Aetiology
Sclerosing basal cell carcinoma (SBCC) is a rare type of skin cancer that is caused by exposure to ultraviolet (UV) light from the sun and other sources. The UV light damages the DNA in skin cells, leading to the formation of abnormal cells that can grow out of control and form a tumor.
Diagnosis
SBCC can be difficult to diagnose because it often looks like a benign mole or skin tag. Diagnosis is usually made through a biopsy of the affected area. The biopsy will show the presence of abnormal cells that are characteristic of SBCC.
Differential diagnosis
SBCC should be distinguished from other types of skin cancer such as squamous cell carcinoma and melanoma. It should also be distinguished from benign skin growths such as warts and skin tags.
Treatment
Treatment for SBCC usually involves surgical removal of the tumor. Other treatments such as cryotherapy, radiation therapy, and chemotherapy may also be used to treat SBCC.
Prognosis
The prognosis for SBCC is usually good. If the tumor is removed completely, there is a low risk of recurrence. However, if the tumor is not removed or if it is not treated properly, it can spread to other parts of the body and become life-threatening.
