Squamous Cell Carcinoma

Squamous Cell Carcinoma (SCC) is the second most common form of skin cancer, arising from the malignant proliferation of keratinocytes in the epidermis. While generally localized and slow-growing, it possesses the potential for local tissue destruction and, if left untreated, metastatic spread to lymph nodes and distant organs.

The primary cause is cumulative exposure to ultraviolet (UV) radiation (UVA/UVB), leading to DNA mutations. Chronic inflammation, HPV infection, chemical carcinogens (arsenic, hydrocarbons), and ionizing radiation are also recognized triggers. Genetic factors, particularly mutations in the TP53 tumor suppressor gene, play a pivotal role.

SCC originates in the squamous cells of the epidermis. UV radiation induces pyrimidine dimers, resulting in mutations that bypass cell-cycle checkpoints. This leads to unregulated cellular proliferation and the maturation of atypical, "prickle" cells that invade the basement membrane and penetrate the dermis.

SCC affects millions annually, with incidence rising due to an aging population and increased UV exposure. It is more common in males, fair-skinned individuals (Fitzpatrick skin types I-II), and those aged 60 and older.

• Prolonged UV exposure (sunlight/tanning beds)
• Fair complexion and history of sunburns
• Immunosuppression (organ transplant recipients)
• Chronic skin wounds or scars (Marjolin's ulcer)
• Human Papillomavirus (HPV) infection
• Previous history of actinic keratosis

A. Early Symptoms

• Persistent, scaly red patch


• Small, firm, flesh-colored or reddish bump


• Wart-like growth B. Common Symptoms


• Scaly, erythematous plaque


• Crusted or bleeding lesion


• Tender, non-healing ulcer C. Advanced Symptoms


• Deep ulceration with rolled borders


• Pain radiating from the lesion


• Palpable regional lymphadenopathy D. Emergency Symptoms


• Rapid growth, severe localized pain, or neurological deficits (nerve involvement)

Inspection reveals a hyperkeratotic, erythematous, or crusted papule/nodule. Palpation often identifies a firm, indurated base. Lymph node assessment is mandatory to rule out regional metastasis.

A. Clinical Assessment: Dermatoscopy for vascular patterns.
B. Laboratory Testing: Generally not required for localized disease.
C. Imaging Studies: Ultrasound or CT/MRI if nodal involvement is suspected.
D. Functional Tests: Not applicable.
E. Biopsy Findings: Full-thickness shave or punch biopsy showing invasive nests of atypical keratinocytes with keratin pearls.
F. Genetic Testing: Primarily for research or targeting specific pathways in metastatic cases.
G. Differential Diagnosis: Actinic keratosis, basal cell carcinoma, seborrheic keratosis, pyogenic granuloma.

Complete Blood Count (CBC)
Type: Blood Test
Purpose: Evaluate overall health and rule out systemic issues.
Expected Findings: Usually normal.
Interpretation: Normal findings are standard for localized SCC.

CT Scan/MRI
Purpose: Staging.
Typical Findings: Evidence of subcutaneous invasion or nodal involvement.
Clinical Importance: Crucial for planning radical excision or adjuvant therapy.

Basal Cell Carcinoma (pearly border), Actinic Keratosis (pre-malignant, no invasion), Melanoma (pigmented), Psoriasis (usually symmetric, non-invasive).

Metastasis (lymphatic/hematogenous), localized infection, extensive tissue loss following resection, and cosmetic disfigurement.

A. Lifestyle Modifications: UV protection, smoking cessation.
B. Preventive Measures: Broad-spectrum SPF 50+, protective clothing.
C. Medical Treatment: Topical 5-fluorouracil or imiquimod for superficial lesions; PD-1 inhibitors (Cemiplimab) for metastatic disease.
D. Surgical Treatment: Mohs micrographic surgery (gold standard), wide local excision, or curettage and electrodesiccation.
E. Interventional Procedures: Radiation therapy for non-surgical candidates.
F. Rehabilitation: Wound care and physical therapy for extensive tissue removal.
G. Emergency Management: Surgical resection of necrotic or highly invasive tumors.

Excellent for localized disease (5-year survival >95%). High-risk variants or those with perineural invasion carry a poorer prognosis if metastatic progression occurs.

Sun avoidance, regular skin self-exams, and annual dermatology screenings for high-risk individuals.
