A RARE CASE REPORT OF GLOMUS TUMOUR OVER MARGIN OF LOWER LID OF LEFT EYE

Introduction: Glomus tumours are rare, benign tumours of vascular origin, arising from the glomus body. Glomus tumours are neoplasms of mesenchyme derived from glomus bodies. Glomus tumours present as a purple or pink vascular lesion that can be confused with a vascular neoplasm such as hemangioma. In this case we are reporting a rare presentation of glomus tumour over lower lid. A 10 year old female child presented with lesion over left lower Case Report: lid since 3 months which was painless and progressive. On examination a 0.3x0.3 cm subcutaneous pink non encapsulated mass is seen over medial canthus of left eye. Mass was excised and subjected to histopathological examination which confirmed the diagnosis of glomus cell tumour(glomangioma). Postoperative period was uneventful with no recurrence for last 6months. Conclusion: All excised eyelid lesions should undergo detailed Histopathological evaluation and glomus tumour should be considered as one of the differential diagnosis in patients presenting with eyelid mass

Clinicopathological significance of atypical squamous epithelium cells which cannot exclude high-grade squamous intraepithelial lesions in cervical cytology / 肿瘤研究与临床

Objective To investigate clinicopathological significance of atypical squamous epithelium cells which cannot exclude high grade squamous intraepithelial lesions (ASC-H) in the diagnosis of cervical diseases. Methods The results of age, high-risk human papillomavirus DNA (hrHPV DNA) and cervical biopsy in 496 patients with ASC-H from March 2012 to December 2015 in Shanxi Dayi Hospital were analyzed. Results Among 496 ASC-H cases, the proportion of the patients between 40 and 49 years old was the highest [30.8 ％ (153/496)]. HrHPV DNA was detected in 154 cases, and the positive rate was 79.2 ％(122/154), and the positive rate of patients at the age of 18 to 29 years old was the highest [84.2 ％ (16/19)]. The detection rate of cervical intraepithelial neoplasia (CIN) Ⅱand above lesions in 124 cases with cervical biopsy was 66.9 ％ (83/124), including 100 cases with hrHPV DNA positive (80.6 ％) and 24 cases with hrHPV DNA negative (19.4 ％). There were 71 cases (71.0 ％) of CINⅡ, CIN Ⅲ, early squamous carcinoma and squamous cell carcinomas in 100 hrHPV DNA positive patients with cervical biopsy. There were 12 cases (50.0 ％) of CINⅡ/Ⅲ changes in 24 hrHPV DNA negative patients with cervical biopsy, but none in early squamous carcinoma and squamous cell carcinomas was detected, and there was a significant difference between hrHPV DNA positive and negative patients (χ2=3.857, P< 0.05). The positive predictive value, negative predictive value, sensitivity and specificity of hrHPV DNA detection for diagnosis of CINⅡand above lesions were 85.5 ％, 29.3 ％, 71.0 ％ and 50.0 ％, respectively. Conclusions ASC-H strongly predicts CINⅡand above lesions in cervical cytology. The detection of hrHPV DNA has a high positive predictive value for CINⅡand above lesions.

Spindle cell carcinoma of the conjunctiva: A rare entity.

An 85‑year‑old male presented with painless bulging lesion over the cornea. Clinical history, diagnostic imaging studies, and histopathologic sections were evaluated. The patient clinically displayed an vascularized conjunctival lesion located at the superior bulbar conjunctiva with extension onto cornea covering 2/3 of his pupillary aperture superiorly. His visual acuity was counting fingers at 4 m. The patient underwent a total excision of the lesion including conjunctival and corneal parts. Histopathologic evaluation revealed spindle cell carcinoma which involves the whole conjunctival squamous epithelium with significant polarity loss, nuclear enlargement with hyperchromasia and pleomorphism, and mitotic activity. Diagnosis of spindle cell carcinoma is challenging because of overlapping histopathological features with other spindle cell tumors. The detailed pathologic examination is very important for the decision of proper treatment.

