A unique example of a gingival salivary gland choristoma together with a gingival cyst is described in a human autopsy specimen of periodontal tissues. A choristoma is a tumor-like growth which is derived from primordial cells which have been displaced from their original tissue or organ. Only 6 other examples of the gingival salivary gland choristoma have been described in the world literature. 相似文献

婴儿先天性胆总管囊肿16例诊治分析 总被引:6,自引:0,他引:6
1985 ̄1994年作者单位共收治小儿先天性胆总管囊肿105例,其中年龄小于12个月者16例,占15.2%,本病临床表现不典型,易延误诊治,超声检查可在产前检出本病,作者认为对于待续性黄疸的婴儿,保守治疗不宜时间过长,应积极手术探查。 相似文献

Mesenteric cyst is one of the rarest abdominal tumours, with approximately 820 cases reported since 1507. The incidence varies from 1 per 100000 to 250000 admissions. The lack of characteristic clinical features and radiological signs may present great diagnostic difficulties. The cyst may present in one of three ways: (i) non-specific abdominal features; (ii) an incidental finding; or (iii) an acute abdomen. Abdominal pain is the major presenting symptom. Abdominal mass is found in more than 50% of cases and 40% of cases are discovered incidentally. More than one aetiological mechanism is probably involved in the development of mesenteric cysts. Mesenteric cysts have been reported from the duodenum to the rectal mesentery but are most commonly located in the ileal mesentery. Malignant cysts occur in less than 3% of cases. Enucleation of the cyst is the treatment of choice. Knowledge of these tumours is important due to the various complications associated with suboptimal surgical management. Two cases of mesenteric cysts are presented including a recurrent mesenteric cyst in a post-partum woman demonstrating the inferior technique of internal marsupialization. The association of mesenteric cyst with pregnancy is discussed. 相似文献

本资料对93例不同性质的卵巢肿瘤细胞DNA及RNA含量进行了定量研究,其中50例良性、43例恶性。并对患者进行1~5年的随访。结果是卵巢良性肿瘤的异倍率(假阳性)为44%,恶性肿瘤异倍率为86.0%。以“标准DI”及“标准RI”为指标判断卵巢肿瘤性质的准确率较以“异倍性”为高,且双指标同时应用高于任一单指标:对卵巢良恶性肿瘤的诊断准确率分别为90%和95.3%。提出“标准DI”和“标准RI”是判断卵巢肿瘤性质的理想指标。且DNA及RNA含量与卵巢癌预后有密切关系。 相似文献

卵巢肿瘤蒂扭转的CT诊断价值探讨(附12例报告) 总被引:2,自引:0,他引:2
目的:评价CT对卵巢肿瘤蒂扭转的诊断,探讨囊壁局限性增厚对卵巢肿瘤蒂扭转的诊断价值。方法:对12例卵巢肿瘤蒂扭转的CT征象作回顾性分析,对卵巢肿瘤蒂扭转囊壁局限性增厚CT表现与文献报道的B超特征性表现双肿块声像图作对照分析。结果:本组12例病例中11例为卵巢囊性或者囊实性肿瘤,其中6例有局限性囊壁增厚,除此之外卵巢肿瘤蒂扭转还有其它许多CT征象,如卵巢肿瘤囊肿壁及囊肿内出血,附件输卵管增粗、显示,盆腔内积液,子宫位置偏位。结论:只要我们能密切结合临床,CT能对大多数卵巢肿瘤蒂扭转作出正确诊断。 相似文献

Introduction The authors report a case of interhemispheric ependymal cyst accompanied with agenesis of the corpus callosum in a fetus.
Discussion Routine ultrasound and subsequent magnetic resonance imaging of a 20-year-old woman at 33 weeks and 1 day of gestation detected
a large interhemispheric cystic lesion in the fetal cranial cavity. Caesarian section was carried out at 36 weeks because
of the progressive enlargement of the fetal head. The cyst was multiloculated and a cyst peritoneal shunt placement resulted
in collapse of the drained cyst components followed by enlargement of others. After wrack-a-mole-like shunt revisions, open
surgery was performed at the age of 2 years. Cyst walls were fenestrated and the cavities were communicated with each other
and eventually with the lateral ventricle. Pathological diagnosis of the cyst wall was ependymal cyst. The boy is now 3 years
old, and growing without apparent developmental delay or recurrence. Current concept and management policy of the interhemispheric
cyst accompanied with agenesis of the corpus callosum is reviewed. 相似文献

TAKAHIRO YOSHIDA TETSUYA TAKAO AKIRA TSUJIMURA HIROHIKO TOMITA KATSUYUKI AOZASA AKIHIKO OKUYAMA 《International journal of urology》2006,13(4):478-480
A 38-year-old Japanese man was referred to our outpatient clinic for treatment of infertility. Semen analysis showed azoospermia. Chromosome analysis revealed a 47XXY karyotype, and non-mosaic Klinefelter's syndrome (KFS) was diagnosed. Upon physical examination, the patient's right testicular volume was 30 mL and the left testicular volume was 3 mL. Laboratory tests showed normal levels of lactate dehydrogenase, alpha-fetoprotein, and human chorionic gonadotropin beta-subunit. The plasma luteinizing hormone and follicle-stimulating hormone levels were increased to 15.7 mIU/mL and 45.9 mIU/mL, respectively. The plasma testosterone was decreased to 0.25 ng/mL. Magnetic resonance imaging showed a right testicular mass of low-signal intensity on the T1-weighted image and of high-signal intensity on the T2-weighted image. Therefore, the final diagnosis was KFS with a right testicular tumor. Thus, a right high orchiectomy was performed. Histological examination revealed an epidermoid cyst of the right testis. Epidermoid cysts in cases of KFS are rare. To our knowledge, only seven cases, including ours, have been reported in the literature. 相似文献
