title: Regression of Kaposi's sarcoma after reduction of immunosuppressive therapy in a heart transplant patient.
abstract: The de novo development of Kaposi's sarcoma, confirmed by lymph node biopsy 17 months after heart transplantation in an 18-year-old patient, is described. Constitutional symptoms and axillary and inguinal lymphadenopathy were the presenting features. Surveillance for systemic involvement was negative, and the tumor seemed to be confined to the lymphoreticular system alone. Chemotherapy with vincristine and cyclophosphamide resulted in severe leukopenia and was discontinued. Immunosuppressive therapy, consisting of cyclosporine and methylprednisolone, was gradually reduced, resulting in regression of symptoms and lymphadenopathy. One year later the patient was symptom free, and only one extremely small inguinal lymph node was palpable. Microscopic examination of this node, however, revealed persistent Kaposi's sarcoma. The patient's immunosuppressed state would now appear to be sufficient to prevent acute rejection and yet insufficient to lead to growth and spread of the tumor.
