Basal-cell carcinoma (BCC), also known as basal-cell cancer, basalioma [7] or rodent ulcer, [8] is the most common type of skin cancer. [2] It often appears as a painless raised area of skin, which may be shiny with small blood vessels running over it. [1] It may also present as a raised area with ulceration. [1]
It usually presents as a hard lump with a scaly top but may also form an ulcer. [2] Melanomas are the most aggressive. Signs include a mole that has changed in size, shape, color, has irregular edges, has more than one color, is itchy or bleeds. [3] More than 90% of cases are caused by exposure to ultraviolet radiation from the Sun. [4]
An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract. An ulcer that appears on the skin is ...

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.
The median time interval between the onset of symptoms and the diagnosis was 6 years, with a range of 26 days to 14 years. This suggests that the symptoms of MAGIC syndrome may manifest relatively long after the initial onset of symptoms. During the course of MAGIC syndrome, the signs and symptoms of BD may typically occur before those of RP. [4]
The lesions mostly appear on the upper lip as ulcers, but they also develop on the gums and palate. Other locations like foot pads are not exceptional and are typical for developing plaques instead of ulcers. [9] Such plaques may be itchy and swelling. In the case of oral ulceration, bleeding, pain and loss of appetite may be present. [10]
In 1889, Sir Jonathan Hutchinson described a crateriform ulcer on the face”. [16] In 1936, the same condition was renamed "molluscum sebaceum" by MacCormac and Scarf. [ 17 ] Later, the term “keratoacanthoma” was coined by Walter Freudenthal [ 18 ] [ 19 ] and the term became established by Arthur Rook and pathologist Ian Whimster in 1950.
