背景:坏疽性脓皮病(PG)是一种病因不明的皮肤溃疡现象。大约一半的病例有相关的皮外表现或相关的全身性疾病。最常见的相关系统性疾病包括炎症性肠病(IBD)。恶性血液病,自身免疫性关节炎,和血管炎.这是关于溃疡性结肠炎(UC)的巨大PG的病例报告,这是非常罕见的。
方法:一名39岁的女性农民患有UC,在过去的3年中出现了多个疼痛性溃疡,侵蚀,渗出,右腿结皮一个月。皮肤检查显示弥漫性分布,多个,定义明确,右侧内侧小腿深化脓性溃疡,尺寸为6至20厘米,右侧外皮上有零星的蠕虫吃的溃疡,严重的渗出和侵蚀。溃疡表现出深深的边界破坏,颗粒状组织和底部黑色焦痂。右小腿和脚严重肿胀,限制移动。足背动脉脉搏良好,右小腿和脚的皮肤上有正常的感觉。实验室检查显示白细胞计数为11.8×109/L,血红蛋白为91g/L,血沉为82mm/h,未升高的降钙素原,血清C反应蛋白131.29mg/L,结核菌素皮肤试验阴性.肠镜检查显示UC的内镜证据。皮肤病变活检显示浅表侵蚀和疤痕。部分表皮增生,部分表皮萎缩和变薄,皮肤乳头轻度水肿。真皮的大部分中部和下部,显示密集的淋巴细胞,组织细胞,多核巨细胞,中性粒细胞浸润.根据临床表现诊断为PG合并UC,实验室检查和小肠镜检查结果。
方法:她每天两次局部应用聚维酮碘和康复新液,甲泼尼龙琥珀酸钠40mg,复方甘草酸苷60mg,每天1次静脉滴注,与沙利度胺50毫克,每日两次。UC用美沙拉嗪控制。
结果:3个月后,她需要多种疗法才能达到PG愈合。在1年随访期间未观察到PG复发。
结论:认识到PG的临床特征及其致病性质,确保及时管理是防止严重破坏和畸形的基础,和控制相关疾病是治疗的重要方面。联合治疗对于患有IBD的PG患者至关重要。
BACKGROUND: Pyoderma gangrenosum (PG) is a phenomenon of cutaneous ulceration with unknown etiology. About half the cases have associated extracutaneous manifestations or associated systemic diseases. The most commonly associated systemic disorders include inflammatory bowel disease (IBD), hematologic malignancies, autoimmune arthritis, and vasculitis. This is a
case report about giant PG with ulcerative colitis (UC), which is extremely rare.
METHODS: A 39-year-old female farmer with UC for the past 3 years presented with multiple painful ulcers, erosion, exudation, and crusting on the right leg for 1 month. A cutaneous examination showed diffusely distributed, multiple, well-defined, deep purulent ulcers on the right medial shank measuring 6 to 20 cm and sporadic worm-eaten ulceration on the right ectocnemial, with severe oozing and erosions. The ulcerations exhibited deep undermined borders, granulated tissue and a black eschar at the base. The right shank and feet were severely swollen, restricting movement. The arteria dorsalis pedis pulse was good, with normal sensation on the skin of the right shank and feet. Laboratory examinations showed a white cell count of 11.8 × 109/L, hemoglobin was 91 g/L, erythrocyte sedimentation rate was 82 mm/h, unelevated procalcitonin, serum C-reactive protein was 131.29 mg/L, and a negative tuberculin skin test. Enteroscopy demonstrated endoscopic evidence of UC. A skin lesion biopsy showed superficial erosion and scarring. Partial epidermal hyperplasia, partial epidermal atrophy and thinning, mild edema of the dermal papill. Most of the middle and lower part of the dermis, showed dense lymphocytes, histiocytes, multinucleated giant cells, and neutrophil infiltration. PG with UC was diagnosed based on clinical manifestations, laboratory examinations and enteroscopy results.
METHODS: She was treated with topical applications of povidone iodine and kangfuxin solution twice daily, methylprednisolone sodium succinate 40 mg and compound glycyrrhizin 60 mg via intravenous drip once a day, along with thalidomide 50 mg twice daily. The UC was controlled with mesalazine.
RESULTS: She required multiple therapies to achieve PG healing 3 months later. No PG recurrence was observed during the 1-year follow-up.
CONCLUSIONS: Recognizing the clinical features of PG and its pathogenic nature, ensuring timely management fundamental for preventing severe destruction and deformity, and control of associated diseases are important aspects of treatment. Combination therapy is essential for PG patients with IBD.
