Diagnosis of Kaposi’s sarcoma

Kaposi’s sarcoma on the skin is not considered fatal for the life but when this sarcoma appears on other areas of body then it may prove dangerous. The doctors start the diagnosis of Kaposi’s sarcoma from the   information of medical history so that they get the complete idea about the medical condition of the patient.  It is possible that the previous illnesses and sexual history may help the doctor to find out  the exact cause of Kaposi’s Sarcoma. After examining the medical history the doctors proceed with a physical examination. In this exam the doctors fully check up the area where the sign of this tumor has appeared first.

Just after the physical examination, the doctors start the actual process of Kaposi’s sarcoma Diagnosis.


In this test the doctors remove a small amount of tissue from the skin lesion. After removal this sample is checked by a pathologist in order to know whether the tumor has invaded in the skin or not. The purpose of this examination is to get an idea about the tumor i.e. whether it is cancerous or non-cancerous.  There are two different Biopsies that are used in the diagnosis process of Kaposi ’s sarcoma ;one is named as punch biopsy while other is termed as excisional biopsy.

Punch biopsy:

In this test the doctor removes a piece of tissue about one-sixth of an inch in diameter from the lesion.

Excisional biopsy:

When the skin lesion is small then the physician goes for this biopsy in which they removed the entire lesion.

Imaging Studies

These studies include:


A chest x-ray is taken by the physician to know more about the tumor of Kaposi.

Computed Tomography (CT) scan:

In this scanning process, the detailed images of affected area are taken through a computer linked with an x-ray machine.  The doctors completely check these images in order to determine the cause and extent of cancer.

Magnetic Resonance Imaging (MRI):

This is an alternative of CT scan and through this process the cross-sectional images are created with the mean of strong magnet connected to the computer.

The doctor may go for some other advanced imaging tests and procedures. If you are interested to get the detail of Kaposi’s Sarcoma then feel free to follow this link; what is Kaposi’s Sarcoma?
