African Lymphadenopathic Kaposi Sarcoma

African lymphadenopathic Kaposi sarcoma (ALKS) is a rare form of Kaposi sarcoma that is primarily found in sub-Saharan Africa. This disease is characterized by the development of multiple lymph node tumors, often in the neck, and is associated with a high mortality rate. While the exact cause of ALKS is not fully understood, there are several factors that have been identified as potential contributors.

Types

There are several different types of ALKS, each with its own unique characteristics and diagnostic criteria. Here is a breakdown of the different types of ALKS:

1. Classic ALKS: This is the most common type of ALKS and is typically seen in older men. It presents as enlarged lymph nodes in the neck, chest, and groin, and can also cause fever, night sweats, and weight loss.
2. Endemic ALKS: This type of ALKS is more commonly found in children and young adults in certain regions of Africa. It is characterized by enlarged lymph nodes, skin lesions, and often involves the gastrointestinal tract.
3. Epidemic ALKS: This subtype of ALKS is typically seen in patients who are HIV-positive. It presents as multiple skin lesions and can also involve the lymph nodes and internal organs.
4. Iatrogenic ALKS: This type of ALKS is a rare complication of immunosuppressive therapy, such as after an organ transplant. It typically presents as skin lesions and can also involve the lymph nodes and internal organs.
5. African Cutaneous Kaposi Sarcoma: This subtype of Kaposi Sarcoma is typically found in Africa and presents as lesions on the skin. It can also involve the lymph nodes and internal organs.
6. Transplant-Associated Kaposi Sarcoma: This type of Kaposi Sarcoma occurs in patients who have received an organ transplant and are taking immunosuppressive medications to prevent rejection of the new organ.

Causes

Diagnosis

Common diagnosis and tests for African lymphadenopathic Kaposi sarcoma

1. Clinical evaluation: A medical professional will evaluate the patient’s symptoms, medical history, and physical examination to determine if they have African lymphadenopathic Kaposi sarcoma. They will also check for signs of enlarged lymph nodes, skin lesions, and other possible indicators of the condition.
2. Biopsy: A biopsy involves taking a small sample of tissue from the affected lymph node to examine it under a microscope. This helps to confirm the diagnosis and determine the extent of the cancer.
3. Immunohistochemistry: Immunohistochemistry is a laboratory test that uses special antibodies to detect specific proteins in the tissue sample. It can help to distinguish between different types of cancer and identify the presence of KSHV.
4. Polymerase chain reaction (PCR) test: A PCR test is a laboratory test that detects the genetic material of KSHV in the tissue sample. It can help to confirm the diagnosis and monitor the progression of the disease.
5. Blood tests: Blood tests can help to detect certain proteins and enzymes that are associated with cancer. They can also indicate if there are any abnormalities in the patient’s blood cells, liver function, or kidney function.
6. X-rays: X-rays use radiation to create images of the inside of the body. They can help to detect if the cancer has spread to the lungs or other organs.
7. Computed tomography (CT) scan: A CT scan uses X-rays and computer technology to create detailed images of the inside of the body. It can help to detect if the cancer has spread to other areas and determine the extent of the disease.
8. Magnetic resonance imaging (MRI) scan: An MRI scan uses magnetic fields and radio waves to create detailed images of the inside of the body. It can help to detect if the cancer has spread to the brain or other organs.
9. Ultrasound: An ultrasound uses sound waves to create images of the inside of the body. It can help to detect if the cancer has spread to nearby organs and lymph nodes.
10. Positron emission tomography (PET) scan: A PET scan uses a small amount of radioactive material to create images of the body’s metabolic activity. It can help to detect if the cancer has spread to other areas of the body.
11. Fine-needle aspiration (FNA): Fine-needle aspiration involves using a thin needle to extract a small sample of cells from a lymph node or other affected area. The sample is then examined under a microscope to check for cancerous cells.
12. Excisional biopsy: An excisional biopsy involves surgically removing the entire lymph node or other affected area. This allows for a more detailed examination of the tissue and helps to determine the extent of the cancer.
13. Lymph node dissection: Lymph node dissection involves surgically removing a group of lymph nodes in the affected area. This is usually done if the cancer has spread to nearby lymph nodes and helps to determine the extent of the disease.
14. Chest X-ray: A chest X-ray can help to detect if the cancer has spread to the lungs.
15. Biopsy of skin lesions: If the patient has skin lesions associated with the cancer, a biopsy may be done to confirm the

Treatment

Nonpharmacological treatments for African lymphadenopathic Kaposi sarcoma that you should know about.

1. Chemotherapy: Chemotherapy is a common treatment for ALKS. It involves the use of drugs that kill cancer cells or stop them from growing. The drugs are usually given through an IV or taken orally.
