A 62-year-old Caucasian man presented with impotence. Clinically, he appeared acromegalic and subsequent investigations confirmed GH excess and hyperprolactinaemia. Magnetic resonance imaging (MRI) of pituitary revealed a large pituitary macroadenoma. He underwent trans-sphenoidal surgery and histology confirmed an adenoma with immunohistochemistry positive for ACTH, GH and prolactin. Acromegaly was not cured following surgery and inadequately controlled despite subsequent octreotide therapy. He underwent further debulking pituitary surgery, following which IGF1 levels improved but still high. This time adenoma cells showed immunohistochemistry positivity for ACTH only, following which subsequent investigations confirmed intermittent hypercortisolaemia compatible with pituitary Cushing's disease. We recommended radiotherapy, but in view of the pluripotential nature of the tumour, we proceeded with a trial of s.c. pasireotide therapy on the basis that it may control both his acromegaly and Cushing's disease. After 3 months of pasireotide therapy, his mean GH and IGF1 levels improved significantly, with improvement in his symptoms but intermittent hypercortisolaemia persists. His glycaemic control deteriorated requiring addition of new anti-diabetic medication. MRI imaging showed loss of contrast uptake within the tumour following pasireotide therapy but no change in size. We conclude that our patient has had a partial response to pasireotide therapy. Long-term follow-up studies are needed to establish its safety and efficacy in patients with acromegaly and\/or Cushing's disease.<\/jats:p>\n \n Learning points<\/jats:title>\n \n \n \n Plurihormonal pituitary adenomas are rare and unusual.<\/jats:p>\n <\/jats:list-item>\n \n Patients with pituitary adenomas co-secreting ACTH and GH are more likely to present with acromegaly because GH excess can mask hypercortisolaemia.<\/jats:p>\n <\/jats:list-item>\n \n Pasireotide holds potential where conventional somatostatin analogues are not effective in acromegaly due to higher affinity for somatostatin receptor subtypes 1, 2, 3 and 5.<\/jats:p>\n <\/jats:list-item>\n \n Significant deterioration in glycaemic control remains a concern in the use of pasireotide.<\/jats:p>\n <\/jats:list-item>\n \n Currently, long-term safety and efficacy of pasireotide in patients with acromegaly and\/or Cushing's disease are not fully clear.<\/jats:p>\n <\/jats:list-item>\n <\/jats:list>\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1530\/edm-13-0026","type":"journal-article","created":{"date-parts":[[2013,8,30]],"date-time":"2013-08-30T06:46:19Z","timestamp":1377845179000},"update-policy":"https:\/\/doi.org\/10.1530\/crossmarkpolicy-2","source":"Crossref","is-referenced-by-count":3,"title":["Pasireotide therapy in a rare and unusual case of plurihormonal pituitary macroadenoma"],"prefix":"10.1530","volume":"2013","author":[{"given":"Rajesh","family":"Rajendran","sequence":"first","affiliation":[{"name":"Department of Diabetes and Endocrinology, The Ipswich Hospital NHS Trust, Ipswich IP4 5PD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarita","family":"Naik","sequence":"additional","affiliation":[{"name":"1 Department of Diabetes and Endocrinology, Royal United Hospital Bath NHS Trust, Bath BA1 3NG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Derek D","family":"Sandeman","sequence":"additional","affiliation":[{"name":"2 Department of Diabetes and Endocrinology, University Hospital of Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Azraai B","family":"Nasruddin","sequence":"additional","affiliation":[{"name":"2 Department of Diabetes and Endocrinology, University Hospital of Southampton NHS Foundation Trust, Southampton SO16 6YD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"416","reference":[{"key":"ref31","doi-asserted-by":"crossref","first-page":"1002","DOI":"10.1007\/BF01411291","article-title":"A case of pituitary somatotroph adenoma with concomitant secretion of growth hormone, prolactin, and adrenocorticotropic hormone \u2013 an adenoma derived from primordial stem cell, studied by immunohistochemistry, in situ hybridization, and cell culture","volume":"138","year":"1996","journal-title":"Acta Neurochirurgica"},{"key":"ref51","doi-asserted-by":"crossref","first-page":"1102","DOI":"10.1097\/01.MP.0000030451.28828.00","article-title":"A case of Cushing's disease caused by pituitary adenoma producing adrenocorticotropic hormone and growth hormone concomitantly: aberrant expression of transcription factors NeuroD1 and Pit-1 as a proposed mechanism","volume":"15","year":"2002","journal-title":"Modern Pathology"},{"key":"ref81","doi-asserted-by":"crossref","first-page":"597","DOI":"10.1038\/nrd3788","article-title":"Pasireotide","volume":"11","year":"2012","journal-title":"Nature Reviews.
