Notwithstanding the recent advances in the diagnostic field of Haematology, the morphological assessment of blood and bone marrow samples remains a cornerstone of the diagnosis and follow-up of haematological disorders. Examination of cell morphology provides the first orientation to the diagnosis, and directs clinicians towards the supplementary tests needed for a fully integrated diagnosis.
In the 4th revised edition of the World Health Organization (WHO) classification (2017), morphological assessment continues to play an indispensable role in diagnostics, and in many instances is the gold standard technique; for example in the identification and quantification of blasts, myelodysplasia, plasma cells or monocytic lineage cells.
The present Atlas from the Grupo Español de Citología Hematológica (GECH/ Spanish Group for Haematological Cytology) aims to be a free and dynamic source for consultation and learning addressed to consultants, trainees and other professionals with an interest in the field. The images have been collected from both the GECH website library and contributions by multiple regional Haematology and Cytology groups across Spain.
The Atlas is organised in 22 chapters that encompass both non-malignant and neoplastic disorders, the latter arranged as per the WHO classification 4th revised edition.
We hope that you find this Atlas useful and we kindly invite you to take part by sending your images through the GECH website.
