Primary Immune Thrombocytopenic Purpura (ITP) is an autoimmune hematological condition characterized by isolated thrombocytopenia and frequently presents with oral manifestations. However, reports of primary ITP in patients with Turner Syndrome (TS) are exceptionally rare, with few cases documented in the literature. Herein, we describe an unusual case of primary ITP with exuberant oral manifestations in a patient with TS.
A 29-year-old woman was referred to an oral diagnostic service with complaints of "blood blisters and gum bleeding" lasting 8 h. On extraoral physical examination, multiple petechiae were observed in the upper and lower limbs, in addition to hemorrhagic extravasation in the right ocular sclera (hyposphagma). On intraoral examination, multiple vesicles and blisters filled with blood were identified on the lower lip, back of the tongue, and buccal mucosa, along with spontaneous gingival bleeding and hemorrhagic petechiae on the palate. Laboratory tests revealed thrombocytopenia (5000/mm), whereas the blood count showed normality in the red and white series. After excluding other etiological factors or associated diseases, the patient was diagnosed with severe ITP and began treatment with systemic corticosteroids in the intensive care unit, resulting in a successful increase in platelets. After a 2-year follow-up, the patient remains free of ITP recurrences.
Oral manifestations may be one of the first signs of ITP. Therefore, it is essential that dentists are familiar with the condition and, when faced with unusual oral bleeding, consider the possibility of a hematological disorder such as ITP, ensuring a correct and early diagnosis. Moreover, the presence of ITP can further exacerbate complications associated with TS. Therefore, rigorous follow-up of these patients is crucial, considering the high incidence of cardiovascular and autoimmune diseases and the reduced life expectancy of these patients.
原发免疫性血小板减少症(ITP)是一种以孤立性血小板减少为特征的自身免疫性血液病,常伴有口腔表现。然而,特纳综合征(TS)患者的原发 ITP 报告极为罕见,文献中仅有少数病例报道。在此,我们描述了一例 TS 患者伴发丰富口腔表现的不典型原发 ITP 病例。
一名 29 岁女性因“血疱和牙龈出血”8 小时就诊于口腔诊断科。体格检查时发现四肢有多处瘀点,右眼巩膜有出血性渗出(低眼压)。口腔检查发现下唇、舌背部和颊黏膜有多个水疱和血疱,牙龈自发性出血和腭部出血性瘀点。实验室检查显示血小板减少症(5000/mm),而血常规显示红系和白系正常。在排除其他病因或相关疾病后,患者被诊断为重症 ITP,并在重症监护病房开始接受全身皮质类固醇治疗,成功地增加了血小板。2 年随访后,患者未复发 ITP。
口腔表现可能是 ITP 的首发征象之一。因此,牙医必须熟悉这种疾病,当遇到不寻常的口腔出血时,应考虑 ITP 等血液系统疾病的可能性,确保正确和早期诊断。此外,ITP 的存在可能会进一步加重与 TS 相关的并发症。因此,考虑到这些患者心血管疾病和自身免疫性疾病的高发率以及预期寿命缩短,对这些患者进行严格随访至关重要。
