basal cell carcinoma

Basal cell carcinoma (BCC) is a type of skin cancer that affects millions of people worldwide. Here are some key facts about BCC:

• Most common form of skin cancer: BCC is the most common type of skin cancer, accounting for approximately 80% of all skin cancer cases [1].
• Caused by overproduction of basal cells: BCC occurs when there is an abnormal growth of basal cells in the top layer of the skin (epidermis) [3].
• Common locations: BCC most often develops on areas of skin exposed to the sun, such as the face, head, neck, chest, arms, and legs [1][6].
• Symptoms: The symptoms of BCC can vary, but common signs include:
  • A persistent spot or bump that appears on the skin
  • A pearly or waxy appearance
  • White or light pink color
  • Flesh-colored or brown color
  • Red, scaly patch of skin [7][9]
• Types: There are several types of BCC, including:
  • Nodular BCC: This is the most common type and appears as a small, shiny bump.
  • Superficial BCC: This type affects the outer layer of the skin and can appear as a red or pink patch.
  • Pigmented BCC: This type occurs in dark-skinned individuals and can be pigmented [8]
• Treatment: When found early, BCC is highly treatable. Treatment options include surgery, radiation therapy, and topical treatments [4][5].

Common Signs and Symptoms of Basal Cell Carcinoma

Basal cell carcinoma (BCC) is a type of skin cancer that can appear on various parts of the body, including the face, neck, and head. It's essential to recognize the warning signs and symptoms to seek medical attention promptly.

• Small, shiny bumps or growths: These are often red or pink in color, but may appear brown or blue in people with darker skin tones [6].
• Lumps, bumps, pimples, scabs, or scaly lesions: BCC can manifest as a lump or bump on the skin that may be slightly see-through (translucent) and have a pearly appearance [4].
• Red or scaly patches of skin: These areas may or may not be itchy or painful and can appear on any part of the body, but are more common on the face, neck, and head [5].
• A small, smooth, shiny, or pale growth: BCC can also present as a waxy-looking lump or a red patch or irritated area [7].

Additional Warning Signs

• An open sore that does not heal, and may bleed, ooze, or crust [1]
• A reddish patch or irritated area on the face, chest, or other areas of the body [2]

It's crucial to note that these signs and symptoms can be similar to those of other skin conditions. If you suspect you have basal cell carcinoma, consult a dermatologist for an accurate diagnosis and treatment plan.

Diagnostic Tests for Basal Cell Carcinoma

Basal cell carcinoma (BCC) can be diagnosed through a combination of physical examination, medical history, and diagnostic tests.

• Physical Examination: A dermatologist will conduct a general physical exam to look for any skin changes or abnormalities. They may also use a technique called dermoscopy (also known as dermatoscopy, epiluminescence microscopy) to examine the skin more closely [1].
• Medical History: Your doctor will ask questions about your medical history, including any previous skin cancers or conditions that may be relevant to your current symptoms [2].
• Skin Biopsy: A skin biopsy is often required to confirm the diagnosis and determine the histologic subtype of BCC. Most often, a shave biopsy is performed, where a small sample of tissue is removed from the affected area and examined under a microscope [6].

Further Testing

If the doctor sees cancerous basal cells during the examination, the diagnosis is basal cell carcinoma. After the doctor examines the removed skin under a microscope, they can confirm the diagnosis and determine the best course of treatment [3].

In some cases, further testing may be required to rule out other conditions or to determine the extent of the disease. This may include imaging tests such as X-rays or CT scans.

Treatment Options for Basal Cell Carcinoma

Basal cell carcinoma (BCC) can be treated using various methods, including drug treatments. Here are some effective options:

• Targeted Drugs: Targeted drugs, such as vismodegib (Erivedge), can be used to treat advanced or recurrent BCCs [2]. These drugs work by inhibiting the hedgehog pathway, which is involved in the growth and spread of cancer cells.
• Topical Chemotherapy: Topical chemotherapy, such as fluorouracil (Efudex), can be used to treat superficial BCCs [6]. This treatment involves applying a cream or gel directly to the affected area.
• Imiquimod Cream: Imiquimod cream (Aldara) is another topical therapy drug that can be used to treat BCC [8][9]. It works by stimulating the immune system to attack cancer cells.

Other Treatment Options

In addition to drug treatments, other options for treating BCC include:

• Surgery: Surgery is often the most common treatment option for BCC, involving the removal of all cancerous tissue and some surrounding healthy tissue [5].
• Radiation Therapy: Radiation therapy can also be used to treat BCC, especially in cases where surgery is not possible or preferred [3].

Statistics on Topical Treatments

According to a study, topical anti-infectives are among the most commonly prescribed treatments for various skin conditions, including BCC [10]. In fact, 8.8% of patients with BCC were treated with topical anti-infectives.

Basal Cell Carcinoma (BCC) Differential Diagnosis

Basal cell carcinoma, a type of skin cancer, can be challenging to diagnose due to its varying presentations and similarities with other skin conditions. Here are some key differential diagnoses for BCC:

• Actinic Keratosis: A precancerous condition caused by prolonged sun exposure, which can appear as small, rough patches on the skin [1].
• Bowen Disease: An early form of squamous cell carcinoma that can mimic BCC in its appearance and behavior [2].
• Cutaneous T-Cell Lymphoma: A rare type of lymphoma that can present with skin lesions similar to BCC [3].
• Fibrous Papule of the Face: A benign growth that can be mistaken for a basal cell carcinoma due to its similar appearance on the face [4].
• Juvenile Nasopharyngeal Angiofibroma: A rare, non-cancerous tumor that can appear as a nasal mass and may be confused with BCC in its early stages [5].

Clinical Features of Basal Cell Carcinoma

BCC typically presents as a:

• Translucent nodule, often with telangiectatic vessels being very evident [6].
• Nodular growth that can expand over time, sometimes accompanied by ulceration or bleeding.
• Pigmented BCC, which can appear as a brown or black spot on the skin.

Diagnostic Considerations

When suspecting basal cell carcinoma, it's essential to consider these differential diagnoses and perform a thorough clinical examination. A histological diagnosis through incisional biopsy is usually required for confirmation [8].
