Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]
neglected squamous cell carcinoma skin of scalp Advanced squamous cell carcinoma, excision specimen. Note invasion subcutaneous tissue. Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma.
These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts. [1] The squamous-cell carcinomas of different body sites can show differences in their presented symptoms, natural history, prognosis, and response to treatment.
It can also affect other parts of the body. Dr. Thosani says the scalp is the most affected by psoriasis, but the elbows and knees can experience symptoms as well. Beyond scabs, symptoms of ...

[citation needed] Generally, cutaneous lesions are spread over the body, but some cases have only a few lesions which are limited to one extremity.
Keratoacanthoma is commonly found on sun-exposed skin, often face, forearms and hands. [2] [3] It is rarely found at a mucocutaneous junction or on mucous membranes. [2] Keratoacanthoma may be difficult to distinguish visually from a skin cancer. [4] Under the microscope, keratoacanthoma very closely resembles squamous cell carcinoma. In order ...