Quiste epidermoide del ventrículo lateral / Epidermoid cyst of the lateral ventricle

Los quistes epidermoides del ventrículo lateral son lesiones extremadamente infrecuentes originadas por la inclusión de elementos epiteliales al momento del cierre del tubo neural. Son tumores de lento crecimiento y se presentan clínicamente con síntomas inespecíficos. La Resonancia Magnética de encéfalo permite realizar un diagnóstico presuntivo, que se confirma por hallazgos característicos durante la cirugía. El diagnóstico de certeza es por la anatomía patológica en donde se observa un epitelio escamoso estratificado. Se presenta un caso de una mujer de 39 años operada por vía microquirúrgica con asistencia endoscópica.

Epidermoid cysts occurring within the lateral ventricles are uncommon lesions. These tumors are of developmental etiology, due to migration of epiblast inclusion at the time of neural tube occlussion of the neural tube. They are slow growing tumors and clinical presentation is nonspecific. Magnetic Resonance is suggestive of a cystic lesion, and is confirmed to be a epidermoid cyst at operation. Histopathology reveals typical stratified squamous epithelium. A case of a woman of 39 years old woman operated on with microsurgery and endoscopic assistance is presented..

A Case of Ileal Duplication Cyst Lined by Ciliated Columnar and Squamous Epithelium / 대한소화기학회지

Duplication is a rare congenital abnormality and may occur in any region of the gastrointestinal tract. A 19-year-old woman was admitted due to lower abdominal pain. Abdomino-pelvic CT scan showed a cystic mass interpreted as mesenteric cyst or duplication cyst. On the operation finding, it seemed to be arised from mesentery but attached to the ileum. Microscopically, the cystic wall was lined by non-keratinizing squamous, ciliated pseudostratified columnar epithelium, and ectopic gastric mucosa with two distinct muscular layers and a serosa. We report the first case of ileal duplication cyst lined by squamous and ciliated columnar epithelium in Korea.

Congenital Dermal Sinuses: An Clinical Analysis of 20 Cases

OBJECTIVE: Congenital dermal sinus is a rare congenital disease that results from the failure of the neuroectoderm to separate from the surface ectoderm during the process of neurulation, where there is communication between the skin and the deeper structures. Their pathogenesis, clinical course and treatment strategy are well known. We analyze our series and compare our results with other series. METHODS: Twenty patients were diagnosed as congenital dermal sinus and confirmed pathologically from October 1986 to July 2003 at our hospital. We studied the patients' clinical manifestations, radiological findings and pathological profiles. RESULTS: Seven cases were located in the suboccipital area and 13 cases were located in the spinal area. Interestingly, 4 of 13 spinal lesion cutaneous openings were located lower than the 3rd sacral body level. 8 of 20 lesions were terminated at neural structures, 4 of 20 lesions were terminated at the intradural portion and others terminated at the extradural portion. Nine anomalies were combined with the dermal sinus, including 4 lipomas, 2 Currarino's triad, 1 encephalocele, 1 myelomeningocele and 1 diastematomyelia. Eleven patients had dermoid tumors. CONCLUSION: Congenital Dermal Sinus must be surgically removed immediately if they are diagnosed. The surgical procedure of congenital dermal sinus is complete removal, but in some cases, complete removal is impossible. In those cases, we removed all epithelial tissues. We consider sacrococcygeal dimple almost invariably have no connection with intraspinal structures. But, if other cutaneous manifestations are combined with cutaneous pits, it can communicate with the sacrococcygeal dimple.

Cinética celular em lesöes pré-invasivas e invasivas do epitélio escamoso cervical: estudo morfológico e imunoistoquímico / Cellular kinetics in preinvasive and invasive lesions of cervical squamous epithelium: morphologic and immunohistochemical study

