- Diameter: Melanomas are usually larger than 6mm (about the size of a pencil eraser).
- Evolving: Any change in size, shape, color, or elevation over time.

Diagnostic Procedures

Biopsy

A definitive diagnosis of malignant melanoma is made through a biopsy, which involves:
- Excisional biopsy: The entire mole or lesion is removed for examination.
- Incisional biopsy: A portion of the lesion is removed if it is too large to excise completely.
- Punch biopsy: A circular tool is used to remove a small core of skin.

Histopathological Examination

The biopsy specimen is examined microscopically by a pathologist to confirm the presence of malignant melanoma cells. Key histological features include:
- Atypical melanocytes: Abnormal cells that indicate malignancy.
- Invasion: Assessment of how deeply the melanoma has penetrated the skin layers.
- Mitotic activity: The presence of actively dividing cells can indicate aggressive behavior.

Staging and Classification

Once diagnosed, staging is essential to determine the extent of the disease. The American Joint Committee on Cancer (AJCC) staging system is commonly used, which considers:
- Tumor thickness (Breslow depth): The depth of the melanoma in millimeters.
- Ulceration: Presence of ulceration on the tumor surface.
- Lymph node involvement: Whether cancer has spread to nearby lymph nodes.
- Distant metastasis: Assessment for spread to other parts of the body.

Malignant melanoma, particularly when classified under ICD-10 code C43.72, refers to melanoma located on the left lower limb, including the hip. This type of skin cancer requires a comprehensive treatment approach that may vary based on the stage of the disease, the patient's overall health, and specific characteristics of the tumor. Below is an overview of standard treatment approaches for this condition.

1. Surgical Treatment

Excision

The primary treatment for localized malignant melanoma is surgical excision. This involves removing the melanoma along with a margin of healthy skin to ensure complete removal of cancerous cells. The width of the margin typically depends on the thickness of the melanoma, as determined by the Breslow depth. For melanomas less than 1 mm thick, a margin of 1 cm is often sufficient, while thicker melanomas may require wider margins[1][4].

Sentinel Lymph Node Biopsy

If the melanoma is of a certain thickness or shows other high-risk features, a sentinel lymph node biopsy may be performed. This procedure helps determine if the cancer has spread to nearby lymph nodes, which is crucial for staging and treatment planning[2][4].

Lymphadenectomy

In cases where the sentinel lymph node is positive for cancer, a complete lymphadenectomy (removal of lymph nodes) may be indicated to prevent further spread of the disease[1].

2. Adjuvant Therapy

Immunotherapy

For patients with higher-risk melanoma, adjuvant immunotherapy may be recommended following surgery. Agents such as nivolumab (Opdivo) and pembrolizumab (Keytruda) are commonly used to enhance the immune system's ability to fight cancer cells. These treatments have shown significant efficacy in reducing recurrence rates in high-risk patients[3][4].

Targeted Therapy

If the melanoma has specific genetic mutations, such as BRAF mutations, targeted therapies like vemurafenib or dabrafenib may be utilized. These therapies specifically target the mutated pathways that drive melanoma growth, offering a more personalized treatment approach[3][4].

3. Radiation Therapy

While not a primary treatment for melanoma, radiation therapy may be used in certain situations, such as for palliative care to relieve symptoms or in cases where surgical margins are not clear. It can also be considered for patients with in-transit metastases or for those who are not surgical candidates[1][2].

4. Clinical Trials

Participation in clinical trials may also be an option for patients with malignant melanoma. These trials often explore new treatment modalities, including novel immunotherapies, combination therapies, and other innovative approaches that may not yet be widely available[3].

5. Follow-Up Care

Regular follow-up is crucial for melanoma patients, as early detection of recurrence can significantly impact outcomes. Follow-up typically includes physical examinations, imaging studies, and possibly blood tests to monitor for signs of recurrence or metastasis[2][4].

Conclusion

The treatment of malignant melanoma of the left lower limb, including the hip, is multifaceted and tailored to the individual patient. Surgical excision remains the cornerstone of treatment, supplemented by adjuvant therapies such as immunotherapy and targeted therapy for high-risk patients. Ongoing research and clinical trials continue to expand the options available, providing hope for improved outcomes in melanoma management. Regular follow-up is essential to ensure early detection of any recurrence, allowing for timely intervention.
