Atvejis Pacientas, 37 metų, trejus metus gydytas nuo lėtinio prostatito. Prostatos sekrete nustačius atipinių ląstelių, įtarus prostatos vėžį, ligonis nusiųstas į VU Onkologijos institutą. Tyrimo pro tiesiąją žarną, cistoskopijos, rentgenologinio, ultragarso ir serumo žymenų tyrimo duomenimis, diddesnių pokyčių nerasta. Atlikus transuretrinę šlapimo pūslės gleivinės biopsiją (TUR) iš šlapimo pūslės sienelių, kaklelio ir šlaplės prostatinės gleivinės, histologiškai nustatyti normalūs urotelio audiniai. Šlapimo citologinis tyrimas buvo neigiamas. Atlikus transrektalinę prostatos biopsiją, diagnozuotas prostatos urotelio navikas, imunohistochemiškai neigiamas PSA (prostatos specifiniam antigenui) ir teigiamas citokeratinams CK8 ir CK HMW. Pacientui buvo atlikta radikali cistoprostatektomija, pašalinti dubens limfmazgiai ir suformuotas šlapimo nuotėkis į ileum segmentą, išvestą į priekinę pilvo sieną (Brycker būdu). Morfologinė diagnozė – prostatos urotelio karcinoma. Taip pat diagnozuota prostatos adenokarcinoma ir prostatos intraepitelinė neoplazija. Po 15 mėnesių PSA lygis buvo 0,2 ng/ml, jokių ligos progresavimo požymių nepasireiškė. Remiantis šiuo klinikiniu atveju straipsnyje apžvelgiama literatūra, aiškinantis prostatos urotelio karcinomos ir adenokarcinomos skirtumus. Išvados Diagnozuojant prostatos urotelio karcinomą reikia vadovautis tam tikrais kriterijais: 1) prostatos urotelio karcinoma turi būti verifikuota makro-, mikroskopiškai ir imunohistocheminiais metodais, 2) neturėtų būti kitų urotelio karcinomos židinių organizme. Būtent prostatos biopsija leidžia patologui nustatyti tikslią diagnozę prieš operaciją. Imunohistocheminis tyrimas padeda atlikti diferencinę diagnostiką. Po operacijos tiriant pašalintus audinius, diagnozė patikslinama histomorfologiškai, naudojant imunohistocheminius tyrimus, net jei ir labai retai nustatoma prostatos urotelio karcinoma.

Case report with literature overview Algimantas Sruogis1, Ugnius Mickys2, Tadas Petraitis1, Edita Kaubrienė3, Feliksas Jankevičius11 Vilnius University Institute of Oncology,Urology Department,Santariškių str. 1,LT-08661 Vilnius, LithuaniaE-mail: [email protected] Lithuanian National Centre of Pathology3 Vilnius University Institute of Oncology,Radiology Department Objective To establish criteria for the diagnosis of primary urothelial prostate carcinoma after the differential diagnosis including high-grade urothelial carcinoma extending into the bladder neck and prostate versus poorly differentiated prostate adenocarcinoma extending into the bladder. Case report The patient was a 37-year-old man with severe prostatism symptoms, who presented with an atypical seminal vesicles fluid cytological test result. The prostate was also normal by the digital examination, endoscopy, roentgenography, ultrasonography and serum markers. A diagnostic transurethral resection of bladder mucosa, bladder neck specimen revealed normal urothelial tissues. The urine cytological test result was negative. The transrectal biopsy of the prostate revealed an urothelial carcinoma with a negative staining of PSA (prostate-specific antigen) and positive of cytokeratins CK 8 and CK HMW. The patient subsequently underwent radical cystoprostatectomy and pelvic lymphadenectomy with ileal conduit m. Brycker creation. The histological diagnosis was the urothelial carcinoma of the prostate. Also, the prostate showed foci of High Grade PIN and prostate adenocarcinoma. After 15 months the patient has a PSA level of 0.2 ng/mL, no symptoms, no evidence of progression. Based on this case of the urothelial carcinoma of prostate, the literature was reviewed and the morphological differentiation between urothelial carcinoma and adenocarcinoma of the prostate was discussed. Conclusions The diagnostic criteria are the following: (1) the tumor should be a macro-, microscopically and imunohistochemically verified as urothelial carcinoma localized exclusively in the prostate gland; (2) there must be no other primary urothelial carcinoma in the body. These criteria can be readily applied when evaluating surgical resection specimens. With the use of radiologically guided or endoscopically derived biopsies, however, the pathologist is increasingly called upon to make a diagnosis before definitive surgical resection. In these circumstances, the pathologist will often resort to immunostains to help refine the differential diagnosis. Moreover, even when surgical resection specimens are evaluated, immunostains are still used in conjunction with histomorphology to confirm the diagnosis, particularly when a rare entity such as primary urothelial prostate carcinoma is encountered.

