| M6 | band form in the 6th stage of myelocyte maturation |

| myelocyte | A motile cell produced by and found in the bone marrow which develops intogranular leukocytes. (09 Oct 1997) |
|---|---|
| myelocyte A | The youngest form of myelocyte, characterised by only a few (not more than ten) cytoplasmic granules, which are most reliably demonstrated by means of staining with neutral red; the mitochondria are numerous, and resemble those of the myeloblast. (05 Mar 2000) |
| myelocyte B | The intermediate form of myelocyte, characterised by approximately 30 to 100 (or more) cytoplasmic granules scattered among the mitochondria; the latter are less numerous than in myelocyte's of the A stage, and they are frequently displaced toward the periphery of the cell. (05 Mar 2000) |
| myelocyte C | The most mature of the myelocyte's characterised by numerous cytoplasmic granules that are recognizable as neutrophilic, eosinophilic, and basophilic; with neutral red these are stained, respectively, red, bright yellow, and deep maroon; C myelocyte's are frequently larger than earlier forms; if the nucleus is indented, the myelocyte is maturing into a metamyelocyte. (05 Mar 2000) |
| parasitic eosinophilic lung disease | <radiology> All are metazoans (mostly nematodes), Ascaris, Strongyloides, Ancyclostoma, Schistosoma, tropical pulmonary eosinophilia, pulmonary larva migrans (12 Dec 1998) |
| chronic eosinophilic pneumonia | <radiology> Idiopathic, associated with allergies and desensitization, variant of Loeffler pneumonia, treatment: corticosteroids Findings: reverse pulmonary oedema pattern (= Loeffler's), areas of consolidation persists (days to weeks) see: eosinophilic lung disease (12 Dec 1998) |
| drug-induced eosinophilic lung disease | <radiology> Diffuse reticular pattern: nitrofurantoin, Loeffler-like pattern: penicillin, sulfonamides, ASA, para-ASA, imipramine, HCTZ, cromolyn sodium see: eosinophilic lung disease (12 Dec 1998) |
| eosinophilic | Staining readily with eosin dyes; denoting such cell or tissue elements. (05 Mar 2000) |
| eosinophilic cellulitis | <syndrome> Recurrent cellulitis followed by brawny edematous skin lesions, or a less acute presentation of papular, annular, or gyrate skin lesions which are sometimes urticarial; affected skin and subcutis are heavily infiltrated by eosinophils and histiocytes, with scattered small necrotic foci (flame figures) of varied aetiology; sometimes follows an arthropod bite. Synonym: eosinophilic cellulitis. (05 Mar 2000) |
| eosinophilic cystitis | Bladder inflammation with many eosinophils in urinary sediment as well as bladder wall. (05 Mar 2000) |
| eosinophilic endomyocardial disease | A restrictive cardiomyopathy associated with hyperproduction of eosinophiles and their cardiac infiltration, clinically characterised by diastolic and later systolic ventricular failure. (05 Mar 2000) |
| eosinophilic fasciitis | <pathology> A syndrome which is characterised by inflammation of the fascia and muscles of the extremities. Infiltrations of eosinophils are found in affected muscle tissue and fascia. The cause is unknown. Symptoms include tenderness and swelling of arms and legs, joint contractures, bone apins, muscle aches and muscle weakness. Some may complain of carpal tunnel syndrome symptoms with numbness and tingling in the hands. Diagnosis is made by tissue biopsy. Treatment includes systemic corticosteroids. The illness can last for 3 to 5 years and then ususally resolves. (27 Sep 1997) |
| eosinophilic gastritis | <radiology> Eosinophilic infiltration of mucosa, submucosa, and muscularis of small bowel with or without stomach, stomach (almost always limited to antrum): enlarged gastric rugae, cobblestone nodules, polyps (=mucosal type), rigid wall with narrowed antrum/pylorus, bulky inramural mass up to 9 cm (=muscular type), wet stomach, ulcers rare, may have ascites, small bowel (predominantly jejunum), thickening and distortion of folds (=mucosal type), effacement of mucosa and narrowing of lumen (=muscular type), prognosis: tendency to spontaneous remission, treatment: steroids; removal of sensitizing agent (12 Dec 1998) |
| eosinophilic gastroenteritis | <radiology> Eosinophilic infiltration of mucosa, submucosa, and muscularis of small bowel with or without stomach, stomach (almost always limited to antrum): enlarged gastric rugae, cobblestone nodules, polyps (=mucosal type), rigid wall with narrowed antrum/pylorus, bulky inramural mass up to 9 cm (=muscular type), wet stomach, ulcers rare, may have ascites, small bowel (predominantly jejunum), thickening and distortion of folds (=mucosal type), effacement of mucosa and narrowing of lumen (=muscular type), prognosis: tendency to spontaneous remission, treatment: steroids; removal of sensitizing agent (12 Dec 1998) |
| eosinophilic granuloma | <oncology, tumour> An immunologic disorder of unknown cause where there is proliferation of histiocytes (a type of cell in the immune system) in the bloodstream. The disorder is characterised by inflammation of the bronchioles and small pulmonary vessels that leads to fibrosis and destruction of alveolar cell walls. Cigarette smoking is considered a risk factor. Individuals with this disorder are also at increased risk for spontaneous pneumothorax. Symptoms include cough, chest pains, shortness of breath, fever, weight loss and malaise. Bronchoscopy with biopsy confirms the diagnosis. Childhood forms exist and cause more systemic symptoms and findings such as failure to thrive, weight loss, fevers, irritability, rash and bone pains. Treatment is with corticosteroids.
