Abstract
Pheochromocytomas and ultimobranchial (C-cell) neoplasms were diagnosed at a high frequency in a family of Guernsey bulls. The incidence supported the hypothesis of autosomal dominant inheritance of the neoplasms. These two neoplasms also occur in man as multiple endocrine adenomatosis type 2, which has autosomal dominant inheritance.

Abstract
The plasma cortisol response to exogenous ACTH (ACTH stimulation test) was evaluated in 22 dogs with hyperadrenocorticism caused by adrenocortical neoplasia. The mean basal cortisol concentration (6.3 microgram/dl) was high, but 7 dogs had basal cortisol concentrations that were within normal range. Administration of exogenous ACTH increased the plasma cortisol concentrations in each dog. Normal post-ACTH cortisol concentrations were found in 9 (41%) of the 22 dogs; 13 (59%) had an exaggerated increase in cortisol concentrations after ACTH administration. In 9 of 13 dogs with carcinoma and in 4 of 9 with adenoma, the cortisol response was exaggerated. The mean post-ACTH cortisol concentration in the dogs with carcinoma was approximately 4 times that of the dogs with adenoma; the 7 dogs with the highest concentrations had carcinoma. Repeat studies were performed in 6 dogs 2 to 8 weeks after initial testing. In 5 of the 6 dogs, repeat testing yielded data of similar diagnostic significance. One dog, however, had an abnormally high post-ACTH cortisol concentration at initial evaluation, but had only a minimal response to ACTH administration, with a normal post-ACTH cortisol concentration, at time of resting. Although ACTH stimulation testing is useful in diagnosing hyperadrenocorticism, it can not reliably separate dogs with hyperfunction adrenocortical tumors from clinically normal dogs or from dogs with pituitary-dependent hyperadrenocorticism (bilateral adrenocortical hyperplasia).

Abstract
The plasma growth hormone response to the provocative agent, xylazine, was assessed in 4 dogs with spontaneous hyperadrenocorticism, before and after therapy. Before treatment of the hyperadrenocorticism, no significant increase in growth hormone concentration occurred in any of the dogs following the administration of xylazine. A significant increase in growth hormone concentrations following xylazine administration occurred in 2 of the 3 dogs with hypophysis (pituitary)-dependent hyperadrenocorticism after treatment with mitotane (o,p'-DDD) and in 1 dog after surgical removal of a hyperfunctional adrenal adenoma. Although the impaired growth hormone response persisted in 1 dog, the administration of xylazine was repeated in this animal after only 3 weeks of mitotane therapy; it is likely that growth hormone unresponsiveness would reverse if the hyperadrenocorticism were controlled for a longer period. These findings demonstrate that in dogs, as in persons, the excessive production of endogenous corticosteroids associated with either hypophysis-dependent hyperadrenocorticism or hyperfunctional adrenal tumor can induce suppression of growth hormone release which is reversible following treatment.

Abstract
Pheochromocytomas and adrenal medullary hyperplasia were investigated ultrastructurally and by assaying catecholamines in tissue and urine. Three of seven bulls had concomitant thyroid C-cell neoplasms and normal parathyroid glands. Pheochromocytomas were either bilateral or unilateral, and were composed of large chromaffin cells predominantly in the storage phase of the secretory cycle. Two pheochromocytomas were composed of cells with ultrastructural characteristics of the epinephrine-secreting type and contained round secretory granules of low electron density. The norepinephrine-secreting type of chromaffin cell predominated in one pheochromocytoma and had storage granules with an electron-dense, eccentric core and a wide submembranous space. Two pheochromocytomas were composed of a mixture of epinephrine- and norepinephrine-secreting cells. Adrenal medullary hyperplasia in four bulls consisted of multinodular or diffuse areas of hyperchromatic chromaffin cells that were non-encapsulated, and compressed adjacent cortical tissue. Tissue and urinary concentrations of norepinephrine were increased in bulls with adrenal medullary hyperplasia or pheochromocytoma, but urinary vanillylmandelic acid and unconjugated epinephrine levels were not different from those of control bulls with a normal adrenal medulla.