Abstract Introduction Textiloma (Txm) is a nonmedical term that has been given to foreign body-related inflammatory pseudotumor arising from retained nonabsorbable cotton matrix that is either inadvertently or deliberately left behind during surgery, which may trigger an inflammatory reaction. This report describes a case of Txm mimicking a recurrent high-grade astrocytoma. Case Report We, here, present the case of a 69-year-old female with a 6-month history of progressive left-sided weakness. Neuroimaging studies revealed a large nonenhancing mass in the right frontoparietal lobe. Pathology reported a World Health Organization tumor classification grade II, diffuse astrocytoma. After surgical intervention, external beam radiation was given to the remaining areas of residual tumor. Routine magnetic resonance imaging (MRI) revealed a nodular area of contrast enhancement in the dorsal and inferior margin of the biopsy tract, growing between interval scans, and perfusion-weighted imaging parameters were elevated being clinically asymptomatic. She underwent a complete resection of this area of interest and pathology returned as a Txm with Surgicel fibers. Conclusion After treatment of a neoplasm, if unexpected clinical or imaging evidence of recurrence is present, a foreign body reaction to hemostatic material used during the initial surgery should be included in the differential diagnosis.

Abstract Pediatric high-grade gliomas are rare and often hard to classify, which grow locally and show longer survival than diffuse high-grade gliomas in adults. We report a case of circumscribed high-grade astrocytoma who was initially diagnosed as glioblastoma and has 20 years survival. A 7-year-old girl suffered from epileptic seizure due to a left occipital lobe tumor. The tumor was resected in another hospital and diagnosed as glioblastoma. The tumor disappeared after extended local irradiation and chemotherapy using nimustine hydrochloride (ACNU) and cisplatin (CDDP). Eighteen years after initial onset, first recurrence was confirmed as the intra-tumoral hemorrhage. The tumor was resected and diagnosed as anaplastic oligoastrocytoma. After 6 courses of temozolomide (TMZ), the tumor disappeared. Twenty years after initial onset, the second local recurrence was confirmed. Although gamma knife and TMZ was performed, the tumor did not disappear. The tumor was surgically resected. Histopathology showed localized growth with some infiltration and mitosis but lacked pseudopallisading and microvascular proliferation. The tumor was diagnosed as circumscribed high-grade astrocytoma. Immunostaining revealed ATRX nuclear loss and CDKN2A / B homozygous deletion. After 10 courses of TMZ, the third local recurrence was confirmed. The tumor was completely removed and has not occurred recurrence more than 3 months after the last operation. Circumscribed high-grade glioma is expected to survive longer than invasive glioma. Pediatric gliomas should differ from adult gliomas in the genes of tumorigenesis. Care should be taken for its diagnosis and treatments. We also need a new classification based on histology and gene profile.

