What Are Uncommon Skin Cancers? Causes, Symptoms & Diagnosis
Skin cancer develops when abnormal cells in the skin grow uncontrollably. The most common types are basal cell carcinoma and squamous cell carcinoma.
Melanoma is a less common type of skin cancer. It begins in melanocytes, the cells that make melanin, the pigment that gives skin its colour. Melanoma is more likely than the more common skin cancers to spread to other parts of the body.
There are also rarer types of skin cancer. Merkel cell carcinoma is a very rare skin cancer that tends to grow quickly and can spread to other parts of the body. Less common forms of melanoma include acral melanoma, which can develop on the palms, soles of the feet or under the nails.
Symptoms vary depending on the type of skin cancer. Melanoma may appear as a new or changing mole or spot on the skin. Merkel cell carcinoma often appears as a fast-growing, painless, firm lump, usually on sun-exposed skin.
Diagnosis usually involves examining the affected area and taking a biopsy, where a small sample of tissue is removed and examined for cancer cells. Further tests may be needed to find out whether the cancer has spread and to help plan treatment.
Your Uncommon Skin Cancer Consultation: What to Expect
Every skin cancer diagnosis is different, so the focus and length of your consultation will depend on the specific cancer, its stage and your individual circumstances.
Generally, your specialist will discuss your medical history and diagnosis and review available pathology, imaging and previous treatment information. Depending on the diagnosis, further pathology review, molecular testing or imaging may be considered before treatment is planned.

Our Approach to Uncommon Skin Cancer Treatment
Treatment for melanoma and other uncommon skin cancers depends on the exact diagnosis, stage, location, pathology or molecular features, previous treatment, overall health and treatment goals.
Treatment may involve different specialties depending on the diagnosis and stage. Our medical oncologists work with other clinicians involved in a patient’s care to support diagnostic review and treatment planning.
Depending on the cancer, treatment may include surgery, radiation therapy, immunotherapy, targeted therapy, chemotherapy or a combination of approaches. For melanoma, treatment can differ according to stage and specific gene changes; for Merkel cell carcinoma, treatment may include surgery, radiation therapy and immunotherapy.
