目的 回顾性分析支气管肺泡细胞癌(bronchioloalveolar carcinoma,BAC)临床特点,提高早期BAC的确诊率,减少误诊。方法 对2013年—2014年间在我院确诊的BAC病例5例的临床资料进行回顾性分析。结果 5例患者中男4例,女1例,年龄在50～73岁之间,在社区医院均曾误诊为肺炎,所有患者均在我院经支气管镜肺活检后确诊为BAC。结论 BAC是一种较为特殊的肺癌,临床上症状无特异性,极易误诊为普通肺炎。由于BAC预后差,误诊后果严重,对初诊为普通肺炎的患者经常规抗感染治疗后临床症状及影像学表现改善不明显时,应及时进行各项检查、明确诊断,以便有效改善患者预后。

Objective To elevate the clinical diagnosis of BAC (bronchioloalveolar carcinoma) so as to reduce misdiagnosis by using retrospective analyses. Methods Retrospective analyses were used to study the five BAC patients, who were diagnosed in our hospital from 2013 to 2014. Results 4 of 5 male, and 1 female, age between 50 and 73, were diagnosed as pneumonia. All of them were made a definite diagnosis as BAC after performing transbronchial lung biopsy. Conclusion BAC is an exceptional lung adenocarcinoma and there is no specific clinic symptom. BAC was easily misdiagnosed as common lung pneumonia. There will be serious consequences after misdiagnosis of BAC due to its poor prognosis. Those patients who were misdiagnosed as common lung disease, but there was no obvious improvement after accepting long anti-infective therapy and there was negatively detection of pathogenic bacteria in them, are needed to perform all other clinical examination to clarify a diagnosis, and to further improve the prognosis of the patients.

目的 探讨OAB与CP/CPPS的症状及诊断的重叠情况,为临床诊疗提供参考。方法 151例中青年男性患者入选为研究对象,按OAB及CP/CPPS的定义及诊断标准将其分为OAB组、CP/CPPS组及OAB+CP/CPPS组,并对OAB+CP/CPPS组进行诊断性治疗对研究对象进行明确诊断;根据年龄分为:18~25岁组、26~35岁组和36~49岁组,比较各年龄组患者OAB及CP/CPPS的重叠情况;对各组患者的临床症状进行分析比较,了解其重叠情况。结果 在151例研究对象中,可诊断为OAB、CP/CPPS、OAB+CP/CPPS的分别有62例(41.06%)、32例(21.19%)、57例(37.75%),因此OAB与CP/CPPS的诊断重叠率为37.75%,明显大于CP/CPPS患者的诊断率;各年龄组间诊断重叠率无差异(P>0.05);症状的重叠方面,OAB+CP/CPPS组有尿急、尿频、夜尿症、急迫性尿失禁、尿不尽感、排尿困难、泌尿生殖系疼痛和或不适症状的分别为57例(100.00%)、50例(87.72%)、21例(36.84%)、2例(3.51%)、12例(21.05%)、2例(3.51%)、57例(100.00%),其中,尿急、尿频及泌尿生殖系疼痛或不适症状的重叠率最高;OAB+CP/CPPS组经诊断性治疗后诊断为OAB患者约61.40%,而CP/CPPS患者为38.60%。结论 OAB与CP/CPPS两者间有相当高的重叠率且远高于CP/CPPS的诊断率,在OAB与CP/CPPS两者诊断重叠的患者中为OAB的可能性更大。

Objective To explore symptoms and diagnosis of overlap between OAB and CP/CPPS, providing reference for clinical treatment. Methods 151 cases of young men were enrolled in the study. According to the definition and diagnostic criteria of OAB and CP/CPPS, we divided the study subjects into OAB group, CP/CPPS group and OAB+CP/CPPS group. And OAB+CP/CPPS group would get a two-week diagnostic treatment to study a clear diagnosis. We also divided the subjects into 18-25 age group, 26-35 year-old age group and 36-49 group according to the age, comparing the overlap of OAB and CP/CPPS in different age groups. The symptoms of the subjects in each group were analyzed to compare and study the overlap. Results Among these 151 cases, 62 cases (41.06%) can be diagnosed as OAB, 32 cases (21.19%) as CP/CPPS, 57 cases (37.75%) as OAB+CP/CPPS. Therefore, OAB and CP/CPPS diagnostic overlap was 37.75%, significantly higher than the diagnosis of CP/CPPS patients; no significant difference (P>0.05) among all age groups diagnostic overlap rate; overlapping terms of symptoms, OAB + CP/CPPS group urgency, urinary frequency, nocturia, urgency incontinence, urine not the flu, difficulty urinating, or genitourinary pain and discomfort were 57 cases (100.00%), 50 cases (87.72%), 21 cases (36.84%), 2 cases (3.51%), 12 cases (21.05%), 2 cases (3.51%), 57 patients (100.00%), which overlap ratio urgency, frequency, and genitourinary pain or discomfort was high; OAB+CP/CPPS group after diagnosis diagnostic treatment of OAB patients was about 61.40%, while CP/CPPS patients was 38.60%. Conclusion There is high overlap rate between OAB and CP/CPPS, which is much higher than the diagnostic rate of CP/CPPS. It is likely to have an OAB when a patient is diagnosed as OAB or CP/CPPS at the same time.

