Medical Intelligence & Overview
Kaposi's sarcoma of soft tissue (ICD-10 code C46.1) is a type of cancer that develops in the soft tissues of the body, including blood vessels, connective tissues, fascia, ligaments, lymphatic tissues, and muscles. This condition is characterized by abnormal growth of cells that form tumors, which can affect various parts of the soft tissue structures. While it can occur in anyone, it is most commonly associated with individuals who have compromised immune systems, such as those living with HIV/AIDS.

Key Symptoms: Purple, red, or brown patches or nodules on the skin or within soft tissues. Swelling or lumps in areas like the limbs, face, or internal organs. Pain or discomfort in affected areas. In advanced cases, internal organ involvement might lead to symptoms such as difficulty breathing, fatigue, or weight loss. Lesions may enlarge or multiply over time if untreated.
Diagnostic & Treatment
