Causes
Squamous cell carcinomas arise from the epithelial cellsEpithelial cells are the cells that make up epithelial tissue. They line the outer surfaces of the body, as well as internal cavities, ducts, and organs, and perform functions such as protection, absorption, secretion, and filtration. that form the outer layer of the skin. These cells can undergo genetic mutations due to various factors, leading to uncontrolled growth. In dogs, these Tumors occur particularly often on the toes, as they are frequently exposed to mechanical stressStress refers to the state of an organism reacting to external stimuli or demands. In veterinary medicine, stress can have physical or psychological effects on animals, impacting their health and well-being. and potential damage.
The exact cause of squamous cell carcinomaA carcinoma is a type of cancer that originates in the epithelial cells that line the inner and outer surfaces of the body. Carcinomas are the most common form of cancer. in dogs is not fully understood, but there are some known risk factors. These include chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. skin irritation, UV radiation, viruses, and genetic predispositions. Certain breeds such as the Standard Poodle, Giant Schnauzer, and Labrador Retriever show a higher susceptibility to this type of cancerCancer refers to the uncontrolled proliferation of cells that can lead to tumors or spread throughout the body. Various types of cancer occur in dogs and cats, ranging from skin cancer to lymphomas..
ChronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. Inflammatory conditions or injuries to the toes can also increase the risk, as they stimulate cell regeneration and thereby increase the likelihood of errors in cell division. Long-term exposureExposure refers to the Contact with or subjection to certain substances, environmental factors, or pathogens. In veterinary medicine, this can include Contact with toxins, allergens, or infectious agents that can cause health problems in dogs and cats. to UV radiation is another important risk factor, as it can cause direct DNADNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for the development, function, and reproduction of all known living organisms and many viruses. It is located in the cells of an organism and contains the information for heredity. damage in skin cells.
Symptoms
A typical symptom of digital squamous cell carcinoma is a non-healing wound or ulcer on the toe, which may sometimes bleed or ooze. The affected toe may be swollen, and the dog may show Lameness or Pain when walking.
Other symptoms may include a deformation or enlargement of the affected toe. Dogs may also show signs of general malaise, such as reduced appetite or lethargy, especially if the cancerCancer refers to the uncontrolled proliferation of cells that can lead to tumors or spread throughout the body. Various types of cancer occur in dogs and cats, ranging from skin cancer to lymphomas. is advanced or has metastasized.
In some cases, a secondary infectionA secondary infection occurs when an already weakened individual suffers an additional infection, often because the immune system is impaired by the primary infection. of the affected area may occur, which can lead to increased Pain and Pus formation. This can make diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests.

Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of digital squamous cell carcinomaA carcinoma is a type of cancer that originates in the epithelial cells that line the inner and outer surfaces of the body. Carcinomas are the most common form of cancer. usually begins with a thorough clinical examination by the veterinarian. Particular attention is paid to the affected toe, with the veterinarian looking for signs of Swelling, ulcers, or deformities.
To make a definitive diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients., a biopsyA biopsy is a medical procedure in which a small amount of tissue is removed from the body to be examined under a microscope for signs of disease. Biopsies can help diagnose cancer and other conditions. is usually required. In this procedure, a tissue sample is taken from the affected area and examined histologically to confirm the presence of cancerous changes.
In addition, imaging techniques such as X-rays or MRI can be used to assess the extent of bone erosion or possible metastasesA metastasis is a secondary tumor that originates from a primary, malignant tumor in another part of the body. Metastases indicate that cancer has spread in the body.. In some cases, additional tests such as blood tests or ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow. examinations may be necessary to assess the dog’s general health and rule out other possible diseases.
Therapy
The treatment of digital squamous cell carcinoma depends on the severity and progressionProgression refers to the advancement or worsening of a disease over time. It describes an increase in the severity or extent of the disease symptoms. of the disease. In most cases, surgical removal of the tumorA tumor is an abnormal growth of tissue that can be benign or malignant.