目的 探讨子宫内膜微腺体癌的临床病理特征、诊断及鉴别诊断。方法 对1例首诊误诊为子宫颈微腺体增生的子宫内膜微腺体癌病例进行临床、病理组织学及免疫组织化学特征的观察及总结,同时进行相关文献复习。结果 本例患者年龄61岁,因绝经后阴道不规则流血1年就诊,B超提示子宫内膜不规则增厚,并行分段诊刮术,先后两次诊刮标本光镜下均见黏液性柱状上皮呈乳头状及网格状结构,细胞轻度异型,核分裂罕见,间质内大量中性粒细胞浸润伴腺上皮内“微脓肿”形成;免疫组化示:上皮成分P16弥漫强(+),CEA小灶(+),Vimentin弥漫(+),ER约90%(+,中-强),PR约90%(+,弱),Ki-67约3%(+),间质细胞CD10(+)、CD34(-)。结论 子宫内膜微腺体癌是一种极为罕见的子宫内膜黏液腺癌,其组织学形态与子宫颈良性病变微腺体增生十分相似,易于混淆,但通过免疫组化检查及详细地临床病史资料收集、分析,可以与其鉴别,从而做出正确地诊断。

Objective To investigate clinical and histopathological features, dignosis and differential diagnosis of the endometrial microglandular adenocarinoma (MGA). Methods The clinical and pathological features of microglandular adenocarinoma in a patient were observed. Immunohistochemical staining and literature review were also used. Results In the case, the age of patient was 61 years. Clinical manifestation was vaginal irregular bleeding for 1 year. Type-B ultrasound suggested endometrium was irregular thickening. Histologically, it was mainly composed of irregular shape, closely spaced small glands, and glandular cells was mild atypical. Mitosis was rarely observed. The endometrial stromata between gland were rare, but neutrophil were much observed with the formation of neutrophil microabscess in the glandular epithelium. Immunohistochemical study showed neoplastic cells were diffuse and strongly positivity for P16, diffuse positivity for vimentin, focally positive for CEA. ER and PR expression was found in approximately 90% tumor cells. The index of Ki-67 was about 3%. Interstitial cells were positivity for CD10, negativity for CD34. Conclusion The microglandular adenocarcinoma is a rare endometrial adenocarcinoma. It can be differentiated from cervical microglandular hyperplasia(MGH) and cervical mucinous adenocarcinoma by immunohistochemistry and morphological characteristics.

        儿童孤立性直肠溃疡综合征（SRUS）是一种较为罕见的慢性直肠疾病,儿童发病率低且缺乏明确统计学数据。该病主要表现为便血、排黏液便和排便不尽感,临床诊断较为困难,常易误诊为其他疾病。其发病机制尚不明确,可能与排便习惯异常、直肠黏膜异常、血管异常以及遗传易感性等多种因素有关,其中 CHEK2 基因的 p.H371Y 突变可能在发病机制中起关键作用。诊断需综合病史、体格检查以及排粪造影、超声内镜、肠镜检查与组织病理活检等多种辅助检查手段。治疗上目前尚无统一指南,主要包括改善饮食和排便习惯、生物反馈治疗、药物治疗、内镜下治疗和外科手术治疗等,但总体治疗难度较大且复发率较高。本文对儿童 SRUS 的流行病学、发病机制、临床表现、诊断和治疗等方面的研究进展进行综述,旨在提高临床医师对该病的诊疗水平,为未来进一步的研究提供参考依据。
