The anatomical relations of the sphenoid sinus and their implications in sphenoid endoscopic surgery V. Budu, Carmen Aurelia Mogoanta, B. Fanuta, I. Bulescu Alongside the past development of endoscopic sinus surgery, knowledge about the anatomy of the sinuses has become crucial for surgeons. The sphenoid sinus is one of the most variable of all sinuses. Its relations to vital vascular and nervous elements make its approach a challenge for endoscopic surgeons.

These relations include the internal carotid artery, the optic nerve, the pituitary gland, the Vidian nerve, and other vascular and nervous elements depending on the size of the sinus. This paper will make a review of these anatomical relations and their importance in endoscopic sphenoid surgery. Danciu, M. Onofriescu, Cornelia Amalinei PAX8 and WT1 are transcription factors, each of them with distinct roles in organogenesis, morphogenesis, cell growth, and differentiation.

Papillomatous epidermal nevus, their expression was also confirmed in a variety of malignancies, being included in the antibodies panel recommended papillomatous epidermal nevus the female genital tract pathology.

The aim of our study was to evaluate PAX8 and WT1 in different types of ovarian cancer OC with focus on i the completion of evidences of the Mullerian origin and ii the establishment of primary ovarian tumor status vs.

One case was not valuable due to technical difficulties. PAX8 expression was positive in 70 Our study provide supplementary evidences to support the association of PAX8 and WT1 papillomatous epidermal nevus in the investigation of the complex biology of OC, PAX8 confirming the ovarian primary and WT1 allowing the refinement of the diagnosis in phenotype overlapping cases.

In vitro papillomatous epidermal nevus and characterization of corneal stem cells isolated from an papillomatous epidermal nevus with malignant melanoma O. Samoila, Olga Soritau, M. Calugaru, Lacramioara Totu, S. Susman, Cristina Cristian, Carmen Mihaela Mihu Purpose: The objective of this study was the identification, characterization and in vitro replication of the human corneal stem cells, taking into consideration the difficulties in obtaining sufficient corneal material from living donors.

The study explored a variety of stem cell markers, usually found in embryonic or adult mesenchymal stem cells. Culture medium and replication substrates had to be identified, with no data available on this subject in our country there are no other reports on corneal stem cells in Romania, to our knowledge.

Materials and Methods: Corneal epithelial limbus was harvested from an enucleated eye, containing also a choroid malignant melanoma. Stem cells from the limbus were isolated and cultivated in vitro.

Expression of specific stem cell markers was evaluated with papillomatous epidermal nevus.

A positive statistic correlation resulted between the amounts of TIL in peritumoral and intratumoral location but without correlation to histopathological grading.

Tumor cells and lymphocytes Foxp3 expression was inversely correlated with the amount of TIL. In these conditions, Foxp3 could be a mediator of the tumor cells inhibitory aggression papillomatous epidermal nevus the immune system and could be used as a molecular target for biological antitumor therapy. Histopathologic features of Spitzoid lesions in different age groups Adriana Diaconeasa, D. Boda, C. Solovan, D. Enescu, Alina Maria Vilcea, Sabina Zurac Spitz nevus is one of the most difficult melanocytic lesions to diagnose in regard of malignancy, even for experienced dermatopathologists.

We analyzed 28 tumors with Spitzoid morphology from 15 children three little children year-old, 12 peripubertary children year-old and 13 adults; there were 21 Spitz nevi, papillomatous epidermal nevus atypical Spitz tumors and two Spitzoid melanomas in order to establish the diagnostic value of several morphologic parameters in different age groups. In adults, presence of isolated cells within the lateral margins allows differentiating Spitz nevus from atypical Spitz tumor and Spitzoid melanoma.

Deep located mitoses were statistically associated with Spitzoid melanoma in adults.

Conjunctival Nevus Excision

Ulceration was statistically more frequent in peripubertary patients than in adults, probably due to trauma. In conclusion, presence of worrisome morphologic features pagetoid growth, isolated cells within the lateral papillomatous epidermal nevus or ulceration is correlated to patient's age and less to tumor type; there is no unique morphologic feature to relay on when evaluating a Spitzoid tumor, the final diagnosis being the results of interpretation of multiple clinical, morphologic, immunohistochemical and molecular data and not least dermatopathologist's personal experience.

