Drug treatment alone is not always sufficient to relieve community pain and discomfort, and over 70% of humans with multiple myeloma are treated with radiation therapy during the course of their disease (26,27). chez les individuals atteints de mylome multiple sont discuts. (Traduit par Docteur Andr Blouin) An 8-year-old, 48 kg, undamaged male rottweiler was referred to the Veterinary Teaching Hospital in the Western College of Veterinary Medicine for staging and treatment of a previously diagnosed intraoral plasma cell tumor associated Vaccarin with the remaining maxilla. The dog HSTF1 had been offered to the referring veterinarian 11 d earlier having a remaining third eyelid prolapse and left-sided facial swelling of 1-day time duration. The dog had been anorexic and lethargic for 2 d prior to referral, and multiple pores and skin masses had been mentioned by the client 3 d prior to referral. Case description Physical exam exposed more than 50 smooth cutaneous and subcutaneous nodules, ranging from 0.5 cm to 2.5 cm in diameter, located primarily within the ventral aspects of the thorax and belly and the medial aspect of the thighs (Number 1). More superficially located nodules were moveable relative to underlying cells, while deeper nodules were fixed. The skin was mobile on the deeper nodules. Open in a separate window Number 1 Multiple Vaccarin nodules composed of neoplastic plasma cells within the medial surface of the right thigh. Under general anesthesia, a 4.0-cm 4.7-cm, necrotic, intraoral mass, centered in the remaining top 4th premolar, was recognized (Number 2). Open in a separate window Number 2 Soft cells mass involving the remaining intraoral region having a stressed out central area and necrosis, loss of tooth 208, and lateral displacement of tooth 209. Results from a complete blood (cell) count (CBC), serum biochemical panel, and urinalysis were evaluated. In the CBC, there was a slight lymphopenia (0.980 109/L; laboratory reference interval, 1.2 to 5.0 109/L) and marked rouleaux. Abnormalities in the serum biochemical panel included hypercalcemia (serum total calcium 3.86 mmol/L; laboratory reference interval, 1.91 to 3.03 mmol/L), elevated urea and creatinine (urea 15.9 mmol/L; laboratory reference interval 3.5 to 11.4 mmol/L, creatinine 213 mol/L; laboratory reference interval 41 to 121 mol/L), hyperglobulinemia (globulins 75 g/L; laboratory reference interval 23 to 37 g/L), and hypoalbuminemia (albumin 25 g/L; laboratory reference interval 28 to 38 g/L). The urine specific gravity of a voided urine sample was 1.016. Ancillary diagnostic checks included that for free calcium on a heparinized blood sample, serum and urine protein electrophoresis, urine sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE), serum radial immunodiffusion assay, imaging studies (simple film radiography, ultrasonography, and computed tomography (CT)), fine-needle aspirates (FNAs) of a subcutaneous nodule within the medial aspect of the stifle and a splenic mass, cytological examination of a remaining humeral bone marrow aspirate and histopathological examination of a remaining ilial bone marrow core, and histopathological examination of 2 of the subcutaneous nodules. Free calcium was elevated (1.81 mmol/L; laboratory reference interval, 1.27 to 1 1.51 mmol/L). In the serum protein electrophoretogram (Titan Gel Serum Protein System; Helena Laboratories, Beaumont, Texas, USA), a narrow-based maximum was Vaccarin recognized in the -globulin region (48.0 g/L; laboratory reference interval, 13.0 to 17.0 g/L) (Number 3a). A similarly located but smaller peak was found in the urine protein electrophoretogram (Number 3b). A band within the 20C25 kDa range and high molecular excess weight bands Vaccarin (> 69 kDa) were recognized on urine SDS-PAGE. The serum immunoglobulin (Ig) A concentration by radial immunodiffusion was elevated (229 g/L; published reference interval, 0.2 to 1 1.5 g/L) (1). Open in a separate window Number 3 Serum and urine protein electrophoretograms from an 8-year-old rottweiler with multiple myeloma. Notice the monoclonal maximum in the beta portion in the serum electrophoretogram (remaining) and a small peak in a similar region in the urine electrophoretogram (ideal). Thoracic, abdominal, and pelvic radiographs exposed.
