Multifocal tumor of vascular origin in a patient of AIDS-
## Core Concept
The question pertains to a patient with AIDS (Acquired Immunodeficiency Syndrome) presenting with a multifocal tumor of vascular origin. This scenario suggests an immunocompromised state leading to a specific type of neoplasm. The key here is the association with AIDS and the vascular origin of the tumor.
## Why the Correct Answer is Right
Kaposi's sarcoma (KS) is a type of cancer that forms in the lining of blood and lymph vessels. It is one of the most common types of cancer in people with HIV/AIDS, making it a significant concern in immunocompromised patients. KS presents as multifocal lesions and is known for its vascular origin, arising from cells that line lymph or blood vessels. The human herpesvirus 8 (HHV-8) is strongly associated with KS, and the immunocompromised state of AIDS patients increases their susceptibility to this tumor.
## Why Each Wrong Option is Incorrect
- **Option A:** This option is not provided, but typically, incorrect options might include other types of tumors not specifically associated with AIDS or not of vascular origin.
- **Option B:** If this option suggested another type of tumor not specifically linked to vascular origin or AIDS, it would be incorrect.
- **Option C:** Similarly, if this option proposed a tumor type that doesn't match the description of being multifocal and of vascular origin in an AIDS patient, it would not be correct.
## Clinical Pearl / High-Yield Fact
A key clinical pearl is that Kaposi's sarcoma often presents with skin lesions but can also involve visceral organs. In patients with AIDS, the presence of such lesions should prompt a biopsy for diagnosis. The association of KS with HHV-8 and its occurrence in immunocompromised states is a high-yield fact for exams.
## Correct Answer Line
**Correct Answer: D. Kaposi's Sarcoma.**