PURPOSE: Recent advances in genetic interrogation of pediatric glioma increase the importance of molecular diagnosis using surgical specimen. However, surgical resection may be avoided to preserve quality of life, especially in brain stem glioma cases. We retrospectively examined diagnosis and treatment of pediatric gliomas in our hospital. METHODS: This study includes 14 consecutive glioma patients under the age of 18 who underwent initial treatment at our hospital from 2000 to 2019. Histopathological diagnosis, clinical course and molecular status such as IDH, H3F3A and BRAF were analyzed. RESULTS: 5 patients (1 pilocytic astrocytoma (PA), 3 diffuse astrocytomas, 1 oligodendroglioma were treated only by surgical resection (group A). 7 patients (1 PA, 1 anaplastic oligodendroglioma, 2 diffuse midline gliomas and 3 glioblastomas (GBM)) received radiation and/or chemotherapy after surgical resection (group B). 2 diffuse intrinsic pontine gliomas (DIPG) received radiation and chemotherapy without surgical resection (Group C). No IDH mutation was observed in all pathological specimen obtained cases. BRAF alteration was observed in all PA cases. 1 case of GBM had BRAF V600Emutation and the other had H3K27M mutation. During a median of 7.7 years of follow-up, group A patients have no recurrence. Group B includes various diagnosis and prognosis. 2 group C patients diagnosed DIPG by MRI showed different clinical courses. CONCLUSION: Pediatric gliomas include diverse biological subgroups and show broad range of clinical behavior. Since pediatric glioma has a low incidence and a wide variety of genetic mutations, multicenter study is important to improve the treatment of pediatric glioma.

Obturator prostheses are considered to be the preferred choice for the restoration of maxillary defects. Patients with palatal insufficiency, speech and deglutition becomes impaired, thereby requiring prosthodontic rehabilitation. The prosthodontic rehabilitation of patients with acquired defects of the maxilla after surgical resection is the complete responsibility of a maxillofacial prosthodontist. He has to recreate an artificial barrier between the cavities and thus restore the functional capabilities of speech, mastication and swallowing. Palatal obturator is the only substitute which covers the defect and contributes to normal speech production. It eliminates hypernasality and improves the communication.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13983 Update Dent. Coll. j. 2011: 1(2): 25-28

Background & Aims: Colorectal cancer represents the third most common malignancy and the fourth most common cause of cancer death worldwide. The existence of drug-resistant colon cancer stem cells is thought to be one of the most important reasons behind treatment failure in colon cancer, their existence putatively leading to metastasis and recurrences. The aim of our study was to investigate the immunoexpression patterns of CD133 and CD166 in colon carcinoma, both individually and in combination, assessing their significance as prognostic markers.Methods. A total of 45 retrospective colon adenocarcinoma cases were investigated by enzymatic and multiple fluorescence immunohistochemistry for their CD133 and CD166 expression and colocalization.Results. Both CD133 and CD166 were expressed to different extents in all cancer specimens, with apredominant cytoplasmic pattern for CD133 and a more obvious membranous-like pattern for CD166.Overall, when comparing their reactivity for the tumoral tissue, CD166 expression areas seemed to be smaller than those of CD133. However, there was a direct correlation between CD133 and CD166 expression levels throughout the entire spectrum of lesions, with higher values for dysplastic lesions. Colocalization of CD133/ CD166 was obvious at the level of cells membranes, with higher coeficients in high grade dysplasia, followed by well and moderate differentiated tumours.Conclusions. CD133/CD166 colocalization is an early event occurring in colon tumorigenesis, with thehighest coeficients recorded for patients with high grade dysplasia, followed by well differentiated tumours. Thus, we consider that the coexpression of these two markers could be useful for further prognostic andtherapeutically stratification of patients with colon cancer.Abbreviations: AJCC - American Joint Committee on Cancer; CCD - charge-coupled device camera sensor; CD133 - prominin-1 (PROM1); CD166 - Activated Leukocyte Cell Adhesion Molecule (ALCAM); CRC - colorectal cancer; CSC - cancer stem cells; DAB - 3,3'-diaminobenzidine chromogen; DAPI - 4',6-diamidino- 2-phenylindole; HE - Hematoxylin and eosin staining; HGD - high grade dysplasia; HRP - horseradish peroxidase; LGD - low grade dysplasia; SDS - sodium dodecyl sulfate*Part of this work has been accepted as a poster presentation at the Digestive Disease Week (DDW) meeting, Chicago, IL, USA May 3-6, 2014
