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. [10] cSCC typically presents as a hard lump with a scaly surface, though it may also present as an ulcer. [1]
The blue colour is caused by the pigment being deep in the skin. [4] Diagnosis is by visualisation and dermoscopy. [4] A biopsy is sometimes performed, or the whole lesion surgically removed. [3] The outcome is generally good but there is a small chance of cancerous transformation. [3] Differential diagnosis includes dermatofibroma and melanoma ...
Atopic dermatitis (AD), also known as atopic eczema, is a long-term type of inflammation of the skin. [2] AD is also often called simply eczema but the same term is also used to refer to dermatitis, the larger group of skin conditions.
Lentigo maligna is a histopathological variant of melanoma in situ. [6] Lentigo maligna is sometimes classified as a very early melanoma, [7] and sometimes as a precursor to melanoma. [8] When malignant melanocytes from a lentigo maligna have invaded below the epidermis, the condition is termed lentigo maligna melanoma. [2]
Extramammary Paget's disease (EMPD) is a rare and slow-growing malignancy which occurs within the epithelium [1] and accounts for 6.5% of all Paget's disease. [2] The clinical presentation of this disease is similar to the characteristics of mammary Paget's disease (MPD). [3]
With doctors who are experts in dermatoscopy, the diagnostic accuracy for melanoma is significantly better than those who do not have any specialized training. [3] Thus, there is considerable improvement in the sensitivity (detection of melanomas) as well as specificity (percentage of non-melanomas correctly diagnosed as benign), compared with naked eye examination.
An equine melanoma is a tumor that results from the abnormal growth of melanocytes in horses. Unlike in humans, melanomas in horses are not thought to be caused by exposure to ultraviolet light. [1] Melanomas are the third most common type of skin cancer in horses, with sarcoids being the first most prevalent and squamous-cell carcinoma being ...
Congenital nevus. Note the variable coloration and slightly irregular border. The congenital melanocytic nevus appears as a circumscribed, light brown to black patch or plaque, potentially very heterogeneous in consistency, covering any size surface area and any part of the body.