Abstract
Hypothalamic norepinephrine (NE) and dopamine content was studied in dogs with spontaneous and iatrogenic hypercortisolism and in untreated normal dogs. The concentration of NE in the hypothalamus was subnormal in 4 of 8 dogs with pituitary-dependent hyperadrenocorticism (PDH), whereas long-term administration of corticotropin or cortisone acetate did not result in low hypothalamic NE content. In dogs with hyperadrenocorticism due to adrenocortical tumor subnormal as well as normal and high hypothalamic NE levels were found. Hypothalamic as well as striatal dopamine content did not differ among groups of dogs with PDH, adrenocortical tumor, corticotropin treatment, cortisone treatment and in untreated normal dogs. The subnormal hypothalamic NE levels in dogs with PDH may be involved in the hypersecretion of ACTH found in this disease. The normal hypothalamic dopamine levels in dogs with PDH are not consistent with a dopaminergic-depletion as the cause of PDH.

Abstract
The incidence of spontaneous pheochromocytoma in rats varies with the strain, sex, age and diet of the animals. Treatment with growth hormone, estrogens, or radiation is associated with the occurrence of pheochromocytoma in the rat. Histological evidence and transplantation studies indicate that pheochromocytoma in rats possesses a low grade of malignancy. A transplantable radiation-induced pheochromocytoma model has been shown to be functionally active.

Abstract
Of 60,048 aging F344 rats, 28 had ganglioneuromas of the adrenal gland. The rats were between 58 and 122 weeks old; 25 of them between 93 and 122 weeks when the tumors were found. The neoplasms were composed of large or small typical ganglion cells with a large pale nucleus and a prominent, often eccentric, nucleolus. The ganglion cells usually were distributed throughout the medullary tumor and surrounded by various numbers of supporting cells, including Schwann's cell types, and capsular or satellite cells. Often there was no clear-cut border between ganglion cells and neoplastic pheochromocytes. Electron microscopy of re-embedded tissues showed neurosecretory granules and cytoplasmic areas with an extensive rough endoplasmic reticulum (Nissl substance) in the ganglion cells and axons. The Schwann's cells were surrounded by a basement membrane and formed long cytoplasmic extensions around the axons. Almost all ganglioneuromas were associated with neoplastic pheochromocytes which usually were located at the edge of the tumors.

Abstract
The age-related incidences and types of spontaneous tumors were studied in 320 male and 354 female Wistar-Imamichi rats reared up to 130 weeks of age. The tumor incidence increased abruptly between 53 and 78 weeks of age, and 170 males and 269 females were shown to bear tumors during the observation period. Multiple tumors occurred in 62 males and 115 females. Most common were hypophyseal (male 69: female 224), mammary gland (29:99), testicular (74:0) and adrenal gland (26:21) tumors. The incidences of hypophyseal and testicular tumors increased with age. Tumors occurred in later stages of the observation period in the ovary, uterus and vagina (0:27), thyroid and parathyroid (13:12), skin (8:8), spleen and lymph nodes (8:7), pancreas (9:5), liver (3:7), lung (3:3), thymus (1:4), omentum and mesenterium (2:3), stomach and intestine (2:2), kidney and urinary bladder (1:2), right femur (0:1), and brain (0:1).

Abstract
Spontaneous endocrine tumors were found in 81 of 100 Sprague-Dawley rats (42 males and 39 females) which survived for more than 2 years. Most of these tumors were medullary carcinomas of the thyroid, followed by tumors of the anterior pituitary gland, pheochromocytomas and cortical adenomas of the adrenal gland, and islet cell tumors of the pancreas. Multiple occurrence of these tumors was frequently observed. This study describes the morphology of these spontaneous endocrine tumors.

