Therefore, molecular testing of more than just the dominant nodule should be considered, especially if a smaller tumor has tall cell features.
We speculate that p120 plays an important role in directing this elegant process and that in the absence of p120, ameloblast cell-cell attachment and detachment becomes disorganized resulting in the loss of ameloblast organization as a tall columnar cell layer.
In this patient, the colon adenocarcinoma was positive for napsin A. Some thyroid carcinomas have also been reported to be positive for napsin A, which were all of the papillary type with tall cell morphology [3].

Similarly, although all studies associate the presence of a BRAF V600E mutation with papillary architecture, several studies have reported a higher prevalence of BRAF mutations in tumours classified as tall cell or columnar cell variants of PTC that are associated with more aggressive clinical behaviour and loss of responsiveness to radioiodine (Nikiforova et al, 2003; Begum et al, 2004).
However, PTCs comprise a morphologically heterogeneous group covering distinct variants that are classified on the basis of the occurrence of predominantly papillary structures (conventional type (PTC-CT)), a distinct growth pattern (follicular variant (PTC-FV) or cell type (e.g., tall cell variant (PTC-TCV)), among other features (DeLellis and Williams, 2004; LiVolsi and Baloch, 2004).
4G required tall cell towers to blast signals over long distances.
But they'll be tiny compared to the 100+ foot tall cell towers you're used to seeing.
