Kaposi's sarcoma (KS) is indeed more hemorrhagic than often acknowledged, and the bleeding complications can be severe, especially in visceral forms and advanced disease. Hemorrhagic Nature of KS KS lesions are highly vascular tumors, composed of proliferating spindle cells and irregular, blood-filled vascular spaces that frequently leak red blood cells, causing extravasation and giving rise to the characteristic color and potential for hemorrhage. Bleeding is a well-documented complication, particularly with lesions in mucosal surfaces (e.g., GI tract, mouth) and lungs—these sites can result in life-threatening hemorrhage, sometimes requiring transfusion or invasive intervention. Underestimation of Hemorrhagic Risk While textbooks and guidelines often focus on KS's appearance and systemic complications, clinical reports confirm that lesions "bleed easily, causing ulceration, necrosis, and tissue discoloration...
