Many types of skin tumors, both benign (noncancerous) and malignant (cancerous), exist in cats and dogs. Approximately 20–40% of primary skin tumors are malignant in dogs and 50–65% are malignant in cats. Not all forms of skin cancer in cats and dogs are caused by sun exposure, but it can happen occasionally. On dogs, the nose and pads of ...
A mastocytoma in dogs (or mast cell tumor in dogs) is a neoplasm originating from mast cells in the domestic dog, which occurs mainly in the skin and subcutis. Mastocytoma are not only extremely common in dogs, but also tend to be much more malignant in them than in other animal species.
Two types of mast cell tumors have been identified in cats, a mast cell type similar to dogs and a histiocytic type that appears as subcutaneous nodules and may resolve spontaneously. Young Siamese cats are at an increased risk for the histiocytic type, [ 2 ] although the mast cell type is the most common in all cats and is considered to be ...

[1] Mast cell tumors are the most common type of skin cancer in canines. [1] Lymphoma; Prostate cancer; Brain cancer; Hemangiosarcoma is a type of cancer that is ...
BerEp4 has a high sensitivity and specificity in being positive only in BCC cells. [1] BerEp4 is normally negative in squamous epithelium and mesothelium, but otherwise normally positive most epithelial cells of the body. [3] It can also help in distinguishing pulmonary adenocarcinoma (positive BerEp4) from mesothelioma (generally negative BerEp4).
Transitional cell carcinoma, a type of cancer most commonly seen in a dog's bladder, may respond to ivermectin in the same way as human renal cell carcinoma. Unfortunately, there is not yet any ...

Basal cell carcinoma: Clusters of basaloid cells The most common reason to use cytological examination in malignant tumoral diseases is to distinguish basal cell carcinoma from other tumors, such as squamous cell carcinoma and melanoma. Tzanck smear test is 97% sensitivity and 86% specificity for the diagnosis of basal cell carcinoma.
