Kaposi's sarcoma:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
The exact cause of Kaposi's sarcoma is unknown, but the disease may be related to immunosuppression. Genetic or hereditary predisposition is also suspected. In people with AIDS, Kaposi's sarcoma is caused by an interaction between the human immunodeficiency virus (HIV), immune system suppression, and human herpesvirus-8 (HHV-8).
Occurrence has been linked with sexual transmission of HIV and HHV-8. Approximately 3 out of every 100,000 people develop Kaposi's sarcoma each year.

Malignant spinal neoplasms:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
Primary tumors of the spinal cord may be extramedullary (occurring outside the spinal cord) or intramedullary (occurring within the cord itself). Extramedullary tumors may be intradural (meningiomas and schwannomas), which account for 60% of all primary malignant spinal cord neoplasms, or extradural (metastatic tumors from breasts, lungs, prostate, leukemia, or lymphomas), which account for 25% of these malignant neoplasms.
Intramedullary tumors, or gliomas (astrocytomas or ependymomas), are comparatively rare, accounting for only about 10%. In children, they're low-grade astrocytomas.
Spinal cord tumors are rare compared with intracranial tumors (ratio of 1:4). They occur equally in men and women, with the exception of meningiomas, which occur mostly in women. Spinal cord tumors can occur anywhere along the length of the cord or its roots.

About prevalence and incidence statistics:
The term 'prevalence' of Kaposi's Sarcoma usually refers to the estimated population
of people who are managing Kaposi's Sarcoma at any given time.
The term 'incidence' of Kaposi's Sarcoma refers to the annual diagnosis rate,
or the number of new cases of Kaposi's Sarcoma diagnosed each year.
Hence, these two statistics types can differ:
a short-lived disease like flu can have high annual incidence but low prevalence,
but a life-long disease like diabetes has a low annual incidence but high prevalence.
