Engelbreth-Holm-Swarm (EHS) sarcoma

Engelbreth-Holm-Swarm (EHS) sarcoma is a rare type of tumor that develops from connective tissue cells, often in laboratory animals like mice for research. It contains various tissue-like structures, including muscle, cartilage, and bone, within a gelatinous or fibrous mass. EHS sarcoma is known for its complex, disorganized tissue arrangement and is primarily used in scientific studies related to cancer and tissue growth. Although it mostly affects animals in research settings, understanding it helps scientists learn more about how tumors grow and develop, which can inform future cancer treatments.
