Context.—Lung tumors are histologically heterogeneous, but classification of lung
carcinoma has prognostic impact and increasingly, specific molecular correlates. Objective …

Pulmonary adenocarcinoma is one of the most common types of lung cancer. Traditionally,
adenocarcinomas have been divided based on their degree of resemblance to their parent …

Context.—Sarcomatoid carcinoma of the lung is a subset of poorly differentiated non–small
cell lung cancers that are diagnostically challenging because they are uncommon, may …

Pleomorphic carcinoma of the lung is a member of sarcomatoid carcinoma family of tumors,
which also include spindle and giant cell carcinomas, as well as truly biphasic neoplasms …

We collected 75 primary pulmonary carcinomas with pleomorphic, sarcomatoid, or
sarcomatous elements to better define their clinical, histologic, and immunohistochemical …

Pulmonary adenocarcinoma is the most common, and the most diverse form of primary lung
carcinoma. The histological complexity of these tumours poses problems for pathologists …

BACKGROUND: Biphasic lung cancers with admixtures of adenocarcinoma and
sarcomatoid components but lacking true mesenchymal differentiation (sarcomatoid …

To address the premise that pulmonary “carcinosarcomas” and spindle-cell carcinomas are
part of a single clinicopathologic continuum, the authors studied 21 examples of such …

Pulmonary sarcomatoid carcinomas (PSCs) are currently defined as poorly differentiated
non-small-cell carcinomas containing a component with sarcoma or sarcoma-like (spindle …

Pulmonary sarcomatoid carcinoma includes a heterogenous group of tumors difficult to
diagnose and treat. We report the clinicopathological features of 86 such tumors, including …
