Skin Cancer - Melanoma

Melanoma arises from pigment-producing melanocytes and can develop on any skin surface, including areas not heavily sun-exposed.

It tends to invade deeper skin layers and metastasize earlier than most non-melanoma skin cancers, so early recognition and staging are essential.

Treatment is stage-dependent and may include wide local excision, sentinel node assessment, targeted therapy or immunotherapy for advanced disease, and long-term surveillance.

Overview And Clinical Background

Biology, risk factors and clinical importance

Melanoma is biologically distinct from basal or squamous cell cancers and is driven by mutations (eg. BRAF, NRAS) in many cases.

UV exposure, intermittent sunburns, fair skin, family history, and numerous or atypical moles increase risk, while genetic testing and dermoscopic screening aid early detection.

Cell of originMelanocytes — pigment-producing cells in the epidermis — transform and gain the ability to invade local tissue and enter lymphatic or blood vessels, leading to metastasis if unchecked; molecular profiling often identifies actionable mutations.

Risk profileIntense intermittent UV exposure, history of sunburns, numerous or changing moles, immunosuppression, and family history raise melanoma risk and warrant proactive surveillance.

Clinical impactBecause melanoma can metastasize at an early stage, staging and sentinel node assessment directly influence prognosis and the choice of adjuvant systemic therapies.

Symptoms, Signs And Presentation

Melanoma commonly appears as a new or changing pigmented lesion; the ABCDE rule (Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolution) helps clinical recognition.

Early lesions may be subtle, and any rapidly changing spot or lesion that itches, bleeds or ulcerates should prompt urgent dermatologic evaluation.

Typical appearanceA mole or pigmented patch that is asymmetric, has irregular borders, multiple colors, or is enlarging over weeks to months — these features suggest malignant transformation and need biopsy.

Local symptomsItching, tenderness, bleeding, or surface breakdown can occur as the lesion progresses and are red flags for deeper invasion or secondary infection.

Advanced signsPalpable regional lymph nodes, non-healing ulceration, or systemic symptoms such as weight loss and persistent fatigue may indicate regional or distant spread and require rapid staging.

Diagnosis Methods And Investigations

Dermoscopy, biopsy and molecular testing

Diagnosis relies on clinical inspection with dermoscopy followed by an excisional or incisional biopsy for histopathology.

Staging uses sentinel lymph node biopsy for appropriate lesions and cross-sectional imaging (CT, PET-CT or MRI) when metastatic disease is suspected.

BiopsyComplete excisional biopsy with narrow margins (or deep incisional biopsy if excision not feasible) yields definitive histology, Breslow thickness measurement and mitotic rate which guide staging and management.

Sentinel node assessmentSentinel lymph node biopsy for intermediate- to high-risk melanomas identifies occult nodal disease and refines prognosis and need for adjuvant therapy.

Molecular profilingTesting for mutations such as BRAF, NRAS and KIT informs eligibility for targeted agents and clinical trials, particularly in advanced or recurrent disease.

Treatment Options And Surgical Techniques

Definitive management for localized melanoma is surgical — wide local excision with margins determined by Breslow thickness; sentinel node biopsy is performed when indicated.

Advanced disease is treated with systemic immunotherapies (checkpoint inhibitors), targeted therapies for actionable mutations, and stereotactic radiotherapy or surgery for limited metastases.

Surgical excisionWide local excision with guideline-driven margins removes the primary tumor and reduces local recurrence risk; reconstructive techniques restore form and function when lesions are in cosmetically sensitive areas.

Nodal managementSentinel lymph node biopsy identifies microscopic spread; therapeutic lymphadenectomy may be needed for clinically positive nodes combined with adjuvant systemic therapy based on stage.

Systemic therapiesImmune checkpoint inhibitors (eg. anti-PD-1) and BRAF/MEK targeted combinations for BRAF-mutant melanomas have transformed outcomes in metastatic disease and are integrated into stage-appropriate care plans.

Recovery, Risks And Prognosis

Prognosis is closely linked to tumor thickness, ulceration and nodal status; thin, early melanomas have excellent cure rates after excision, while nodal or distant involvement reduces long-term survival but may respond to modern systemic therapy.

Follow-up schedules are risk-adapted and include periodic skin exams and imaging when indicated.
