Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) is the optimal method for sampling lesions of the pancreas. This procedure is being performed at increasing numbers of hospitals and therefore, more and more cellular pathology departments are having to process and report EUS-FNAB specimens. This article outlines the advantages of using tissue/cell block preparation to process these specimens. In particular, such preparation concentrates, conserves and preserves sampled material which is then available for a full array of further analyses. Tissue/cell block preparation also enables EUS-FNAB specimens to be assessed by a wider range of cellular pathologists. This article demonstrates how a tissue/cell block protocol permits the diagnosis of the full range of pancreatic pathologies sampled by EUS-FNAB. The protocol is identical for all these pathologies (including both solid and cystic lesions) and is simple at all stages of the specimen pathway, from collection to processing to assessment.
