Ectopic growth hormone‐releasing hormone secretion by thymic carcinoid tumour

Abstract: The case of a 33-year-old-woman with Multiple Endocrine Neoplasia Type 1 (MEN1) syndrome and acromegaly due to ectopic growth hormone-releasing hormone (GHRH) secretion by a thymic carcinoid tumour is reported. Immunohistochemistry revealed positive immunoreactivity for GHRH, vasoactive intestinal polypeptide, somatostatin and alpha-subunit in the tumour cells. A previously undescribed new germ line mutation of the MEN1 protein gene was revealed.

“…They rarely oversecrete ACTH, calcitonin, or GH-releasing factor; similarly, they rarely oversecrete serotonin or histamine and rarely cause the carcinoid syndrome. However, GH production by a thymic carcinoid causing acromegaly has been reported 44 as also Cushing syndrome due to ACTH-producing thymic carcinoids. 45,46 The clinical course of carcinoid tumors is often indolent, but it can also be aggressive and resistant to therapy.…”

“…En el caso de nuestra paciente, aproximadamente la mitad del tumor quístico correspondía a tejido tiroideo. Algunos tumores carcinoides, principalmente de timo y próstata, se han reportado en pacientes con neoplasias endocrinas múltiples [7][8][9][10][11] . Nuestra paciente en el estudio imagenológico y bioquímico no evidenció neoplasia de tiroides, paratiroides, páncreas o suprarrenales.…”

“…El tratamiento ideal va dirigido a controlar el tumor primario que ocasiona el síndrome, no obstante los análogos de somatostatina representan una opción terapéutica útil en estos pacientes puesto que son capaces de mejorar la producción hormonal ectópica (54-70%) y la secreción hipofisaria de GH además de disminuir el tamaño tumoral 27 .…”
