Gynecologic mucosal melanoma is a rare, aggressive melanoma that forms in mucous membranes of the female reproductive tract — most often the vulva or vagina, and less commonly the cervix — and it differs from skin melanoma because it is not thought to be caused by UV exposure. Symptoms can resemble more common gynecologic conditions, which can delay diagnosis. MRA’s RARE Registry is helping researchers better understand symptoms, diagnosis patterns, and patient experiences to improve awareness and care in this area.
September is Gynecologic Cancer Awareness Month, an opportunity to increase awareness of cancers affecting the female reproductive system and encourage people to understand their bodies, recognize potential symptoms, and seek appropriate medical care.
It is also an opportunity to shine a light on a rare cancer many people may not associate with gynecologic health at all: mucosal melanoma.
Most people think of melanoma as a form of skin cancer associated with ultraviolet radiation exposure, such as from the sun. While this describes the vast majority of melanomas, melanoma can also develop from melanocytes found in mucous membranes, the moist linings found inside the human body.
This cancer is known as mucosal melanoma. It is a rare and aggressive form of melanoma that accounts for 1% to 2% of all melanoma cases. Mucosal melanoma is not believed to be caused by exposure to ultraviolet radiation. It also has different biological characteristics from other melanomas and is often diagnosed at more advanced stages. Mucosal melanoma can occur in several locations, including the mouth, sinuses, gastrointestinal tract, urinary tract, and genital areas. In women, mucosal melanoma can arise in the vulva and vagina, and less often in the cervix. Recognizing mucosal melanoma during Gynecologic Cancer Awareness Month is an important step toward closing gaps in women’s health.
Gynecologic mucosal melanoma is exceptionally rare. This rarity can create challenges for patients and physicians alike.
Symptoms can overlap with those caused by much more common and benign gynecologic conditions. Depending on the location of the tumor, changes may also be difficult for a person to see.
Possible symptoms of gynecologic mucosal melanoma can include a new or changing lump or mass, changes in pigmentation, persistent itching or pain, unexplained bleeding or discharge, or other persistent changes.
Any symptoms that are new, unusual, and persistent should be discussed with a healthcare professional.
Because individual physicians and medical centers may see very few patients with gynecological mucosal melanoma, bringing patient experiences and data together is critical for advancing our understanding of this rare disease and how it affects patients.
The Melanoma Research Alliance created the RARE Registry to help advance research on rare melanoma subtypes like mucosal melanoma. Through this direct-to-patient registry, patients share their experiences with melanoma through surveys based on disease and treatment history, genetic and tumor biomarkers, risk factors, lifestyle, and quality of life, among others. Data shared by participants can help researchers better understand how these cancers develop and progress, are diagnosed and treated, and impact on quality of life.
Since launching in October 2022, over 700 participants have joined the registry, including more than 270 with mucosal melanoma. Of these, 30% of participants reported having mucosal melanoma of the vagina, vulva, or cervix.
Here are some initial findings about gynecological mucosal melanoma:
For a cancer this rare, every patient experience can help build knowledge that benefits the patients who come next. To learn more about the RARE Registry, visit raremelanoma.org and read the 2026 RARE Registry Data Report.
MRA is committed to advancing research across melanoma—including rare subtypes like mucosal melanoma for which patients historically have had few to no treatment options and less research dedicated specifically to their disease.
That means bringing researchers together and developing resources that can accelerate discovery and innovative science that is dedicated to rare melanoma subtypes.
Gynecologic Cancer Awareness Month provides an important opportunity to broaden the conversation of rare melanoma subtypes like mucosal melanoma.
For a small but important group of patients, their cancer may be rare, but rarity should never mean fewer answers or fewer treatment options.
