A chromophobic pituitary adenoma induced on BD IX-rats has been grafted on animals of the same strain. The transplanted tumour takes in 90-100%; it grows at a slow rate (in 7 months after grafting a weight of 7-20 g is attained). Tumour-bearing animals display gigantism and hypertrophy of adrenals; moreover, in 33% of cases, diabetes is observed. With non-diabetic animals, splenomegaly and marked leukocytosis are observed; immature white and red cells are present in the peripheral blood. Spontaneous regression of the tumour never occurs. After surgical removal, tumour regrowth and the formation of metastases are observed. Diabetes is characterised by pronounced hyperglycaemia, glucosuria, polyphagia and polydipsia. Histochemically, insulin cannot be detected in pancreas. Splenomegaly is never observed in diabetic animals. Transplanted adenoma frequently tends to stop growing. No recurrence is observable after extirpation. Spontaneous regression of the tumour sometimes occurs. Gigantism, hypertrophy of adrenals and diabetes are considered as consequences of growth hormone- and ACTH-secretion of the transplanted adenoma. At present the tumour is running in the 8th passage. It did not change its characteristics over a period of 5 years.

A 24 year old patient with epigastric pain, polyuria, polydipsia and hypercalcemia was admitted to the hospital. Besides the frequent causes of hypercalcemia such as primary hyperparathyroidism and malignancy-related hypercalcemia we had to consider sarcoidosis because of massive splenomegaly. The interstitial lung disease shown on x-ray films of the chest, the epithelioid granulomas in lung tissue and the increased ACE confirmed the diagnosis of sarcoidosis. Hypercalcemia is found in less than 5% of all cases with sarcoidosis. After treatment with steroids, diphosphonates and diuretics all symptoms and the hypercalcemia improved.

The course of naturally acquired infection with feline immunodeficiency virus was monitored in a cat over an 18-month period after diagnosis. The cat was admitted with diarrhea, poor body condition, a bite wound abscess, gingivitis, chronic fever, and splenomegaly. The cat's condition improved after splenectomy and remained stable for approximately 15 months, then began to deteriorate, as gingivitis, polyuria, polydipsia, pyrexia, multiple cutaneous masses, and hind limb paresis developed. The in vitro response of the cat's lymphocytes to mitogens was suppressed, and absolute lymphocyte counts were low. Spinal lymphosarcoma, disseminated mastocytoma, and presumptive diabetes mellitus were diagnosed after euthanasia. Decreased immune surveillance associated with feline immunodeficiency virus-related immunosuppression possibly played a role in the development of neoplastic disease in this cat.

A 13-yr-old ring-tailed lemur (Lemur catta) was evaluated for depression, anorexia, polyuria, and polydipsia. The lemur was in poor body condition and was anemic, hypoalbuminemic, and hyponatremic. Cytologic examination of aspirates of the spleen, liver, and bone marrow and histopathologic examination of liver and bone marrow biopsies revealed a disseminated round cell tumor. After euthanasia, necropsy revealed hepatomegaly, splenomegaly, and mesenteric lymphadenomegaly. Neoplastic cells were present within the spleen, liver, kidneys, multiple lymph nodes, bone marrow, lung, small intestine, pancreas, and testicle and were composed of large anaplastic round cells in a background of small well-differentiated lymphocytes. Immunohistochemical analysis revealed that the small well-differentiated lymphocytes labeled for the anti-human T-cell marker, CD3, and the large anaplastic round cells labeled with the anti-human B-cell marker, CD79a. On the basis of the immunohistochemical staining results and morphologic appearance, a diagnosis of a T-cell-rich B-cell lymphoma was made.

A 67-year-old trout fisherman presented with a six-week history of polyuria, polydipsia, dyspnoea on exertion and the development of subcutaneous extensor surface skin nodules. He was hypercalcaemic with acute renal impairment. Parathyroid hormone was suppressed and vitamin D levels were within normal limits. The patient had a past history of hypothyroidism, but thyroid replacement was adequate. Hypoadrenalism, myeloma and metastatic malignancy were excluded. Biopsy of a subcutaneous nodule revealed dermally based non-caseating granulomata, consistent with sarcoidosis. Serum angiotensin-converting enzyme was elevated, and computerized tomography scanning of the chest and abdomen revealed widespread lymphadenopathy with multiple lung nodules and splenomegaly. Prednisolone therapy produced rapid resolution of his skin lesions and normalization of his bone and renal biochemistry. The mechanism of hypercalcaemia in sarcoidosis is poorly understood but is thought to involve parathyroid hormone-independent 1-hydroxylation of 25-hydroxyvitamin D within sarcoid lesions. This process may be exacerbated by exposure to UV light and it is of interest that this patient developed symptoms after a period of intense trout fishing in the good weather of April and May 2007.
