PG - 199-202 LID - 10.1515/jpem-2022-0488 [doi] AB - OBJECTIVES: Pituitary gigantism is a rare condition and it often has an identifiable genetic cause. In this article we report a case of a young girl with pituitary gigantism and two genetic changes. CASE PRESENTATION: A 15-year-old girl with primary amenorrhea was diagnosed with a growth hormone (GH) and prolactin (PRL)-producing tumor, needing surgery and medical treatment with octreotide in order to achieve disease control. The co-occurrence of an AIP mutation and a MEN1 variant of uncertain significance was demonstrated in this patient. The germline mutation involving AIP was inherited from her father who at the age of 55 was unaffected and the MEN1 variant was a de novo duplication of the region 11q13.1. The latter variant, not previously reported, is unlikely to be pathogenic. Nonetheless, screening for other components of multiple endocrine neoplasia type 1 (MEN1) was performed and proved negative. CONCLUSIONS: The rare co-occurrence of an AIP mutation and a MEN 1 variant of uncertain significance was demonstrated in this patient. CI - (c) 2022 Walter de Gruyter GmbH, Berlin/Boston.
