How do you identify basal cell carcinoma histology?
Usually, BCCs are well differentiated and cells appear histologically similar to basal cells of the epidermis. Tumor cells of nodular BCC, sometimes called basalioma cells, typically have large, hyperchromatic, oval nuclei and little cytoplasm. Cells appear uniform, and if present, mitotic figures are usually few.
What are the distinguishing characteristics of 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 is a solid basal cell carcinoma?
Basal cell carcinoma (BCC) is a slow growing, locally aggressive tumor that arises from the basal layer of the epidermis. It is the most common cancer in the fair-skinned population [1]. Lifetime risk of developing BCC is approximately 30% and the incidence is continuously increasing worldwide [2].
What is the basis for the classification of cancers?
Doctors classify cancer using the site at which the cancer started or the type of tissue where the cancer originated. For example, a person can have breast cancer, which is usually a type of carcinoma, or cancer that arises from epithelial tissue.
What can BCC be mistaken for?
Basal cell carcinoma is a type of skin cancer that can show up on the skin in many ways. Also known as BCC, this skin cancer tends to grow slowly and can be mistaken for a harmless pimple, scar, or sore.
What can be mistaken for a basal cell carcinoma?
Trichoepithelioma is a benign tumor which can be easily confused with basal cell carcinoma. Since both tumors are histologically similar, it is important to distinguish them correctly as the courses for treatment are very different.
What kind of cancer is found in the pancreas?
This cancer occurs in the lining of the ducts in the pancreas. It’s also possible for adenocarcinoma to develop from the cells that create pancreatic enzymes. When this occurs, it is called acinar cell carcinoma, which accounts for 1 percent to 2 percent of exocrine cancers.
How many people are affected by basal cell carcinoma?
INTRODUCTION Basal cell carcinoma (BCC) constitutes about 70% of keratinocyte tumors that comprise 90% of all malign skin diseases.[1,2] The incidence of BCC is about 2000 cases per 100 000 population, and the morbidity varies depending on the geographic width and the patients’ age, with growing tendency for individuals above 50 years of age.
Can a benign cyst be a precursor to pancreatic cancer?
Cysts and other benign tumors can form in the pancreas, and some can be precursors to pancreatic cancer, including intraductal papillary-mucinous neoplasms (IPMNs). Often, IPMNs and other benign lesions are found when a patient is being scanned for an unrelated medical reason.
How big is a basal cell carcinoma plaque?
Superficial basal cell carcinoma. This version occurs as erythematous plaque with different sizes (from several millimeters to more than 10 cm). It is about 10-30% of basal cell carcinoma and occurs on the body skin.
