Merkel cell carcinoma

Overview

Merkel cell carcinoma is a rare and aggressive type of skin cancer that typically affects older adults. It is also known as neuroendocrine carcinoma of the skin. The disease is characterized by the development of a flesh-colored or bluish-red nodule on the skin, often on the face, head, or neck.

Types of Merkel cell carcinoma

There are several types of Merkel cell carcinoma, including:

1. Primary Merkel cell carcinoma: This is the most common type of the disease and occurs when cancer cells develop in the Merkel cells, which are specialized skin cells that are responsible for sensing touch and pressure.
2. Secondary Merkel cell carcinoma: This type of the disease occurs when cancer cells spread from another part of the body to the skin.
3. Metastatic Merkel cell carcinoma: This type of the disease occurs when cancer cells spread from the skin to other parts of the body.

Causes of Merkel cell carcinoma

The exact cause of Merkel cell carcinoma is not known, but several factors may contribute to its development. These include:

1. Long-term sun exposure: Exposure to ultraviolet (UV) radiation from the sun or tanning beds can increase the risk of developing Merkel cell carcinoma.
2. Weak immune system: People with a weakened immune system may be more susceptible to developing Merkel cell carcinoma.
3. Genetic mutations: Certain genetic mutations may increase the risk of developing Merkel cell carcinoma.
4. Viral infections: Certain viral infections, such as Merkel cell polyomavirus, may also contribute to the development of Merkel cell carcinoma.

Risk Factors of Merkel cell carcinoma

Several factors may increase the risk of developing Merkel cell carcinoma, including:

1. Age: The risk of developing Merkel cell carcinoma increases with age, with most cases occurring in people over 60 years old.
2. Sex: Men are more likely to develop Merkel cell carcinoma than women.
3. Skin type: People with fair skin are more likely to develop Merkel cell carcinoma than those with darker skin.
4. Family history: A family history of skin cancer may increase the risk of developing Merkel cell carcinoma.
5. Weakened immune system: People with a weakened immune system may be more susceptible to developing Merkel cell carcinoma.

Preventions of Merkel cell carcinoma

Preventing Merkel cell carcinoma involves taking steps to reduce the risk factors associated with its development. These include:

1. Avoiding long-term sun exposure.
2. Wearing protective clothing and applying sunscreen.
3. Avoiding tanning beds.
4. Maintaining a healthy immune system.
5. Getting regular check-ups and screenings.

Diagnosis of Merkel cell carcinoma

Diagnosing Merkel cell carcinoma typically involves a combination of physical examination, medical imaging tests, and biopsies. The following tests may be used to diagnose and evaluate the disease:

1. Physical examination: A thorough examination of the skin and surrounding tissue may be performed to check for signs of cancer.
2. Medical imaging tests: Tests such as X-rays, CT scans, or MRI scans may be used to visualize the affected area and rule out other conditions.
3. Biopsies: A biopsy may be performed to remove tissue samples from the affected area for further examination.

Treatment for Merkel cell carcinoma

Treatment options for Merkel cell carcinoma typically depend on whether the cancer has spread beyond the skin. The following treatments may be used to manage the disease:

1. Surgery: Surgery may be used to remove tumors and surrounding tissue.
2. Radiation therapy: Radiation therapy may be used to kill cancer cells.
3. Chemotherapy: Chemotherapy may be used to kill cancer cells.
4. Targeted therapy: Targeted therapy may be used to specifically target cancer cells.

When to seek medical attention ?

If you are experiencing symptoms of Merkel cell carcinoma, it is important to see a doctor for further evaluation and treatment.
