Clear cell adenocarcinoma (CCA) is a well-known major histologic type in renal cell carcinoma ().It is occasionally seen in non-renal primary sites such as ovary and lung ().CCA derives its name from the clear appearance of the cytoplasm and such changes in neoplastic cells are generally caused by fat, mucin or glycogen accumulation in the cytoplasm. Acinar - berry-shaped glands, smaller than lung acini.

There is no consensus on how grading of lung SCC should be done; however, a three tiered system is suggested in the CAP protocol, and some older data is suggestive that such a system for lung SCC can be predictive. Pulmonary salivary gland-type tumors (SGT) comprise a very small proportion of primary lung neoplasms. By definition, lung adenocarcinoma is a Neuroendocrine tumors of the lung (Lu-NETs) embrace a heterogeneous family of neoplasms classified into four histological variants, namely typical carcinoid (TC), atypical carcinoid (AC), large cell neuroendocrine carcinoma (LCNEC) and small cell lung carcinoma (SCLC).
