A leukemoid reaction is defined as reactive leukocytosis exceeding 50,000/mm(3), with a significant increase in early neutrophil precursors, and can be a paraneoplastic manifestation of various malignant tumors. A 71-year-old male patient complained of decreased appetite, fatigue, and abdominal fullness. He had a palpable, firm liver, and laboratory investigations suggested leukemoid reaction. ...

PURPOSE To report a rare case of extreme leukocytosis and leukemoid reaction associated with lung sarcomatoid carcinoma (LSC) and increase people's awareness of the disease. PATIENTS AND METHODS A 58-year-old male patient was diagnosed with LSC; however, after the end of the second course of chemotherapy, his white blood cells increased gradually without fever or use of medications such as gr...

a 7 year-old male presented with recurrent fever, cough and respiratory distress for over last 2 years. based on extremely high eosinophil count, high immunoglobulin e, increase in eosinophilic precursors in bone marrow, and positive antigen test for wuchereria bancrofti, a diagnosis of tropical pulmonary eosinophilia with eosinophilic leukemoid reaction was made. complete recovery was achieved...

the hallmarks of leukocyte adhesion deficiency (lad) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. these molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. over las...

132 CMYK leukemoid reaction in bladder cancer. All six cases were associated with aggressive tumor cell growth and unfavorable clinical outcome. Only in one of the previously reported cases were fever and leukemoid reaction the presenting features of bladder cancer without any obvious metastases.[2] Two patients had rapid local recurrence six weeks after surgery.[3] Distant liver metastases at ...

A patient with metastatic soft tissue sarcoma presented with a leukemoid reaction. The elevated white blood cell count was due to an increase in bands and mature segmented neutrophils. The degree of granulocytosis correlated with the tumor burden. There was no evidence of superimposed infection and the degree of bone marrow involvement by metastatic tumor was minimal. A cell line derived from t...
