Tumors beyond this size are considered as carcinoid tumors, either typical or atypical type. These are usually discovered incidentally in lobectomy or wedge biopsy specimens obtained for other reasons. The morphology is usually bland with uniform cells and round or oval nuclei. The chromatin is usually granular with “salt and pepper” pattern. There is nesting of the cells with peripheral palisading of the cells (Fig. 5). The stroma could be scant or could show sclerosis and even calcifications.
The latter requires enough viable cells to be informative, and 4–5 cores are better for this type of testing as the test is complex and still relatively expensive. Repeated touch imprints on every core are not required, and it usually results in shedding most of the cells on the slides with few cells left in the core especially with well-differentiated adenocarcinoma where the cells are very discohesive and sparse [4–6]. On sectioning these specimens, the protocol mentioned in the transbronchial biopsy section above should apply here too.

The key difference from UIP is the lack of fibroblastic foci and the lack of variegated pattern of fibrosis (Fig.
