摘要

甲状旁腺癌(PTC)通常是散发的;然而,它可以作为遗传综合征的一个组成部分。原发性甲状旁腺功能亢进(PHPT)患者中PTC的患病率约为1%。缺乏可靠的术前预测因素显著地使PTC的诊断复杂化。临床病程无特异性,多数病例由严重高钙血症决定。最终诊断只能根据浸润性组织病理学特征做出,而免疫组化分析(IHC)只能作为一种附加方法。鉴于men1相关PTC的罕见诊断是一个挑战。我们报告了两例PTC患者的临床病例,并证实了MEN1基因的杂合突变。上述病例说明了PTC形态学诊断的复杂性,MEN1突变患者临床表现的异质性,以及及时筛查确定MEN1综合征的其他组成部分和一线亲属中MEN1基因突变的必要性。

Parathyroid cancer (PTC) is usually sporadic; however, it could be presented as a component of hereditary syndromes. The prevalence of PTC among patients with primary hyperparathyroidism (PHPT) is about 1% cases. The lack of reliable preoperative predictors significantly complicates the diagnosis of PTC. The clinical course is non-specific and in most cases is determined by severe hypercalcemia. The final diagnosis can only be made on the basis of invasive histopathologic features, while an analysis immunohistochemical (IHC) one can be used only as an additional method. Given the rarity the diagnosis of MEN1-related PTC a challenge. We present two clinical cases of patients with PTC and a verified heterozygous mutation in the MEN1 gene. The described cases demonstrate the complexity of morphological diagnosis for PTC, the heterogeneity of clinical manifestations in patients with the MEN1 mutation, as well as the need for timely screening to identify other components of MEN1 syndrome and mutations of the MEN1 gene among first-line relatives.

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.
