Is pulmonary KS (Kaposi Sarcoma) considered reportable?

Pulmonary Kaposi Sarcoma (KS) is indeed categorized as malignant, which validates the selected answer. KS is a type of cancer that arises from the endothelial cells and typically presents in a multifocal manner, particularly in immunocompromised individuals, such as those with HIV/AIDS. When KS involves the lungs, it is part of the broader spectrum of malignancies attributed to this disease. The World Health Organization classifies KS as a malignancy, and therefore, it is important for healthcare providers and cancer registrars to report cases of pulmonary KS due to its serious implications for patient health and treatment options. This classification as malignant also reflects its behavior, potential for metastasis, and the necessity of monitoring and treating the condition appropriately.
