It is categorized into two main histological groups: small cell lung carcinoma (SCLC, 15% of all lung cancers) and non-SCLC (NSCLC, 85% of all lung cancers). NSCLCs are generally subcategorized into adenocarcinoma, squamous cell carcinoma (SqCC), and large cell …

When samples are collected from your lung during a biopsy (or cytology procedure), they are studied by a doctor with special training, called a pathologist. After testing the samples, the pathologist creates a report that details what was found, which can then be used to …

Classification of lung carcinomas by histopathologic subtype provides important information about prognosis and is necessary for optimal treatment. (See "Overview of the initial treatment of advanced non-small cell lung cancer".)

The 4 major histologic types of lung cancer are squamous cell carcinoma, adenocarcinoma, small cell carcinoma, and large cell carcinoma. 6 These major types can be subclassified into more specific subtypes such as lepidic predominant subtype of adenocarcinoma or the basaloid variant of large cell carcinoma. 6 More detailed reviews of the patholo...

Lung adenocarcinoma is histologically heterogeneous and has 5 distinct histologic growth patterns: lepidic, acinar, papillary, micropapillary, and solid. To date, there is no consensus regarding the clinical utility of these patterns.

Histological classification is one of the fundamental elements to be considered for therapy choice. The multidisciplinary team in charge of the patient, must precisely define the histology of the disease.

We explore all variants of efficient models for different image resolutions for the classification of lung and colon histopathology images into five classes (colon adenocarcinoma, benign colon tissue, lung adenocarcinoma, lung benign, and lung squamous cell carcinomas).

Lung cancer can be diagnosed based on histologic biopsy or cytologic specimens. The 2015 World Health Organization Classification of Lung Tumors addressed the diagnosis of lung cancer in resection specimens and in small biopsies and cytology specimens.

At present, lung cancers are generally classified histologically by conventional light microscopy. Figure VI-1 shows examples of some of the common histological types of lung cancers.

The natural history of bronchogenic carcinoma suggests that many years pass while the cancer evolves from a pre-cancerous change in the bronchial mucosa, to undetectable microscopic cancer, to preclinical asymptomatic cancer and finally into a full symptomatic cancer, the phase of most lung malignancies in the tissue at diagnosis.
