We are planning a research project on Ipath network and want to collect cases from the field of haematopathology and cytology. The material should be, either bone marrow smears, bone marrow histology, peripheral blood or fine needle biopsy (except Papanicolaou stains of prevention cytology). We would like to ask you to send these cases to the Haematopathology Forum, knowing that the images will be used for research projects. These cases should be uploaded anonymously. Age, gender, a short clinical report and possibly laboratory data, should be included in the description. At the beginning of the project, the specialized diagnose would be made, as usual on our platform. We would like to thank you in advance for your willingness to participate in this project. For questions about the planned project, please contact Dr. med. Peter Fritz, email: peter.fritz23@arcor.de
