Cervical Melanoma: A Rare and Aggressive Form of Cancer

Cervical melanoma, also known as primary malignant melanoma of the cervix, is a rare and aggressive form of cancer that originates from the melanocytes in the cervical region. It is considered an extremely rare disease, accounting for only 3% to 9% of all mucosal melanomas [8].

Clinical Manifestations

The main clinical manifestations of cervical melanoma include:

• Vaginal bleeding and vaginal discharge
• Unusual vaginal bleeding and post-coital bleeding (in most patients) [3]
• Bleeding between periods or after menopause
• Pain during sex
• A blood-stained or smelly vaginal discharge

Prognosis

Unfortunately, cervical melanoma has a poor prognosis. The 5-year overall survival (OS) rate for patients with this cancer is approximately 10%, and many patients die within three years of diagnosis [11]. The main prognostic factor for cervical melanoma is the FIGO stage at the time of diagnosis.

Treatment

Most cervical malignant melanomas are found in the early stage, but regardless of stage, most patients were treated by surgery. If combined with adjuvant therapy, chemotherapy was the main treatment, followed by radiotherapy, with fewer treatments involving immunotherapy [15].

Early Warning Signs and Symptoms of Cervical Melanoma

Cervical melanoma, a rare type of cancer that affects the cervix, can be challenging to diagnose in its early stages. However, there are some warning signs and symptoms that may indicate the presence of this condition.

• Unusual vaginal bleeding: This is one of the most common symptoms of cervical melanoma, especially in advanced cases (1). Vaginal bleeding after intercourse, between periods, or after menopause can be a sign of cervical cancer (2).
• Vaginal discharge: A bloody or foul-smelling vaginal discharge can also be a symptom of cervical melanoma (3). This type of discharge may be heavy and persistent.
• Pelvic pain: Some women with cervical melanoma may experience pelvic pain, which can range from mild to severe (4).
• Enlarged lymph nodes: In some cases, cervical melanoma can cause the lymph nodes in the neck or groin area to become enlarged (5).

It's essential to note that these symptoms can also be caused by other conditions, such as infections or benign growths. Therefore, if you experience any of these symptoms, it's crucial to consult a healthcare professional for proper evaluation and diagnosis.

Diagnostic Tests for Cervical Melanoma

Cervical melanoma, also known as skin cancer on the cervix, requires a thorough diagnostic process to confirm the presence and extent of the disease. The following tests are commonly used to diagnose cervical melanoma:

• Skin biopsy: A biopsy is a procedure where a sample of tissue from the affected area is taken for examination under a microscope. This test can help determine if the growth is cancerous or not.
• Lymph node biopsy: If the biopsy shows that the cancer has spread to the lymph nodes, a lymph node biopsy may be performed to confirm this.
• Cell and tissue studies: These tests examine cells and tissues from the affected area to identify any abnormal cell growth.
• Imaging tests: Imaging tests such as CT scans, MRI, chest X-rays, and PET scans can help determine if the cancer has spread to other parts of the body.

Additional Tests

If an abnormal area on the skin might be cervical melanoma, your doctor may recommend additional tests to confirm the diagnosis. These may include:

• Chest X-rays: To check for any metastasis (spread) of the cancer to the lungs.
• PET scan: To determine if the cancer has spread to other parts of the body.

Importance of Accurate Diagnosis

Accurate diagnosis is crucial in determining the best course of treatment for cervical melanoma. A correct diagnosis can help doctors choose the most effective treatment plan, increasing the likelihood that the treatment will be successful [1][2].

Treatment Options for Cervical Melanoma

Cervical melanoma, also known as primary cervical melanoma, is a rare and aggressive form of skin cancer that occurs on the cervix. While it's not as common as other types of melanoma, treatment options are available to help manage the disease.

• Dacarbazine: This chemotherapy medication is often used to treat advanced-stage or recurrent cervical melanoma. According to search result [2], about 15%–20% of patients respond to this treatment.
• Pembrolizumab: This immunotherapy medication has been shown to be effective in treating certain types of melanoma, including cervical melanoma. Search result [4] mentions that pembrolizumab injection is used alone or in combination with other chemotherapy medications to treat certain types of melanoma.

Other Treatment Options

While not specifically approved for cervical melanoma, targeted therapy and immunotherapy may also be considered as treatment options. Targeted therapy involves identifying and attacking specific cell features, such as BRAF gene mutations [5]. Immunotherapy works by blocking the PD-1 pathway to help prevent cancer cells from hiding [8].

Key Takeaways

• Dacarbazine is a commonly used chemotherapy medication for treating advanced-stage or recurrent cervical melanoma.
• Pembrolizumab has shown promise in treating certain types of melanoma, including cervical melanoma.
• Targeted therapy and immunotherapy may also be considered as treatment options.

Differential Diagnoses for Cervical Melanoma

Cervical melanoma, a rare and aggressive form of cancer, requires a comprehensive differential diagnosis to ensure accurate identification and treatment. The following conditions should be considered in the differential diagnosis of cervical melanoma:

• High-grade squamous intraepithelial lesion: A precancerous condition that can progress to invasive cancer if left untreated [1].
• Atypical glandular cells: Abnormal cell growth that may indicate a higher risk of developing cancer [2].
• Adenocarcinoma: A type of cancer that originates in the glandular tissue, which can be found in the cervix [3].
• Poorly differentiated malignancies: Cancers with unclear or ambiguous characteristics, which can make diagnosis challenging [4].

Key Considerations

When diagnosing cervical melanoma, it is essential to rule out secondary metastasis from other sites, such as skin and eye melanomas. A thorough examination of the patient's medical history, physical symptoms, and laboratory results is crucial in making an accurate diagnosis.

Diagnostic Criteria

The following criteria are used to diagnose primary cervical malignant melanoma:

1. Absence of melanoma elsewhere in the body: No evidence of melanoma in other parts of the body [5].
2. Presence of junctional change in the ectocervix: Abnormal cell growth at the junction between the ectocervix and the endocervix [6].
3. Presence of melanin pigment in the normal cervical epithelium: Melanin pigmentation in the normal cervical tissue, which can indicate primary origin of melanoma [7].
4. Metastasis according to the pattern of cervical carcinoma: Metastatic spread consistent with cervical cancer [8].

Prognosis and Treatment

Cervical malignant melanoma is a particularly aggressive form of cancer with a poor long-term prognosis. Early detection and treatment are critical in improving patient outcomes.
