Can basal cell carcinoma spread to nerves?
These cancers rarely metastasize to lymph nodes or other organs, but they can grow quite large and invade small nerves and local structures. Biopsy can help determine if the basal cell cancer is a low-risk tumor or a high-risk tumor that requires more aggressive treatment.
How do you identify basal cell carcinoma histology?
Histology of basal cell carcinoma A useful distinguishing feature from other basaloid cutaneous tumours is the presence of a mucinous stroma (figure 4). Some tumours may also show foci of regression, seen as areas of eosinophilic stroma with lack of basaloid nests.
What does basal cell carcinoma look like under microscope?
Nodular BCC looks like a dome-shaped bump. It may be pearly or shiny. Typical colors are pink, red, brown, or black. You may see tiny blood vessels in the lesion.
What are the distinguishing characteristics of basal cell carcinoma?
A brown, black or blue lesion — or a lesion with dark spots — with a slightly raised, translucent border. A flat, scaly patch with a raised edge. Over time, these patches can grow quite large. A white, waxy, scar-like lesion without a clearly defined border.
Is basal cell carcinoma painful?
As it develops, basal cell carcinoma can cause several significant symptoms. However, basal cell carcinomas typically don’t hurt, and patients rarely feel anything out of the ordinary. Instead, the warning signs are primarily visual.
What does Morpheaform basal cell carcinoma look like?
Such lesions appear as flat or slightly depressed, fibrotic, and firm. The tumor appears as a white or yellow, waxy, sclerotic plaque that rarely ulcerates. The morpheaform (sclerosing) type of basal cell carcinoma is often the most difficult type to diagnose, as it bears little resemblance to the typical nodular BCC.
What does infiltrative basal cell carcinoma look like?
Infiltrating or morpheaform BCCs tend to appear as scar-like growths on the skin. They can be slightly shiny, and sometimes have telangiectasias, sores (erosions), or scabs on their surfaces. These skin changes can be subtle. Superficial BCCs often appear as pink or red dry, scaly spots.
What does a carcinoma look like?
It can be pink, brown, or black. At first, a basal cell carcinoma comes up like a small “pearly” bump that looks like a flesh-colored mole or a pimple that doesn’t go away. Sometimes these growths can look dark. Or you may also see shiny pink or red patches that are slightly scaly.
How can you tell the difference between squamous cell carcinoma and basal cell carcinoma?
Basal cell carcinoma most commonly appears as a pearly white, dome-shaped papule with prominent telangiectatic surface vessels. Squamous cell carcinoma most commonly appears as a firm, smooth, or hyperkeratotic papule or plaque, often with central ulceration.
What does basal cell carcinoma look like at low magnification?
The key feature of basal cell carcinoma at low power magnification is of a basaloid epithelial tumour arising from the epidermis (figure 1). The basaloid epithelium typically forms a palisade with a cleft forming from the adjacent tumour stroma (figure 2).
What is basal cell carcinoma?
Basal Cell Carcinoma – pre-removal of a suspicious dark brown mole on the abdomen of a young woman. Skin tumors, moles and spots, 3d section of the skin layer Skin tumors, moles and spots, 3d section of the skin layer.
What is squamous cell carcinoma basal-cell carcinoma and melanoma?
Squamous cell carcinoma, basal-cell cancer and Melanoma. Skin cancer: Squamous cell carcinoma (disease of older cells on the surface skin), basal-cell cancer (begins in the basal cells) and Melanoma (arises in the pigment cells – melanocytes). layers of human skin and healthy epidermis.

What is photodynamic therapy for basal cell carcinoma?
The procedure is known as Photodynamic Therapy (PDT). It has a success rate comparable to surgery but gives a much better cosmetic result. basal cell carcinoma stock pictures, royalty-free photos & images
