Our interesting case deals with the clinical and morphological aspects of a chronic neutrophilic leukemia and the critical evaluation of differential diagnosis of leukemoid reaction in bone marrow biopsies.

Background. Myeloid sarcoma is an extramedullary neoplasm of immature myeloid cells. Our study reports a presentation of myeloid sarcoma which presented with severe leukemoid reaction as a secondary malignancy in a patient who was treated for acute lymphoblastic leukemia previously. The case emphasizes the difficulties in diagnosis of patients who do not have concomitant leukemia. Case Presenta...

The problem of the formation leukemoid reactions in cattle is considered. It noted that such changes morphological composition blood are most often characterized by a decrease quantitative content lymphocytes while increasing concentration microphages (neutrophils). With elimination cause caused manifestation reaction blood, peripheral restored to normal.

Leukemoid reaction describes an important leukocytosis (more than 50,000 white blood cells/mm3) with increased early neutrophil precursors. It is secondary to a physiologic stimulation of the bone marrow in most of the cases. It is called paraneoplastic when it is the consequence of cytokine storm induced by malignant processes. Many solid tumors have been associated with paraneoplastic leukocy...

Carbamazepine is widely used in the treatment of epilepsy, neuralgic pain, and bipolar affective disorders. Several adverse drug reactions have been described during the course of carbamazepine administration, including exanthemata and hematological reactions. Carbamazepine is one of the common drugs that have been implicated in the etiology of drug hypersensitivity syndrome. A 50-year-old male...

In this study, we describe a patient in whom tigecycline-induced drug fever and leukemoid reaction (LR) after 3 weeks of therapy for pneumonia.A 62-year-old man developed aspiration pneumonia on February 1, 2015. He had received multiple antibiotics at another hospital, but did not respond well. Disease rapidly progressed, and he was referred to our department on February 14. We adjusted the an...

Gastric tumors share many characteristics, making a definitive diagnosis challenging. Gastric adenocarcinomas represent 90% of malignant stomach tumors, meanwhile the frequency of gastric lymphoma range between 1-5% of all gastric cancers. Gastric carcinoma bears resemblance with particular forms of non-Hodgkin's lymphoma of the stomach, not only in morphological presentation, but also in clini...
