Melanoma

Melanoma is a malignant neoplasm originating from melanocytes, the pigment-producing cells of the epidermis. While less common than basal or squamous cell carcinomas, melanoma is the most lethal form of skin cancer due to its high propensity for early metastasis via the lymphatic and hematogenous routes.

Melanoma arises from the malignant transformation of melanocytes. Primary drivers include intermittent intense ultraviolet (UV) radiation exposure, genetic predisposition, and impairment of DNA repair mechanisms.

Melanoma involves the uncontrolled proliferation of melanocytes. Progression involves an initial "radial growth phase" (horizontal spread) followed by a "vertical growth phase" (invasion into the dermis), which correlates with metastatic potential. Common mutations include BRAF (V600E), NRAS, and c-KIT, leading to the constitutive activation of the MAPK/ERK signaling pathway.

It predominantly affects fair-skinned populations. Global incidence has risen significantly over the past decades. Peak incidence occurs between ages 50–60, though it is one of the most common cancers in young adults (ages 25–40).

• History of blistering sunburns.
• Fair skin, light hair, or blue/green eyes.
• Presence of dysplastic nevi.
• Family history of melanoma.
• Immunosuppression.
• Use of tanning beds.

A. Early Symptoms

• New or changing pigmented lesion.


• Asymmetry of a mole. B. Common Symptoms


• Irregular borders of a skin lesion.


• Multiple colors (brown, black, blue, red, white).


• Diameter greater than 6 mm. C. Advanced Symptoms


• Ulceration or bleeding.


• Itching or pain at the site.


• Enlarged regional lymph nodes. D. Emergency Symptoms


• Neurological deficits (brain metastasis).


• Shortness of breath (pulmonary metastasis).


• Jaundice (liver metastasis).

Inspection reveals the ABCDE criteria: Asymmetry, Border irregularity, Color variation, Diameter >6mm, and Evolution. Palpation may reveal induration or associated lymphadenopathy.

A. Clinical Assessment: Dermoscopy.
B. Laboratory Testing: Serum LDH (marker for advanced disease).
C. Imaging Studies: PET/CT for staging.
D. Functional Tests: Not applicable.
E. Biopsy Findings: Excisional biopsy is the gold standard (Breslow depth assessment).
F. Genetic Testing: BRAF mutation analysis.
G. Differential Diagnosis: Seborrheic keratosis, pigmented basal cell carcinoma, atypical nevi.

Test Name: Lactate Dehydrogenase (LDH)
Type: Blood Test
Purpose: Staging/Prognosis
Expected Findings: Elevated levels
Interpretation: Suggests metastatic burden

• PET/CT: Used for systemic staging; detects high metabolic activity in distant metastasis.
• MRI: Preferred for evaluating central nervous system metastasis.

Distinguished from benign seborrheic keratosis (lack of pigmentation features) and dysplastic nevi (by clinical stability and histopathology).

Metastasis to brain, lungs, liver, and bones; recurrence; psychological distress.

A. Lifestyle Modifications: UV protection.
B. Preventive Measures: Broad-spectrum sunscreen, protective clothing.
C. Medical Treatment: * Checkpoint inhibitors (Pembrolizumab, Nivolumab).

• BRAF inhibitors (Dabrafenib, Vemurafenib).

Prognosis is primarily dependent on Breslow thickness. Localized melanoma has a 5-year survival rate of ~99%, while metastatic disease survival drops to ~20–30%.

Avoidance of UV exposure, regular full-body skin examinations.
