 AB    Several types of neoplastic conditions are included in the differential
       diagnosis of pneumonia. Bronchial obstruction with cancer can produce
       obstructive pneumonia that results in intractable infection.
       Bronchogenic carcinoma and metastatic cancer involving the airways may
       produce this clinical presentation. Bronchioloalveolar carcinoma is a
       relatively common form of primary lung cancer that characteristically
       presents as a chronic infiltrate associated with cough, hypoxemia,
       shortness of breath, and mucus hypersecretion. This cancer has two
       distinct histological types with markedly different prognosis. The
       mucinous variety is much more likely to be multicentric and rapidly
       progressive whereas the nonmucinous variety may be localized.
       Lymphoproliferative diseases may also present in an infiltrative
       appearance. Kaposi's sarcoma infiltrating the lungs, particularly
       associated with acquired immune deficiency syndrome, presents a
       diagnostic dilemma because of the high incidence of pulmonary infection
       in these patients.
