Rapid Remission of a Second Primary Kaposi's Sarcoma With Thalidomide Treatment in a Patient Receiving Adjuvant Chemotherapy for Colon Cancer

2013 Journal of Medical Cases  
Kaposi's sarcoma is a human herpes virus 8 associated-angioproliferative disorder, which is commonly associated with immunocompromised conditions such as those which arise in renal transplant recipients, or in acquired immune-deficiency syndrome (AIDS) cases. It is less well described, however, in patients with solid tumors undergoing adjuvant chemotherapy after surgery.
