==Overview==
Kaposi's sarcoma may be classified according to the clinical setting of the [[disease]] into five subtypes include Classic Kaposi's sarcoma, African [[cutaneous]] Kaposi's sarcoma, African [[Lymphadenopathy|lymphadenopathic]] Kaposi's sarcoma, [[Immunosuppression]]-associated Kaposi's sarcoma, and [[AIDS]]-associated Kaposi's sarcoma.
==Classification==
==Classification==
HHV-8 is responsible for all varieties of KS. Since Moritz Kaposi first described this malignant neoplasm, the disease has been reported in five separate clinical settings, with different presentations, [[epidemiology]], and prognoses<ref name="Andrews">James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. ISBN 0-7216-2921-0.</ref>{{Rp|599}}. All of these forms are infected with [[Kaposi's sarcoma-associated herpesvirus|KSHV]] and are different manifestations of the same disease but have differences in clinical aggressiveness, prognosis and treatment.

*[[Vascular]] sarcoma
* Common in Mediterranean [[elderly]] [[men]]
*Indolent [[clinical]] [[behavior]]
*Pigmented [[macular]]–[[Papule|papular]] lesions on [[mucocutaneous]] surface
*Typically appears as dark [[blue]] or purple

Overview

Kaposi's sarcoma may be classified according to the clinical setting of the disease into five subtypes include Classic Kaposi's sarcoma, African cutaneous Kaposi's sarcoma, African lymphadenopathic Kaposi's sarcoma, Immunosuppression-associated Kaposi's sarcoma, and AIDS-associated Kaposi's sarcoma.

Classification

Types Characteristics
Classic (Mediterranean) Kaposi's sarcoma [4][5][6][7]
Endemic African Kaposi's sarcoma [8] Common features
  • Usually seen in areas with high prevalence of HHV-8 such as sub-Saharan Africa, called, Kaposi’s sarcoma-associated herpesvirus (KSHV)
  • Seropositivity in Sub-Saharan Africa is >50%
  • If caused by an undiagnosed HIV infection, it can be treated by antiretroviral medications
  • If caused by infection other than HIV, it can be treated by radiotherapy or chemotherapy
  • The limitations of achieving an optimal and affordable therapeutic approach in sub-Saharan Africa is:
    • Resource-limited settings and infrastructure issues such as lack of trained personnel to administer chemotherapy and lack of infusion centers, and the inability to monitor blood work, a high rate of co-morbid tuberculosis
  • Oral agents such as etoposide may have the benefit of easing the administration
African cutaneous Kaposi's sarcoma
African lymphadenopathic Kaposi's sarcoma
Iatrogenic (transplant-related) Kaposi's sarcoma (immunosuppression-associated Kaposi's sarcoma)[9][10]


(Epidemic) AIDS-associated Kaposi's sarcoma[11][12]
