer?

Yes, Merkel cell carcinoma (MCC) is curable, particularly if caught early. Early diagnosis and adequate treatment can significantly increase the likelihood of favorable outcomes. As covered earlier in the article, possible forms of treatment for MCC include surgery, radiation therapy, immunotherapy, chemotherapy, targeted therapy, and enrollment in clinical trials.

Early discovery is the key to successful treatment, so it’s critical for people to be aware of the symptoms and signs of MCC and to seek immediate medical attention if they see any alarming skin changes. To detect Merkel cell carcinoma early, healthcare providers should perform routine skin checks and screenings.
