Overview
Common causes of merkel cell carcinoma include merkel cell polyomavirus, age, skin tone, exposure to sunlight and history of immunosuppression.
Cause
Merkel cell cancer is caused by Merkel cell polyomavirus (MCV) infection.[1]
Common Causes
Common causes of merkel cell carcinoma may include:[2]
- Merkel cell polyomavirus
- Especially MCPvy
- Sunlight
- Ultraviolet radiation especially UVB plays an important role in the developing merkel cell carcinoma
- Skin tone
- Fair skin people are more prone to merkel cell carcinoma
- Immunosuppression[3][4]
- Especially patients with HIV positive and organ transplant patients
Less Common Causes
Less common causes of merkel cell carcinoma include:
- Age
- The risk increases with the age and the median age is around 65 years or above
- Location in the body from decreasing order
- Head > Upper limb > Lower Limb > and Trunk
Genetic Causes
- Merkel cell carcinoma is caused most commonly by mutation in
- TP53 gene mutations
- Retinoblastoma (RB1) gene mutations
