Understanding Merkel Cell Skin Cancer: ‘A lovely man gone way too soon’

On Friday, we mourned the loss of the iconic musician, Jimmy Buffett, who battled Merkel cell skin cancer for four years before passing away.

Remarkably, Buffett continued to perform throughout his cancer treatment journey. His final appearance was a surprise 45-minute performance at a Mac McAnally show in Portsmouth, Rhode Island, on July 2. The crowd erupted with excitement as he graced the stage, a testament to his enduring spirit. However, in 2022, he faced visible health challenges related to an undisclosed issue, leading to hospitalization and the unfortunate cancellation of several shows.

A statement announcing his passing conveyed that the 76-year-old musician found peace at his home in Sag Harbor on Long Island, New York, surrounded by the comforting presence of his family, friends, music, and beloved dogs.

The recent passing of legendary musician Jimmy Buffett due to Merkel cell skin cancer has brought attention to this rare and often misunderstood condition. Merkel cell carcinoma is a form of skin cancer that, while uncommon, can be aggressive and life-threatening. In this article, we will explore what Merkel cell skin cancer is, its risk factors, symptoms, and prevention strategies.

What is Merkel Cell Skin Cancer?

Merkel cell skin cancer is a rare carcinoma characterized by the uncontrolled growth of Merkel cells, which are found in the top layer of the skin and are associated with touch sensation. This type of cancer usually starts in areas of the skin that are exposed to the sun, such as the head, neck, arms, legs, and trunk. It has the tendency to metastasize early, spreading to lymph nodes and other parts of the body, including the lungs, brain, bones, and organs.

Risk Factors for Merkel Cell Skin Cancer

Several factors increase the risk of developing Merkel cell carcinoma:

  1. Age: It is more common in individuals over 50 years old, though it can affect people of all ages.
  2. Gender: Men are at a higher risk than women.
  3. Race: It is more prevalent in White individuals.
  4. Sun Exposure: Extensive exposure to natural sunlight, artificial sunlight from tanning beds, or PUVA therapy for psoriasis can elevate the risk.
  5. Weakened Immune System: Conditions that weaken the immune system and a history of other cancers can increase susceptibility.

Symptoms of Merkel Cell Skin Cancer

The appearance of Merkel cell carcinoma is distinctive:

  • It typically manifests as a rapidly growing, painless lump on sun-exposed skin.
  • The lump is firm, dome-shaped, and may be red or violet in color.
  • Most often, it occurs on the face, head, or neck but can develop anywhere on the body.

It’s crucial to consult a healthcare professional if you notice any changing moles, freckles, or skin abnormalities, especially if they grow rapidly or bleed easily.

Causes of Merkel Cell Skin Cancer

While sun exposure is considered a risk factor, recent research has shown that a common virus called Merkel cell polyomavirus plays a significant role in causing most Merkel cell carcinoma cases. This virus is ubiquitous and typically resides on the skin without causing symptoms. The exact mechanisms through which the virus leads to cancer are still being investigated, as other factors are likely involved.

Preventing Skin Cancer

Taking steps to prevent skin cancer, including Merkel cell carcinoma, is essential:

  1. Sun Protection: Avoid direct sun exposure during peak hours (typically 10 a.m. to 4 p.m.), and wear protective clothing, hats, and sunglasses.
  2. Sunscreen: Apply broad-spectrum sunscreen with an SPF of at least 30, even on cloudy days. Reapply every two hours and more frequently if swimming or sweating.
  3. Skin Monitoring: Regularly check your skin for any changes in moles, freckles, or skin growths.
  4. Consult a Dermatologist: If you notice any suspicious skin changes, consult a dermatologist for a professional evaluation.

Jimmy Buffett’s battle with Merkel cell skin cancer serves as a reminder of the importance of skin cancer awareness and prevention. By staying vigilant, protecting yourself from excessive sun exposure, and seeking prompt medical attention for any concerning skin changes, you can reduce your risk and increase the likelihood of early detection and successful treatment of skin cancer.


Merkel cell skin cancer, though rare, can be a serious and aggressive condition. Understanding its risk factors, symptoms, and prevention measures is crucial for individuals of all ages and backgrounds. By taking proactive steps to protect your skin and seeking medical attention for any suspicious changes, you can contribute to the early detection and management of this condition, potentially saving lives in the process.
