“…To the authors' knowledge, there are 11 previously reported cases of spontaneous pituitary tumors in nonhuman primates in literature. 3,14,[16][17][18]20,23,26,36,37,41 Of the reported cases, 7 were in Old World monkeys and 4 were in New World monkeys (Table 1). The frequency of these spontaneous neoplasms is likely higher than the reported rate owing to demographic and diagnostic factors, and may be similar to the rates reported for humans or other mammalian species.…”

Abstract. Pituitary adenomas were identified in 14 of 491 (2.9%) cynomolgus macaques evaluated from 1994 to 2004. Cases included male (8) and female (6) cynomolgus macaques ranging from 18 to 32 years of age. Seven of the pituitary adenomas caused gross enlargement of the pituitary gland that was visible on postmortem examination, whereas the remaining 7 were multifocal microadenomas identified on histologic examination. A total of 35 adenomas were identified in the 14 macaques, 6 of which were being treated for diabetes mellitus. Mean (6 SD) pituitary weight was 0.31 6 0.42 g, compared with 0.07 6 0.02 g for 430 historical control animals (P , 0.0001). Immunohistochemical staining for follicle-stimulating hormone, luteinizing hormone, prolactin, human growth hormone, thyroid-stimulating hormone, and adrenocorticotropic hormone was applied to pituitary tissue from all cases. Immunostaining revealed 22 of 35 (62.9%) lactotroph adenomas, 5 of 35 (14.3%) plurihormonal cell adenomas, 3 of 35 (8.6%) corticotroph adenomas, 2 of 35 (5.7%) null cell adenomas, 1 of 35 (2.9%) somatotroph adenomas, 1 of 35 (2.9%) mixed corticotroph-somatotroph adenomas, 1 of 35 (2.9%) mixed lactotroph-corticotroph adenomas, 0 of 35 gonadotroph adenomas, and 0 of 35 thyrotroph adenomas. This study represents the first extensive retrospective case series performed to evaluate the histologic and immunohistochemical characteristics of pituitary adenomas in cynomolgus macaques. Our findings indicated that macaque pituitary adenomas frequently had mixed histologic appearance and hormone expression, and that, similar to human pituitary adenomas, prolactin-secreting neoplasms were the most prevalent type.

“…The most common causes of goitre in animals include a dietary deficiency or excess of iodine, goitrogenic toxins and a defective negative feedback control by the pituitary (Anderson and Capen, 1978). Hollander and Riddle (1946) described goitre in pigeons (Cohimba livid) which responded to treatment with potassium iodine.…”
