Cronkhite-Canada综合征(CCS)是在1955年(1)首先描述一种罕见综合征此后,400案件全世界已在文献中报道。该疾病的特征为弥漫性胃肠息肉病,指甲,脱发,皮肤色素沉着,腹泻,体重减轻和腹痛的萎缩性改变。(2)的病因学目前是未知的,但是自身免疫过程被怀疑。后处理是根据病史和体格检查,随后成像和胃镜活检证实胃肠道息肉病。治疗的目标侧重于病人和营养支持的对症处理。
克罗克希特-加拿大综合征(CCS)是一种罕见的疾病,其特征是存在弥散性胃肠息肉、指甲营养不良改变、脱发、皮肤色素沉着、腹泻、体重减轻和腹痛。自1955年该综合征首次被记录在案以来,全球仅报告了约400例。这里我们报告一例CCS在菲律宾体面的妇女。
M. N.是一个39岁的菲律宾女子肠道阿米巴病的病史,谁被称为肠胃病为上腹疼痛评估。她的症状开始呈现前两个月2周水样腹泻为此她与甲硝唑认为阿米巴病治疗。她报告腹泻的改善,但后来发展餐后上腹疼痛描述为本质尖锐,持续数小时。她否认有任何发烧,寒战,恶心,呕吐,吞咽困难,或吞咽疼痛。However, she did report decreasing appetite with early satiety and a 9 kg weight loss over one month. She was initially evaluated by her primary care physician, who prescribed famotidine for her epigastric pain as well as hydrochlorothiazide for new onset hypertension. Shortly after this visit, she noticed a significant amount of hair loss as well as hyperpigmentation of her palms and soles. She worked at a jewelry store and denied any substance abuse. Her family history was significant for one uncle who had colon cancer at an unknown age.
病人的生命体征未见明显异常。Her weight was 68 kg and her height was 1.6 meters. Her exam was significant for diffuse alopecia and dystrophic changes of her fingernails (see Figure
Her white blood cell count was 12.3 thousand cells/mL (normal range 4–11 thousand cells/mL) with an absolute eosinophil count of 233 cells/mL. Her hemoglobin was 15.2 gm/dL (normal range 12–16 gm/dL) and hematocrit was 44.5% (normal range 37–47%). Albumin was 3.2 gm/dL (normal range 3.3–4.8 gm/dL) and her aminotransferases were normal.

在结肠息肉透露间质水肿,腺体扩张腺瘤性变化。胃息肉活检显示与扩张的腺体增生性局灶性功能。有没有嗜酸粒细胞增多的迹象(见图
CCS是基于对她的症状,临床特点和息肉样病变内镜检查过程中发现的组织病理学组合诊断。获得了包括免疫球蛋白γ4(的IgG4)和Antineutrophilic胞质抗体(ANCAs)附加血液工作均在正常范围内。由于她的体重减轻和食欲不振,营养治疗全圆周营养(TPN)的形式启动。At one month followup, the patient reported a weight gain of 6 kg. She also reported improvement of her alopecia, nail dystrophy, and symptoms of diarrhea. TPN therapy was discontinued after 2 months when she reported a rash around the infusion site. Steroid therapy was discussed with the patient but was declined. At her last followup, 12 months after the initial diagnosis, she appeared to be in clinical remission. Repeat endoscopy after 12 months also showed significant improvement in the number of polyps seen.
克朗希特-加拿大综合征是一种罕见的全身性疾病,由克朗希特和加拿大于1955年首次报道[
CCS的病因目前还不清楚。到目前为止,没有强有力的证据表明家族易感性。有趣的是,例已经升高的抗核抗体(ANA)和IgG4水平相关[
CCS的症状可变化,但传统上它的特点是弥漫性胃肠息肉病,指甲,脱发,皮肤色素沉着,腹泻萎缩性改变,和体重减轻的存在。其他症状,如味觉减退和口干燥症也已在文献中描述[
目前还不清楚CCS的最佳治疗方法,部分原因是它的稀缺性。如我们的病人所见,旨在改善电解质、维生素和矿物质缺乏的营养支持很少能诱导完全缓解。事实上,目前的文献更倾向于基于营养支持和皮质类固醇的联合治疗[
CCS可引起许多并发症,其中最显著的是恶性肿瘤的发展。这可能高达15% [
早期研究表明,长期预后较差。一项研究报告55名患者的死亡率为55% [
