TRABECULAR architecture is the 2nd salient cytomorphological pattern of a "Thyroid Follicular Neoplasm" after MICROFOLLICULAR. It's usually ill-developed and can be seen with or without association with capillary vessels.
ORANGE (keratinized squamous cells) in a pancreatic FNA not only adds a bright color to the PAP stained smear but also imparts a terribly bad prognosis to the tumor ("Adenosquamous Carcinoma" or an "Adenocarcinoma with Squamous differentiation").
