Total body computed tomography (TBCT) and 68 Gallium DOTATATE PET\/CT localized a voluminous prostate tumour. A subsequent transurethral prostate biopsy documented a small cell carcinoma positive for ACTH and calcitonin and negative for prostatic specific antigen (PSA) at immunocytochemical study; serum prostatic specific antigen (PSA) was normal. Despite medical treatments, Cushing\u2019s syndrome was not controlled and the patient\u2019s clinical condition progressively worsened. Surgical resection was excluded; the patient underwent a cycle of chemotherapy followed by febrile neutropenia and fatal intestinal perforation. This case report describes a rare case of Cushing\u2019s syndrome and hypercalcitoninaemia due to a small cell carcinoma of the prostate, a rare tumour with very few therapeutic options and negative prognosis.<\/jats:p>","DOI":"10.1155\/2016\/6308058","type":"journal-article","created":{"date-parts":[[2016,12,1]],"date-time":"2016-12-01T16:09:59Z","timestamp":1480608599000},"page":"1-5","source":"Crossref","is-referenced-by-count":8,"title":["Unusual Cushing\u2019s Syndrome and Hypercalcitoninaemia due to a Small Cell Prostate Carcinoma"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8620-1900","authenticated-orcid":true,"given":"Antonio","family":"Balestrieri","sequence":"first","affiliation":[{"name":"Endocrinology and Diabetology Unit, \u201cM.
