Large-Cell Carcinoma
Large-cell carcinoma is usually peripheral, large, lobulated and/or well marginated, heterogeneously enhancing mass with central necrosis (central necrosis may be absent if size is small).

Chapter
Small-Cell Carcinoma
Small-cell carcinoma usually arises from the main or proximal lobar bronchi and is located centrally in vast majority of patients who present with hilar or mediastinal mass.

Chapter
Carcinoid Tumor
Bronchial obstruction can lead to atelectasis or recurrent pneumonia of the affected lung/lobe/segment. The iceberg sign refers to a small portion of the tumor visible within the bronchial lumen compared to bulk ...

Salivary Gland–Type Tumors
Primary salivary gland–type tumors of the lung are rare neoplasms that arise from the submucosal glands of central airways. Four histologic types are identified (two of which are extremely rare).

Chapter
Adenomas
Benign tumors of the lung which arise from the bronchial mucous glands and usually present as a solitary lung nodule.

Chapter
Squamous Cell Carcinoma
Endobronchial nodule with segmental, lobar, or total lung collapse (early presentation). The Golden S sign refers to central obstructive right hilar tumor with right upper lobe atelectasis, which may be due to SC...

Chapter
Small Airway Disease
Respiratory bronchiolitis and follicular bronchiolitis are characterzed by ill-defined centrilobular nodules, while mosaicism and air-trap** are the imaging hallmark of obliterative bronchiolitis.

Chapter
Large-Cell Neuroendocrine Carcinoma
Classified as a subtype of large-cell carcinoma, large-cell neuroendocrine carcinoma arises from Kulchitsky cells of the bronchus similar to other neuroendocrine tumors of the lung (sixth decade, smokers).

Chapter
Sarcomatoid Carcinoma
Rare subtype of poorly differentiated NSCLC (0.1–0.4%) with overall poor prognosis compared to other NSCLCs, which have a sarcoma-like histology characterized by spindled, pleomorphic cells.

Acute Lung Injury
Acute onset bilateral lung infiltrates on CXR and hypoxemia (ALI = pAO2/F1O2 ≤ 300 mm Hg to severe form ARDS = pAO2/F1O2 ≤ 200 mm Hg) without clinical evidence of left atrial hypertension (or PCWP <18 mm Hg).

Mycobacterial Infections
TB spreads by droplet infection from person to person (one active TB patient infects 10–15 others and >10 million new cases/year). Person-person spread of nontuberculos mycobacteria is rare.
