A variety of tumors can lead to bone marrow metastasis. This process is referred to as pitting. I'm praying that all goes well at your July 2 appointment. In addition to bone marrow aspiration, a bone marrow biopsy is essential here, as tumor cells are difficult to aspirate in the case of pronounced myelofibrosis and because the final classification of a myeloproliferative disease may only be possible in the light of histological findings and in many cases only after an extended molecular and immunohistochemical workup. Effect of splenectomy on teardrop-shaped erythrocytes in agnogenic myeloid metaplasia. As dacrocytes are associated with myelofibrosis, they are also theorized to be formed due to mechanically squeezing out from the bone marrow as a result of the infiltrative process. They can also be seen in patients with splenic abnormalities, vitamin B12 deficiency, and some other forms of anemia. They are not specific to a single entity.
