Vitiligo: a good prognostic factor in melanoma?
Dermatology Online Journal
|April 2, 2009
Summary
Vitiligo, a skin condition, may indicate a delayed immune response to melanoma, suggesting a positive prognostic factor for patients undergoing treatment. This case highlights a potential link between vitiligo and improved melanoma outcomes.
Area of Science:
- Immunology
- Dermatology
- Oncology
Background:
- Vitiligo is often associated with a favorable prognosis in melanoma patients receiving immunotherapy.
- The precise immunopathogenesis linking vitiligo and melanoma remains unclear.
Observation:
- A 71-year-old woman with a history of malignant melanoma developed vitiligo-like macules two years after interferon treatment.
- Despite the vitiligo onset, the patient experienced long-term survival free of visceral metastases, with recurrences limited to the lower limb.
Findings:
- The appearance of vitiligo, even with a delay after treatment, may signify a delayed but effective immunological response against melanoma cells.
- This case supports the hypothesis that vitiligo can be a positive prognostic indicator in melanoma patients.
Implications:
- Further research into the immunopathogenesis of vitiligo in melanoma patients is warranted.
- Understanding this association could lead to improved therapeutic strategies and patient outcomes in melanoma treatment.

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

01:19Pigmentation
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
