Few cases have been reported in the literature. We report the case of a salivary gland-type carcinoma of the nasopharynx diagnosed in a 70-year-old woman managed in department of radiotherapy at Hassan II University Hospital in Morocco. The patient received a total of 70 Gy of radiations, which were divided into 2 Gy per session during 7 weeks. Follow-up was performed regularly, including nasal endoscopic examination and nasopharyngeal CT. Evolution was marked by disease control after 12 months of follow-up. The aim of this work is to show the rarity of this entity, describe clinical, radiological and histological features and finally discuss the treatment management.展开更多

Even though these firearms are categorized as toys, injuries with these are quite common in children and adolescents. The most common reason for these types of injuries is accidents and negligence. In this case report we present a 17-year-old male, admitted to the emergency department with a 5 mm incision below his left eye. In the CT imaging a pellet was seen lodged in the cribriform plate. It pierced through the ethmoid sinus. The patient was admitted to the inpatient clinic and managed conservatively with antibiotherapy. A review of literature was performed to find out the best strategy to reach an optimized outcome and evaluate probable complications.展开更多

文摘目的:探讨乳腺浸润性筛状癌(invasive cribriform carcinoma,ICC)的超声声像图表现及临床病理学特征,以提高对该疾病的认识及诊断水平。方法:收集2008年1月 2018年8月上海交通大学医学院附属国际和平妇幼保健院收治的21例经手术后病理学检查证实为乳腺ICC的患者,分析其超声声像图表现及临床病理学资料。结果:患者均为女性,发病年龄为33~78岁,中位年龄53岁,病灶均发生于单侧。42.9%(9/21)患者筛状结构达100%,23.8%(5/21)患者筛状结构为50%~99%,33.3%(7/21)患者筛状结构<50%;3例伴腋窝淋巴结转移。超声声像图表现:病灶内部均为低回声,5例内伴点状钙化,90%边界不清晰或欠清晰,95%形态不规则或欠规则,71.4%内部和(或)周边可测及血流信号。95.2%(20/21)患者超声诊断为乳腺影像报告和数据系统(breast imaging reporting and data system,BI-RADS)4A类及以上,1例诊断为BI-RADS 3类。结论:通过掌握乳腺ICC的超声表现及临床病理学特点,有望提高对该疾病的认识及诊断水平。
