Angiosarcoma can arise in association with which condition?

• A. Chronic pancreatitis
• B. Osteoporosis
• C. Lymphedema
• D. Diabetes mellitus

Answer: (C)

Angiosarcoma tends to develop in regions with long-standing lymphedema, where chronic lymphatic obstruction creates an environment that promotes malignant transformation of endothelial cells. This is classically seen as Stewart-Treves type angiosarcoma after mastectomy with lymph node dissection or radiation, highlighting how persistent lymphatic stasis and local immune dysfunction can drive these endothelial tumors. The other conditions listed—chronic pancreatitis, osteoporosis, and diabetes mellitus—do not create the chronic lymphatic swelling or local endothelial milieu that predisposes to angiosarcoma, so they are not commonly associated with this malignancy.
