Kaposi's sarcoma: a reversible hyperplasia.
Kaposi's sarcoma has many unusual features: for example, the pronounced male preponderance; its appearance in "crops" rather than as primary tumour with metastases; a substantial rate of spontaneous remission; the predictability of involved sites; the lack of aneuploidy; and the strong association with immunodeficiency. These features and other evidence suggest that it is not a malignant neoplasm but a benign, potentially controllable and reversible hyperplasia.
