The article presents a rare case of bone marrow metastasis of the spleen angiosarcoma. The observation is of particular interest due to the fact that secondary bone marrow damage in angiosarcoma in the vast majority of cases is due by primary tumor growth in the spleen. Clinically, such cases may resemble the course of blood diseases with hematological disorders and splenomegaly. Patients come into the field of view of a hematologist, and the final diagnosis is unexpected to the attending physician. Detection of angiosarcoma growth in a bone marrow trephine biopsy during morphological examination can be a rare finding for a pathologist. In this regard, the presented case is of interest not only for pathologists, but also for doctors of clinical specialties.
