[Prepubertal gynecomastia at the debut of hereditary tumors predisposition syndrome (clinical case reports)].
Peutz-Jeghers Syndrome (Peutz-Jeghers Syndrome, PJS) refers to syndromes of hereditary tumor predisposition and is caused by pathological variants of the STK11 gene, leading to a defect in the synthesis of serine/threonine kinase 11 protein, which acts as a tumor suppressor.Clinical symptoms of the syndrome are combination of hamartomatous polyposis of the gastrointestinal tract and specific skin-mucosal hyperpigmentation. Also, this disease is characterized by a high risk of developing gastrointestinal and extra-intestinal tumors, including benign or malignant tumors of the reproductive system.One of the first signs of the disease in male patients may be prepubertal gynecomastia associated with large-cell calcifying Sertoli cells tumors expressing aromatase. In contrast to from pubertal gynecomastia, prepubertal is extremely rare, and it is often based on pathological causes. Early diagnosis of patients with pre-pubertal gynecomastia, including Peitz-Jaegers syndrome, defines the tactics of gynecomastia management and protocols for monitoring the development of other components of the disease in the future.This article describes two patients with pre-pubertal gynecomastia and Peitz-Jaegers syndrome with different molecular genetic defects: in one case associated with duplication of the STK11 gene site, in the other - with microdeletion of the short arm of chromosome 19 containing this gene.
期刊介绍:
Since 1955 the “Problems of Endocrinology” (or “Problemy Endocrinologii”) Journal publishes timely articles, balancing both clinical and experimental research, case reports, reviews and lectures on pressing problems of endocrinology. The Journal is aimed to the most topical issues of endocrinology: to chemical structure, biosynthesis and metabolism of hormones, the mechanism of their action at cellular and molecular level; pathogenesis and to clinic of the endocrine diseases, new methods of their diagnostics and treatment. The Journal: features original national and foreign research articles, reflecting world endocrinology development; issues thematic editions on specific areas; publishes chronicle of major international congress sessions and workshops on endocrinology, as well as state-of-the-art guidelines; is intended for scientists, endocrinologists diabetologists and specialists of allied trade, general practitioners, family physicians and pediatrics.