Abstract
The outer medullary (juxtacortical) zone of a normal equine adrenal gland had columnar chromaffin-positive cells arranged with their long axes perpendicular to fine vascular channels. The deeper medullary regions were composed of smaller irregularly round to polygonal chromaffin positive cells in small packets. Both cell types contained two types of membrane-bound cytoplasmic secretory granules. Osmiophilic granules with a homogeneous core, crenated membrane and narrow submembranous halo predominated in the columnar juxtacortical cells. The rounder, central medullary cells contained predominantly electron dense granules with a wide irregular electron lucent space between an eccentric core and the granule membrane. In contrast, irrespective of cell type or zone, cells from a pheochromocytoma contained only one type of granule similar to that described for the juxtacortical region of the normal equine adrenal medulla. The tumor cells could be classified into three subtypes based on density of granule packing but the granules were morphologically similar in all tumor cells.

Abstract
An aged Boxer dog had 9 distinct primary tumors: chemodectoma, osteosarcoma, bronchiolo-alveolar adenocarcinoma, interstitial cell tumor, seminoma, basal cell tumor, fibropapilloma, adrenal cortical adenoma, and pancreatic adenoma. From this report, as well as from other studies, it is clear that Boxers have special susceptibilities to a variety of tumors. Analysis of clinical data on canine tumors indicated that the risk of Boxers for multiple tumors is only slightly higher than all tumors, indicating little or no specific predisposition for multiple tumors. In Boxers, however, certain tumor types occurred more frequently as multiple primary tumors than would be expected by chance.

Incidence of spontaneous tumors was examined in 77 male and 73 female SD-JCL rats reared throughout their lifespan of 5 to 36 months. Total tumor incidences were 60% and 95% for males and females, respectively. The sex difference was mostly attributable to a high incidence of mammary tumor in females. The pituitary tumor was found in 30% of males and 66% of females aged 5 to 36 months while islet cell tumor of the pancreas and thyroid tumor occurred later and the incidence of latter was particularly high in rats lived more than 2 years. Myeloid leukemia appeared to occur as early as 5 months of age.

Abstract
Gamma camera imaging of the adrenal glands was done in 8 dogs with hyperadrenocorticism and 4 normal dogs given intravenous injections of 131I-19-iodocholesterol. In normal dogs, both adrenal glands could be visualized separately, and there was no difficulty in distinguishing among the images of normal glands, hyperplastic glands, and functional adrenal tumors. In addition, gamma camera imaging enabled the correct surgical site to be selected for removal of adrenal tumors. Hyperadrenocorticism was diagnosed in 8 dogs by evaluation of urinary 17-hydroxycorticosteroid (OHCS) excretion rates, urinary 17-OHCS and plasma 11beta-OHCS RESPONSES TO DEXAMETHASONE SUPPRESSION OF ENDOGENOUS ADRENOCORTICOTROPIN (ACTH) secretion, and plasma 11beta-OHCS response to intravenous administration of ACTH. Base line 17-OHCS excretion increased in 5 of the 8 dogs. Plasma 11beta-OHCS concentrations were not decreased by dexamethasone administration in the 4 dogs subsequently found to have adrenal tumors; however, there was an exaggerated increase in plasma 11beta-OHCS concentration after administration of ACTH in 3 of the 4 dogs which had bilateral adrenocortical hyperplasia.

Abstract
This classification is arranged in two parts in order to take into account the different origins, structures, and functions of the cortex and medulla. The tabular classification is a simplified version of that suggested for adrenal tumours in man, and includes cortical adenoma and carcinoma, phaeochromocytoma, chemodectoma, neurofibroma, ganglioneuroma and ganglioneuroblastoma, and neuroblastoma. A detailed functional classification is not given, since the hormonal activity of many adrenal tumours in animals is less well known than it is in man. Of the tumour-like lesions listed, cortical hyperplasia is particularly important in several species.
