DESCRIPTION
|
Kaposi Sarcoma (KS) is a cancerous tumor of the connective tissue involving blood and lymphatic vessels.
KS is often associated with AIDS (Acquired Immune Deficiency Syndrome). When KS occurs
in the lungs, it is referred to as Pulmonary Kaposi Sarcoma (KS) or Kaposi’s sarcoma
with pulmonary involvement. Pulmonary KS grows as sheets of tumor tissue in the peribronchial
and perivascular interstitial spaces. Symptoms and signs of pulmonary KS include dyspnea
(difficulty breathing), fever, non-productive cough, and hemoptysis (coughing up blood).
Complications of pulmonary Kaposi sarcoma include respiratory failure caused by airway
obstruction, parenchymal involvement, pleural effusion, or pulmonary edema from lymphangitic
obstruction.
|
DIAGNOSTIC TESTING, PHYSICAL FINDINGS, AND ICD-9-CM/ICD-10-CM CODING
|
Diagnostic testing: Chest CT and MRI may show findings suggestive of pulmonary KS, but the definitive
diagnosis is obtained by bronchoscopy showing characteristic lesions. Transbronchial
biopsy or open lung biopsy may be necessary if findings on bronchoscopy are inconclusive.
Physical findings: Symptoms and signs of pulmonary KS include:
-
•
Dyspnea (difficulty breathing);
-
-
-
•
Hemoptysis (coughing up blood);
-
•
Respiratory failure caused by airway obstruction;
-
-
-
•
Pulmonary edema from lymphangitic obstruction.
ICD-9: 176.4
ICD-10: C46.50
|
PROGRESSION
|
Survival for pulmonary KS is variable (between 4 to 19 months) after it is first diagnosed.
Related deaths are usually due to upper airway obstruction or parenchymal destruction.
|
TREATMENT
|
Chemotherapy in combination with antiretroviral therapy is used to treat pulmonary
KS. Radiation therapy has also been used in cases where there is intolerance to chemotherapy.
Radiation is also used to treat symptomatic airway obstruction.