Avaliar quantitativamente a apoptose (morte celular programada) e a taxa de proliferaçäo celular no espectro das lesöes neoplásicas do colo uterino. Materiais e Métodos: Analisamos 81 biópsias cervicais previamente diagnosticadas na Divisäo de Patologia do Instituto Adolfo Lutz segundo a classificaçäo da OMS como sendo: neoplasia intraepitelial cervical de grau 1 NIC 1=20,NIC2=19,NIC3=23 e carcinoma de células escamosas (CCE)=19. Foi utilizado o método imunoistoquímico para detecçäo das células em proliferaçäo (MIB-1) e o método de TUNEL para a apoptose. As células foram contadas através de fotomicrografia digital, sendo que o número variou de 83 a 2975 média=1515,62) para MIB-1 e 315 a 3565 para apoptose (média=1273,24). Resultados: Houve um aumento progressivo nas taxas de proliferaçäo (por cento) com a severidade da lesäo (NIC 1=22,7;NIC 2=34,5;NIC 3=38,3;CCE=52,6P<0,0001). O mesmo foi obtido com as taxas de apoptose (por cento) (NIC 1=0,30;NIC 2=0,55;NIC 3=0,70;CCE=1,19p<0,0001) e o índice de renovaçäo celular (por cento) (NIC 1=23,0;NIC 2=35,0;NIC 3=39,0;CCE=53,8p<0,0001). Surpreendentemente a razäo das taxas proliferaçäo/ apoptose näo mostrou aumento progressivo (NIC 1=75,6;NIC 2=62,7;NIC 3=54,7; CCE=44,2). Conclusäo: Observamos aumento paralelo tanto nas taxas de proliferaçäo como nas de apoptose com o grau das lesöes cervicais. As taxas crescentes de apoptose possivelmente representam a persistência de alguns mecanismos compensatórios de regulaçäo da populaçäo celular

To assess proliferative and apoptotic rates in squamous lesions of the uterine cervix. Materialand Methods: 81 cervical biopsies were classified as cervical intraepithelial neoplasia grade 1 CIN1 = 20,CIN2 = 19, CIN3 = 23 and squamous cell carcinoma (SCC) = 19, according to WHO classification. Histologicalsections were submitted to MIB-1 immunostaining by streptavidin-peroxidase amplification. In situ end-labeling of DNA strand breaks by TUNEL method was used to enhance the detection of apoptosis. Allcells representative of the pertinent lesion were counted in each sample in digital hotomicrographs andthe results were expressed as positive cells %. The groups were compared using a one-way analysis ofvariance (ANOVA). Statistical significance was defined as a P< 0.05. Results: There was progressiveincrease of proliferation rate (%) with the severity of lesion CIN 1 = 22.7; CIN 2 = 34.5; CIN 3 = 38.3; SCC =52.6 p<0.0001). The same was obtained with apoptotic rate (%) (CIN 1 = 0.30; CIN 2 = 0.55; CIN 3 = 0.70;SCC = 1.19 p<0.0001), and turnover rate (%) (CIN 1 = 23.0; CIN 2 = 35.0; CIN 3 = 39.0; SCC = 53.8 p<0.0001).Surprisingly, the ratio of proliferation/apoptotic rate did not show a progressive increase (CIN 1 = 75.6;CIN 2 = 62.7; CIN 3 = 54.7; SCC = 44.2). Conclusions: There is an increase in both proliferation andapoptosis with increasing atypical in cervical lesions. Increase in apoptotic rate possibly representspersistence of some compensatory regulation mechanisms of cell population

DISTRIBUTION OF LANGERHANS CELLS IN HUMAN SQUAMOUS EPITHELIA / 解剖学报

By means of ATPase histochemistry and OKT-6 immunogold-silver staining, it was demonstrated that Langerhans ceils (LC) were present in the epithelia of human skin, palatine tonsil, ectocervix and esophagus. In the skin LC were located mainly in the stratum spinosum of the epidermis. There were some LC in the hair follicle and duct of sebaceous gland, and a few in the dermis and around sebaceous gland acinus. In the tonsil, ectocervix and esophagus, LC were located mainly in the middle layer of epithelia. No LC were found in the lymphoid follicle and thymus-dependent zone of the tonsil, and no LC in the lamina propria of ectocervix and esophagus. ATPase histochemistry was also used to examine the distribution of epidermal LC in normal human skin of various ages and various anatomic regions. This study showed that the density and morphology of epidermal LC varied with age and different anatomic regions of human body. Statistical analysis indicated that LC density in various age groups was as follows: fetus
