256. A 39-year-old female presents with a cough and increasing shortness of breath. A chest x-ray is interpreted by the radiologist as showing a right lower lobe (RLL) pneumonia. No mass lesions are seen. The woman is treated with antibiotics, but her symptoms do not improve. On her return visit, the area of consolidation appears to be increased. Bronchoscopy is performed. No bronchial masses are seen, but a transbronchial biopsy is obtained in an area of mucosal erythema in the RLL. After the diagnosis is made, the RLL is removed and a section from this specimen reveals welldifferentiated mucus-secreting columnar epithelial cells that infiltrate from alveolus to alveolus. What is the correct diagnosis?
a. Bronchioloalveolar carcinoma
b. Carcinoid
c. Large cell carcinoma
d. Small cell carcinoma
e. Squamous cell carcinoma

such generalizations do not apply in all instances, coz low grade malignancies can be well differentiated!

because bronchioalveolar carcinoma appear as pneumonia in chest x ray and easily confused with pneumonia, also they are columnar and may secret mucin
