A 31-year-old woman developed gestational hypertension with psychiatric disturbances persistent to postpartum and was diagnosed with pheochromocytoma, for which adrenalectomy was performed. Histological findings showed mixed adrenocortical adenoma and pheochromocytoma. Double immunostaining of inhibin and INSM1 (insulinoma-associated protein 1) showed that the 2 tumor components had distinct functional properties. Exome analysis of peripheral leukocytes and tumor (singular, as anatomically it is only 1 mass) revealed a homozygous germline FGFR4-G388R variant. As a readout of the variant, serine phosphorylation of signal transducer and activator of transcription 3 (STAT3) was detected only in the nucleus of adrenocortical adenoma component but not in the pheochromocytoma component. No tyrosine phosphorylation of STAT3 was detected. We report a case of CMMT with the germline FGFR4-G388R variant. Although additional studies are required, our immunohistochemical analysis suggests that the variant may play a role in the development of the adrenocortical component within the pheochromocytoma, leading to CMMT.<\/jats:p>","DOI":"10.1210\/jendso\/bvaa101","type":"journal-article","created":{"date-parts":[[2020,7,21]],"date-time":"2020-07-21T02:46:41Z","timestamp":1595299601000},"source":"Crossref","is-referenced-by-count":11,"title":["Adrenal
