A 39 year old female with signs of hyperandrogenism, was diagnosed with congenital adrenal hyperplasia after a cortrosyn test. Abdominal tomography showed a nodular image in the right adrenal gland, measuring 1.9 × 3.1 cm, 26 UH. Screening for Cushing's syndrome and pheochromocytoma was negative. Due to the maternal family history of MEN2A, RET gene testing was performed (positive), and screening for medullary thyroid carcinoma (MTC) with calcitonin was <2 pg/mL. As the patient's father passed away due to complications of peptic ulcers and hailed from a region with high rates of MEN1, PTH and calcium levels were checked, confirming the diagnosis of primary hyperparathyroidism (pHPT). Genetic investigation for MEN1 was positive, and an MRI of the pituitary gland revealed a non-producing macroadenoma. Management of pHPT and total prophylactic thyroidectomy were recommended, with an expectant approach regarding the adrenal lesion. Histopathological examination of the thyroid revealed papillary microcarcinoma in the right lobe and parafollicular cell hyperplasia in two foci, with immunohistochemistry consistent with MTC.
There may be the coexistence of three rare and complex genetic syndromes in a single patient. Multiple endocrine neoplasia syndromes describe a group of heterogeneous diseases. Hyperparathyroidism is common among multiple endocrine neoplasia syndromes.
一名39岁有高雄激素血症体征的女性,在进行促肾上腺皮质激素试验后被诊断为先天性肾上腺增生。腹部断层扫描显示右肾上腺有一个结节影像,大小为1.9×3.1厘米,26 UH。库欣综合征和嗜铬细胞瘤筛查为阴性。由于其母系家族有MEN2A病史,进行了RET基因检测(结果为阳性),降钙素筛查甲状腺髓样癌(MTC)结果<2 pg/mL。因患者父亲因消化性溃疡并发症去世,且来自MEN1发病率高的地区,检测了甲状旁腺激素(PTH)和钙水平,确诊为原发性甲状旁腺功能亢进症(pHPT)。MEN1基因检测为阳性,垂体磁共振成像显示为无功能大腺瘤。建议对pHPT进行治疗并实施全预防性甲状腺切除术,对肾上腺病变采取观察等待的方法。甲状腺组织病理学检查显示右叶有微小乳头状癌,两个病灶有滤泡旁细胞增生,免疫组化结果符合MTC。
单一患者可能同时存在三种罕见且复杂的遗传综合征。多发性内分泌肿瘤综合征描述的是一组异质性疾病。甲状旁腺功能亢进症在多发性内分泌肿瘤综合征中很常见。
