Keratinizing Ameloblastoma In A 9-Month-Old Llama (Lama Glama), Karyn E. Bird, Jill E. Parker, Claire B. Andreasen, Barbara J. Watrous, Jerry R. Heidel

A 9-month-old male llama (Lama glama) was presented because of a rapidly growing mass on the right side of the face. Radiographs revealed a marked expansion of the right caudal face region with bone lysis involving the maxilla and the nasal, lacrimal, zygomatic, and palatine bones. Cytologically, the mass consisted of atypical round to polygonal cells with round nuclei and basophilic cytoplasms that formed acini and rows. Histologically, the mass consisted of anastomosing cords and sheets of neoplastic odontogenic epithelial cells embedded in a loose fibrovascular connective tissue. Single layers of peripheral, polarized, palisading, columnar epithelial cells were seen at …

Fifty clinically healthy llamas, 0.5–13 years of age (22 intact males, 10 neutered males, 18 females), with no biochemical evidence of liver disease or hematologic abnormalities, were selected to establish serum bile acid reference intervals. Serum samples submitted to the clinical pathology laboratory were analyzed using a colorimetric enzymatic assay to establish bile acid reference intervals. A nonparametric distribution of llama bile acid concentrations was 1–23 mmol/liter for llamas .1 year of age and 10–44 mmol/liter for llamas #1 year of age. A significant difference was found between these 2 age groups. No correlation was detected between gender and bile …
Multicentric Malignant Lymphoma In A Pallid Bat, Claire B. Andreasen, Julie R. Dulmstra
Multicentric Malignant Lymphoma In A Pallid Bat, Claire B. Andreasen, Julie R. Dulmstra

A 2.5-year-old, female pallid bat (Antrozous pallidus) was captured in Oregon (USA) in 1990 and later died in 1992. At the time of death, abdominal distension due to ascites, splenomegaly, and hepatomegaly, and a cheek mass were noted. Based on histologic examination of these tissues, a diagnosis of multicentric lymphoma was made. Retroviral particles were not found on electron microscopic examination.

Sera of 19 male and female bowhead whales (Balaena mysticetus) collected near Barrow, Alaska (USA) between 30 August and 13 October 1992 were evaluated for 18 serum chemistry values. Male bowhead whales had significantly greater creatinine and sodium concentrations, and significantly lower glucose concentrations than females. Pregnant females had greater triglyceride levels than non-pregnant females. The mean concentrations of creatinine, blood urea nitrogen, alkaline phosphatase, total bilirubin, total protein, sodium, potassium, chloride, phosphorus, and calcium were similar to those previously reported from bowhead whales. High aspartate aminotransferase and creatine kinase levels were attributed to muscle damage associated with harpooning.
