The variable clinical features of TS include short stature, gonadal failure, and skeletal dysplasia. The association with growth hormone (GH) deficiency or other hypopituitarism in TS is extremely rare, with only a few case reports published in the literature. Here, we report the first case of a patient with mosaic TS with complete GH deficiency and pituitary microadenoma, and we include the literature review. During the work-up of the patient for severe short stature, three GH provocation tests revealed peak GH levels of less than 5 ng\/mL, which was compatible with complete GH deficiency. Sella magnetic resonance imaging showed an 8 mm non-enhancing pituitary adenoma with mild superior displacement of the optic chiasm. Karyotyping revealed the presence of ring chromosome X and monosomy X (46,X,r(X)\/45,X\/46,X,psu dic r(X;X)), which indicated a mosaic TS. It is important to consider not only chromosome analyses in females with short stature, but also the possibility of the coexistence of complete GH deficiency accompanying pituitary lesions in TS. In conclusion, the present study reports the first case of GH deficiency and pituitary adenoma in a patient with rare mosaic TS, which extends the genotype\u2013phenotype spectrum for TS.<\/jats:p>","DOI":"10.3390\/diagnostics10100783","type":"journal-article","created":{"date-parts":[[2020,10,5]],"date-time":"2020-10-05T08:35:57Z","timestamp":1601886957000},"page":"783","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Coexistence of Growth Hormone Deficiency and Pituitary Microadenoma in a Child with Unique Mosaic Turner Syndrome: A Case Report and Literature Review"],"prefix":"10.3390","volume":"10","author":[{"given":"Eu Gene","family":"Park","sequence":"first","affiliation":[{"name":"Department of Pediatrics, Incheon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, 56, Dongsu-ro, Bupyeong-gu, Incheon 21431, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eun-Jung","family":"Kim","sequence":"additional","affiliation":[{"name":"Samsung Medical Center, Department of Laboratory Medicine and Genetics, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eun-Jee","family":"Kim","sequence":"additional","affiliation":[{"name":"Samsung Medical Center, Department of Laboratory Medicine and Genetics, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyun-Young","family":"Kim","sequence":"additional","affiliation":[{"name":"Samsung Medical Center, Department of Laboratory Medicine and Genetics, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sun-Hee","family":"Kim","sequence":"additional","affiliation":[{"name":"Samsung Medical Center, Department of Laboratory Medicine and Genetics, Sungkyunkwan University School of Medicine, 81 Irwon-ro, Gangnam-gu, Seoul 06351, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4731-3701","authenticated-orcid":false,"given":"Aram","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, 29 Saemunan-ro, Jongno-gu, Seoul 03181, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1227","DOI":"10.1056\/NEJMra030360","article-title":"Turner\u2019s syndrome","volume":"351","author":"Sybert","year":"2004","journal-title":"N.
