Patients that have acquired immunodeficiency syndrome are at increased risk for which of the following neoplasms?

c. Kaposi’s sarcoma

The role of the immune system in the development of neoplastic disease has been the subject of extensive debate. Clinical observations and the results from experimental animal models are not completely congruent. For example, patients with immune deficiency or immunosuppressed transplant recipients are at greater risk for neoplastic disease. Frequently these are tumors of the lymphoreticular system, and only selected nonlymphoid tissues exhibit increased incidence of neoplasia. Patients with acquired immunodeficiency syndrome and some transplant patients are at an increased risk for Kaposi’s sarcoma.
