Infiltrative Basal Cell Carcinoma - Causes & Symptoms

Infiltrative basal cell carcinoma is a type of skin cancer that grows deeply into the skin layers. It develops when the basal cells in the skin mutate and grow uncontrollably. These cells can infiltrate surrounding tissues and structures, leading to potential complications. The exact cause of infiltrative basal cell carcinoma is not fully understood, but it is believed to be primarily due to exposure to ultraviolet (UV) radiation from the sun or tanning beds over a prolonged period. Genetics and a history of frequent sun exposure also play a role in increasing the risk of developing this type of skin cancer. Protecting your skin from excessive sun exposure and avoiding tanning beds can help reduce the risk of developing infiltrative basal cell carcinoma. Regular skin checks and early detection.

What Are the Symptoms of Infiltrative Basal Cell Carcinoma

Infiltrative basal cell carcinoma can present with various symptoms that may include a pearly or waxy bump, a flat, flesh-colored or brown scar-like lesion, a firm, red nodule, or a sore that continuously heals and reopens. These lesions may bleed easily and fail to resolve, often growing larger over time. Some individuals may also experience itchiness, tenderness, or pain in the affected area. It is crucial to consult a healthcare provider promptly if you notice any persistent skin abnormalities or changes to ensure timely diagnosis and appropriate management.

Causes of Infiltrative Basal Cell Carcinoma

The main contributing factors include excessive sun exposure, particularly to ultraviolet (UV) radiation, which can damage the skin cells and trigger cancerous changes. Genetic predisposition plays a role as well, with individuals having a family history of skin cancer being at higher risk. Certain environmental factors, such as exposure to carcinogens or radiation, can also contribute to the development of infiltrative basal cell carcinoma.  Additionally, a weakened immune system and older age can increase susceptibility to this type of skin cancer.

Types Of Infiltrative Basal Cell Carcinoma

These include morpheaform, micronodular, and infiltrative basal cell carcinoma.  Morpheaform BCC appears as a flat, scar-like lesion with indistinct margins, making it challenging to detect.  Micronodular BCC comprises small, rounded tumor nodules that infiltrate deeply into the skin.  Infiltrative BCC exhibits invasive growth patterns, spreading into surrounding tissues.  These types of infiltrative basal cell carcinoma require careful diagnosis and management to prevent recurrence and ensure effective treatment.

Types of Infiltrative Basal Cell Carcinoma:

Risk Factors

Several risk factors can increase the likelihood of developing this aggressive form of basal cell carcinoma.  These risk factors include excessive sun exposure, especially with a history of sunburns, fair skin, a weakened immune system, a family history of skin cancer, exposure to environmental toxins like arsenic, and previous radiation therapy.  It's essential to be aware of these risk factors and take preventive measures, such as sun protection and regular skin checks, to reduce the chances of developing infiltrative basal cell carcinoma.

Diagnosis of Infiltrative Basal Cell Carcinoma

Firstly, a thorough physical examination of the skin lesion is conducted, followed by a biopsy to confirm the presence of cancerous cells.  Imaging techniques like dermoscopy or confocal microscopy may be used to assess the extent of infiltration into surrounding tissues.  Additionally, advanced imaging modalities such as ultrasound or MRI can help determine the depth and size of the tumor.  Once the diagnosis is confirmed, staging tests may be performed to assess if the cancer has spread to other parts of the body.  Prompt and accurate diagnosis is crucial for determining the most appropriate treatment plan for infiltrative basal cell carcinoma.

Treatment for Infiltrative Basal Cell Carcinoma

Treatment options for infiltrative basal cell carcinoma typically depend on the extent and location of the tumor, as well as the overall health of the patient. Common approaches include surgical excision, Mohs micrographic surgery, cryotherapy, radiation therapy, and topical medications such as imiquimod or fluorouracil. 

In some cases, a combination of these methods may be used to ensure complete removal of the cancerous cells while preserving healthy tissue. Regular follow-up visits are essential to monitor for recurrence and ensure the effectiveness of the chosen treatment. Consulting with a dermatologist or oncologist is crucial in determining the most appropriate course of action for each individual case.

Infiltrative basal cell carcinoma can be treated through various methods, depending on the extent and location of the tumor. Surgical excision is a common approach, where the tumor is cut out along with a margin of healthy tissue to ensure complete removal. Mohs surgery is another specialized technique that involves removing thin layers of tissue and examining them under a microscope during the procedure to ensure minimal damage to surrounding healthy tissue. 

Radiation therapy may be used for tumors that are difficult to treat surgically or in cases where surgery is not feasible. Topical medications such as imiquimod or 5-fluorouracil can be prescribed for superficial basal cell carcinomas. Photodynamic therapy is a non-invasive option that involves applying a photosensitizing agent.
