ADENOID TYPE
Adenoid type is a subtype of squamous cell carcinoma, an aggressive form of skin cancer. It is characterized by the presence of cell clusters that resemble adenoids, or lymphoid tissue. These cell clusters are typically found on the face, neck, and scalp. Adenoid type is usually diagnosed by examining a sample of the affected tissue under a microscope.
Adenoid type squamous cell carcinoma (AdSCC) is a rare but aggressive form of skin cancer that is estimated to make up 1-2% of all skin cancer cases. It typically occurs in individuals between the ages of 30 and 50 years old, and men are more likely to be affected than women. The cause of AdSCC is unknown, but environmental factors such as ultraviolet radiation exposure may be linked to its development.
AdSCC can present with a variety of clinical signs and symptoms, which may include a small flesh-colored or reddish lump, an ulcer, or a flat, thickened patch of skin. The lump or ulcer may be tender to the touch and may bleed easily. Additionally, individuals may experience itching or burning sensations in the affected area.
Diagnosis of AdSCC typically involves a biopsy to examine the affected tissue under a microscope. During this procedure, a sample of the tissue is removed and sent to a laboratory for analysis. In some cases, a computed tomography (CT) scan may be used to look for any evidence of spread of the cancer to other areas of the body.
Adenoid type squamous cell carcinoma is usually treated with surgery and radiation therapy. Surgery is used to remove the affected tissue, while radiation therapy is used to kill any remaining cancer cells. In some cases, chemotherapy or targeted therapy may also be used to treat the cancer.
Adenoid type squamous cell carcinoma is an aggressive form of skin cancer that can be difficult to diagnose and treat. Early recognition and treatment are important for improving outcomes and reducing the risk of recurrence.
