General description

Anti-Cytokeratin 5 & 6 labels greater than 90% of Eptihelioid Mesotheliomas. Anti-Cytokeratin 5 & 6 stains the cytoplasm of such cells. Anti-TTF-1 stains the nuclei in the case of lung adenocarcinomas and is negative in nearly all mesotheliomas. When the differential diagnosis seeks to distinguish between mesothelioma and adenocarcinoma of the lung, the nuclear vs. Cytoplasmic staining pattern of this cocktail can be of significant value in making the diagnosis.

The immunohistochemical identification of thyroid transcription factor-1 (TTF-1) is regarded as the presence of a nuclear pattern of staining and is used to identify tumors of thyroid or pulmonary origin. Although there have been reports of cytoplasmic expression of TTF-1

Thyroid transcription factor 1 (TTF-1), a homeodomain-containing transcription factor, plays a pivotal role in lung development, cell growth, and differentiation processes. The current literature reports considerable variation in frequency of TTF-1 protein expression in human non-small cell lung cancer (NSCLC).

Until recently, the standard approach of most laboratories in distinguishing epithelioid pleural mesothelioma from metastatic adenocarcinoma has been a negative result from a panel of adenocarcinoma-associated antibodies. However, several "mesothelium-associated" antibodies have been proposed as useful in this situation, and

Metastatic carcinoma of unknown primary origin is a perplexing but common problem, accounting for up to 10% to 15% of all solid tumors at presentation. Many of these metastases presumably arise from primary lung carcinomas, but the morphologic features and
