  Cecil Textbook of Medicine : />
Accordingly, monocytosis is often seen in patients with tuberculosis, syphilis, fungal infections, ulcerative and granulomatous colitis, and sarcoidosis (Table 163-6).
Mild monocytosis is common in patients with Hodgkin's disease and a variety of cancers.
High levels of monocytes in the blood are most often seen in patients with hematopoietic malignancies, including acute and chronic myelomonocytic leukemia, acute monocytic leukemia, and chronic myelogenous leukemia of the juvenile type.

 eMedicine - Leukocytosis : Article by Susumu Inoue, MD   (Site not responding. Last check: 2007-10-12)
From a practical point of view, leukocytosis traditionally is classified according to the component of white cells that is contributing to an increase in the total number of WBCs.
Therefore, leukocytosis may be caused by an increase in (1) neutrophil count (ie, neutrophilia), (2) lymphocyte count (ie, lymphocytosis), (3) monocyte count (ie, monocytosis), (4) eosinophilic granulocyte count (ie, eosinophilia), (5) basophilic granulocyte count (ie, basophilia), or (6) immature cells (eg, blasts).
Monocytosis: This is defined as a monocyte count exceeding the upper limit of the reference range of 0.95 X 19

 Diagnostic Edge&##151;February 2005 Case Studies
There was a leukocytosis with a neutrophilia and left shift, a lymphopenia and a monocytosis.
At the time of presentation, the leukogram (Table 3, Day 1) was characterized as a leukocytosis with a neutrophilia, a left shift, a lymphopenia and a monocytosis.
This leukogram was interpreted as indicative of active inflammation with superimposed stress (high circulating glucocorticoids) and potential tissue demand for macrophages (monocytosis) as might be seen with tissue necrosis.

Leukocytosis consisting of a mature neutrophilia with a left shift, monocytosis and increased fibrinogen.
The source of the inflammation was thought to be an in utero infection such as placentitis, which may also have been an inciting factor for the foals premature birth.

 Study Case: Pulmonary Infiltrates with Eosinophils (PIE)
Other causes for eosinophilia, such as adrenocortical insufficiency and neoplasia, are not likely since values on the biochemistry panel were within reference intervals, and abdominal and thoracic radiographs were not suggestive of a mass.
Monocytosis may occur with acute and chronic inflammatory disease; this finding is nonspecific.
The mature neutrophilia and a lymphocyte count at the lower end of the reference interval are most likely secondary to previous use of corticosteroids.

 Glossary: M - R
Monocytes are the most commonly misidentified leukocyte in blood smears, often being placed into the lymphocyte category.
Increased numbers of circulating monocytes (monocytosis) occur in chronic suppurative, pyogranulomatous, necrotic, malignant, hemolytic, hemorrhagic or immune-mediated diseases.
Monocytosis also occurs in dogs as a corticosteroid-induced response from stress, adrenal hyperfunction or exogenous corticosteroids.

It resembles the other members of MDS in that it consists of anemia, neutropenia, and thrombocytopenia, but it also resembles members of the myeloproliferative disorders with monocytosis, circulating blasts, and splenomegaly.
The differentiation from CML by the monocytosis and lack of the Philadelphia chromosome.
MDS is usually seen in people greater than 60 and is slightly more common in men.

Genetic abnormalities that affect the function of monocytes and macrophages and cause buildup of debris within the cells result in the lipid storage diseases (such as Gaucher's disease and Niemann-Pick disease (see Hereditary Metabolic Disorders: Gaucher's Disease).
An increased number of monocytes in the blood (monocytosis) occurs in response to chronic infections, in autoimmune disorders, in blood disorders, and in cancers.
A proliferation of macrophages in tissues can occur in response to infections, sarcoidosis (see Infiltrative Lung Diseases: Sarcoidosis), and Langerhans' cell granulomatosis (see Infiltrative Lung Diseases: Langerhans' Cell Granulomatosis).

Aside from agranulocytosis, the bone marrow and blood show a number of other abnormalities (including maturational arrest of neutrophil precursors at the promyelocyte stage, absolute monocytosis, eosinophilia and thrombocytosis).
The gamma globulin level (antibodies) in blood is low, further increasing the risk for infection.
