Nodular basal cell carcinoma is the most common type of basal cell skin cancer. Generally, it looks like a smooth, round pimple and may be pale yellow or gray in color. With the slightest bump or injury, it may bleed.
Pigmented basal cell carcinoma can be similar to nodular basal cell carcinoma, but appears more often in people with dark eyes and hair. The nodules are brown or black and can be mistaken for melanoma.
Superficial basal cell carcinoma is a less-common form of basal cell skin cancer. This form is characterized by a slow-spreading skin lesion. It can have slightly crusted surfaces, bordered by small thread-like formations. These lesions usually develop on the trunk, but can also grow on the neck and face.
Sclerosing, or morpheaform, basal cell carcinoma is another less-common type of BCC. It may look like a scar and be white or yellow in color. It usually grows quickly and can be almost an inch in length within a few months.
Two rare forms of BCC are fibroepothelioma and cystic basal cell carcinoma. Fibroepothelioma consists of reddish lesions that appear on a person’s back. Cystic basal cell carcinoma is a variant of nodular basal cell carcinoma and filled with a gelatin-like fluid.
