We report a 17-year-old female with chronic myeloid leukemia (CML) who developed monocytic crisis. She was diagnosed as chronic phase of Ph1-chromosome positive CML at 14 years old. Three years after the diagnosis of the disease, she was admitted to the hospital because of low grade fever, lethargy and marked splenomegaly. Small dose of Ara-C relieved her symptoms and splenomegaly. Six months later, however, a marked leukocytosis over 70,000/microliters were observed, and the peripheral blood smear disclosed that about 80% of the leukocytes were relatively mature monocytoid cells. Chromosomal analysis revealed additional abnormalities (double Ph1, +8, +9, +19). Lysozyme levels in serum and urine were high and NAP score was elevated. These monocytoid cells expressed receptors for IgG-Fc and C3, phagocytic activity, and monocytoid antigens which were determined by monoclonal antibodies (MY4, Mo2, OKM5). Cytochemically, almost all of monocytoid cells were positive for peroxidase and naphthol-ASD-chloroacetate esterase (CAE), but the monocytoid cells positive for non-specific esterase were limited. These data suggested that this case was monocytic crisis in CML with proliferation of CAE positive monocytoid cells. Among several types of blast crisis, monocytic crisis is extremely rare condition. The definite monocytic crisis demonstrated by this case may support the hypothesis that target cells of CML are pluripotent hematopoietic precursors.

A 3.5-year-old male Golden Retriever with lethargy, generalized lymphadenopathy, and hepatosplenomegaly was determined to have malignant histiocytosis, based on the morphologic appearance of neoplastic cells by light and electron microscopic examination, evidence of erythrophagocytosis, the presence of diffuse nonspecific esterase activity, and immunohistochemical demonstration of vimentin intermediate filaments. Because of the appearance of abundant iron stores in the bone marrow, serum was obtained for determination of iron, total iron binding capacity, and ferritin values. Serum ferritin concentrations were markedly increased. Measurement of serum ferritin concentrations may be useful in supporting a diagnosis of malignant histiocytosis, and the monitoring of serum ferritin concentrations may be useful for assessing treatment and regression of the disease.

A 3-yr-old bearded dragon (Acanthodraco vitticeps) presented with lethargy, a swollen right elbow joint, inability to move its rear limbs normally, and marked leukocytosis. The majority of leukocytes were an abnormal mononuclear lymphoid-type cell with a high nuclear to cytoplasmic ratio, a slightly blue cytoplasm, nuclei with coarsely granular chromatin, and some nuclear clefts. Acute leukemia of lymphoid or myeloid origin was tentatively diagnosed. The abnormal mononuclear leukocyte cell population stained positively for the myeloid cytochemical stains: peroxidase, chloroacetate esterase, and L1-calprotectin. The abnormal cell population of the peripheral blood did not stain with the lymphoid cytochemical stains: alpha-naphthyl butyrate esterase, CD3, and CD79a.

To qualify cellular events of possible pathophysiological significance in the parotid of ferret, tissue obtained post-mortem from mature animals of either sex was examined by light microscopical histochemistry for calcium, protein, amino acids, mucosubstances and hydrolases, and by neurohistology. Calcium was localised in acinar cells replete with granules containing protein, disulphides and usually carboxylated mucosubstances. Acid phosphatase activity was basally concentrated in the acinar cells. The granular luminal region of striated ductal cells showed protein, tryptophan, disulphides, neutral mucosubstances, and E600-sensitive esterase and Naphthol AS-D chloroacetate esterase activities, whereas their basal region showed acid phosphatase activity. Strong periluminal activity of acid phosphatase and E600-resistant esterase characterised the collecting ducts. Cholinesterase activity was associated with an extensive network of nerve fibres embracing parenchyma. Catecholamine fluorescence was not seen. beta-glucuronidase reactive macrophages abounded in the interstices. The results suggest that while the acini in the parotid of ferret secrete polyionic glycoproteins, shielded by calcium, the striated ducts secrete tryptophan-rich products comprising neutral glycoproteins and showing proteolytic activity. Innervation is of the cholinergic type and parenchymal lysosomal activity, possibly related to autophagy of stored secretory products and heterophagy of luminal material, is brisk. Macrophages contribute to maintaining the glandular microenvironment, wherein secretory activity appears to be lethargic.

An 18-year-old female alpaca was presented to the Colorado State University Veterinary Teaching Hospital for chronic ill thrift over a 1-year period. Six weeks previously, an infected left mandibular cheek tooth was removed by oral extraction. On physical examination the patient was cachectic, lethargic, and weak. Abnormalities on the CBC included neutropenia, thrombocytosis, and severe nonregenerative, macrocytic, hypochromic anemia. Dysplastic nucleated erythrocytes and micromegakaryocytes were observed on the peripheral blood smear. Neutrophils, bands, and metamyelocytes appeared markedly toxic. Numerous blasts containing variable numbers of fine azurophilic granules were also observed. Based on their morphology, the cells were interpreted to be progranulocytes and myeloblasts, and a presumptive diagnosis of acute myeloid leukemia (AML) was made. The blast cells accounted for 60% of the nucleated cell population on bone marrow aspirates, further supporting a diagnosis of AML with multilineage dysplasia. Post mortem examination showed infiltration of the neoplastic cells into spleen, liver, kidney, and lymph nodes. Based on histologic findings, the morphologic diagnoses were disseminated myeloid neoplasia, chronic regionally extensive tooth root abscess, and membranous glomerulonephritis. The neoplastic cells were CD172a-positive on flow cytometry, chloroacetate esterase-positive by cytochemistry, and myeloperoxidase-positive by immunohistochemistry, confirming myeloid origin. To our knowledge, this is the first case of AML with multilineage dysplasia in an alpaca, with only one other case of myelodysplasia described previously in this species.
