Summary
Squamous cell carcinomas developed from multiple follicular cysts in a Catalan shepherd dog. Metastatic cancer was found in the lungs and front paw bones after 29 months.
Area of Science:
- Veterinary Pathology
- Oncology
Background:
- Cutaneous follicular cysts can be benign or malignant.
- Squamous cell carcinoma (SCC) is a common skin cancer in dogs.
Observation:
- A 6-year-old Catalan shepherd cross dog presented with multiple cutaneous follicular cysts.
- The dog developed invasive squamous cell carcinomas originating from these cysts.
Findings:
- The dog died 29 months post-diagnosis.
- Metastatic SCC was identified in the lungs and metacarpal bones (1 and 2) of the left front paw.
Implications:
- This case highlights the potential for follicular cysts to undergo malignant transformation.
- Early detection and understanding of SCC metastasis in dogs are crucial for treatment and prognosis.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

02:21Cancers Originate from Somatic Mutations in a Single Cell

Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...
