目的 探讨胃嗜酸性肉芽肿的诊断、误诊原因和治疗方法。方法 对14例胃嗜酸性肉芽肿的临床资料进行回顾性分析。结果 全部病例均有上腹疼痛和返酸史； 伴溃疡形成11例，穿孔4例，上消化道出血3例； 术前行胃镜检查2例，X线钡餐透视检查6例，无1例获确诊； 其余病例亦全部误诊为胃溃疡或癌肿。结论 胃镜多部位取材，特别是在溃疡与周边粘膜移行处，采取挖掘式取材，能减少误诊率； 胃大部切除术是主要的治疗方法。
目的 分析黄色肉芽肿性胆囊炎（XGC）误诊为胆囊癌的原因，探讨XGC的诊断和治疗策略。方法 回顾性分析2012年我科收治的2例XGC误诊为胆囊癌患者的临床病理资料。结果 2例患者术前及术中均误诊为胆囊癌，均行胆囊切除＋肝脏Ⅳ、Ⅴ段切除＋胆道镜下胆总管探查术，其中1例还行肝门周围淋巴结清扫。术后病理回报均为XGC。2例患者术后均恢复良好，无手术并发症发生；均随访3个月，生活质量好。结论 临床上根据XGC的症状和影像学表现极易误诊为胆囊癌，建议术中冰冻病理明确诊断后选择合适的术式，防止盲目扩大手术范围，减少机体损伤和术后并发症的发生。
Objective To summarize the preliminary effectiveness of surgical treatment of Erdheim-Chester disease (ECD), so as to improve the understanding of the disease by orthopedic surgeons. Methods The clinical data of 9 patients with ECD between December 2012 and October 2017 were retrospectively analysed. There were 6 males and 3 females with an median age of 42 years (range, 8-61 years). The disease duration was 4-59 months (mean, 39 months). There were 2 cases of multiple lesions, including 1 case involving soft tissue of the buttocks and bilateral tibia, 1 case involving the sinus, skull base, and proximal right tibia; 7 cases with single lesion, including 3 cases of right femoral neck, 1 case of proximal right tibia, 1 case of right humerus, and 2 cases of ribs. Nine patients were diagnosed according to clinical manifestations, imaging examination, and pathological diagnosis. Four patients underwent needle biopsy before operation and 5 patients were diagnosed by postoperative pathology examination. Five cases underwent lesional scraping and internal fixation, 1 case underwent bone scraping and bone grafting, and 3 cases underwent lesion resection. One of the multiple lesions was treated with interferon and hormone. Results Nine patients underwent the surgery safely. There was no fever, wound exudation, infection, etc., and the incisions healed by first intention. All the patients were followed up 4-59 months with an average of 31.4 months. One patient with bilateral tibia and hip soft tissue involvement continued to receive medical treatment, and the tumor was controlled without significant increasing. The remaining 8 patients were examined for X-ray films at 3, 6, and 12 months after surgery, the bone has been fused and the steel plate and intramedullary nail were firmly fixed, and no tumor recurrence was observed. At 1 year after surgery, the pain symptoms of the patients improved and returned to normal life; 3 of them who involving the right femoral neck walked freely, and the quality of life improved significantly. Conclusion ECD patients can achieve the purpose of eliminating lesions and relieving pain after surgical treatment, and the surgical treatment has the advantages of quick relief of pain, improved quality of life, small side effects, and low economic cost when compared with medical treatment.
Objective To explore the clinical characteristics, diagnosis and treatment plan of pulmonary lymphomatoid granulomatosis in order to deepen the understanding of this disease. MethodsA case of pulmonary lymphomatoid granulomatosis complicated with tuberculosis and human immunodeficiency virus (HIV) infection was reported. Literature reviews were searched in PubMed database with "pulmonary, lung, lymphomatoid granulomatosis" as the key words, and in China Knowledge Network and Wanfang database with "lung, lymphomatoid granulomatosis" as the key words. The search time was from January 1, 2017 to December 31, 2021. ResultsThe patient was diagnosed as pulmonary tuberculosis at the beginning of the disease, and the lesion was obviously absorbed and improved after regular anti-tuberculosis treatment. Six months after anti-tuberculosis treatment, chest CT examination showed multiple new circular nodules in both lungs. Intensive anti-tuberculosis treatment did not improve, further lung biopsy, pathology revealed lymphomatoid granulomatosis, grade 2; During the period, HIV infection was proven, and the patient underwent anti-viral infection and re-examination of chest CT lung lesions significantly improved absorption. Literature reviews found 47 same patients, therefore totally 48 patients were analyzed, in which this former case was included. Among the 48 patients, 26 were male (54.2%) and 22 were female (45.8%), with a median age of 60 years old (4 to 87 years old). The most common symptoms were cough, fever and shortness of breath, some of them may be accompanied with fatigue, weight loss, night sweats and loss of appetite. 20.9% of the patients had rashes, mainly manifested as erythema or papules. 39.6% of the patients were accompanied by immune system related diseases or immunosuppressants; The most common manifestations of chest CT were multiple nodules or masses involving both lungs. The main way of diagnosis was surgical lung biopsy, or CT-guided lung puncture biopsy. The positive rate of bronchoscopy biopsy was low. The pathological grade was mainly grade 3 (56.3%). The treatment plan was mainly R-CHOP, with an effective rate of 71.4%. For patients considered drug-induced disease, it was necessary to stop using induced drugs first, and then combined chemotherapy if there was no improvement. For HIV-infected patients, highly active antiretroviral therapy should be given first, if there was no improvement, then took combined chemotherapy; Of the 48 patients, 41 patients had clear follow-up results with a median follow-up time of 12 months, of which 14 patients were dead (34.1%), and the others got better in different degrees. Conclusions Pulmonary lymphomatoid granulomatosis is a rare disease. Clinicians should improve their understanding of it in order to identify the disease early, and choose the appropriate treatment scheme to improve its prognosis.