Raica Idiopathic pulmonary fibrosis is a severe disease, with unpredictable evolution that frequently leads to respiratory failure and death, despite some progresses made in the field of therapy. Basically, the bad prognosis and failure of therapy are the consequence of the lack of data about the molecular events that have as result the extensive fibrosis.

Although the basic lesions were defined many years ago, the pathological classification of pulmonary fibrosis is controversial. In the present work, we papillomatous epidermal nevus the prognostic impact of basic microscopic lesions on a possible new classification that could be related to the patient outcome.

For this purpose, we have investigated 20 cases with idiopathic pulmonary fibrosis and samples of lung parenchyma were obtained by video assisted thoracoscopy. The specimens were processed by usual histological technique and sections were stained with Hematoxylin-Eosin, Masson's trichrome and Gordon-Sweet silver staining.

There were evaluated the lung architecture, the chronic inflammatory infiltrate, macrophages and fibrosis. The distribution and severity of each parameter was converted into points and finally graded from I to IV, with corresponding score from 1 to Our results support the hypothesis that the evaluation of basic lesions could be the basis for a papillomatous epidermal nevus objective classification and staging of lung papillomatous epidermal nevus and, possibly, a better prognostic method and, eventually, a predictor for the response to targeted therapy.

Histopathologically, FL has been graded according to the proportion of centroblasts and stratified into grades FL grade low-gradewhich include cases with few centroblasts, and FL grade 3, divided into grades 3a and 3b, based on the absence of centrocytes in the latter category. Several studies have identified some differences between vaksin hpv gardasil adalah 3a and tratamentul pielii după îndepărtarea papilomelor 3b of FL, with most cases of FL grade 3b being more closely related to diffuse large B-cell lymphoma DLBCL at molecular level.

Several multicenter prospective randomized trials demonstrated an improved outcome when Rituximab R was added to chemotherapy for the treatment of follicular non-Hodgkin's lymphomas and a papillomatous epidermal nevus effect in the quality of life after Rituximab maintenance therapy at these patients.

Conclusions: Low-grade FL was correlated with a good prognosis in patients with FLIPI score ; Rituximab maintenance therapy compared with observation only is safe and prolonged progression free survival at patients with follicular lymphomas treated with R-chemotherapy as first line therapy.

Epidemiological and morphological data of ocular melanocytic lesions Flavia Baderca, Papillomatous epidermal nevus. Solovan, Loredana Boghian Ocular melanocytic lesions comprise a spectrum of lesions ranging from benign nevi to invasive melanoma. Clinical and histopathological appearance of conjunctival lesions ranges from freckle to lentigo and to nevi.

Between these types, conjunctival nevi and conjunctival melanosis are the most frequent. Conjunctival and uveal melanocytes are derived from the neural crest, as their cutaneous counterparts, whereas the papillomatous epidermal nevus epithelial melanocytes are derived from the neuroepithelium or the layers of the optic cup.

Melanomas can develop in one of several places within the eye, and can be divided in uveal melanomas and conjunctival melanomas.

The purpose of the study was to investigate the epidemiological and morphological data of ocular melanocytic lesions, especially intraocular melanoma, through analysis of the ocular biopsies received in the Department of Pathology, Emergency City Hospital, Timisoara, Romania, for the period of five years. We did not observed any gender predilection neither in benign nor in malignant tumors.

In our study, whatever the tumor location was, the most common type of melanomas was mixed with both, epithelioid and spindle cells. In some cases, immunohistochemical investigations are useful to appreciate the benign or malignant character of the tumor. Anatomy and variations of palmaris longus in fetuses S.

A sound knowledge on the anatomy and variations of palmaris longus is of great papillomatous epidermal nevus during surgical interventions; because it is the first choice for tendon grafts, by the virtue of its structure and function. Thus, this study is of academic interest for anatomists and hand surgeons alike. Endometriosis - clinical approach based on histological findings C. Cristescu, Andreea Veliscu, B.

Marinescu, Anca Patrascu, E. Trasca, O. Pop Endometriosis is a benign disease defined by the presence of endometrial glands and stroma outside of the uterus and is associated with both pelvic pain and infertility. The most common sites of endometriosis, in decreasing order of frequency, are the ovaries, anterior and posterior cul-de-sac, posterior broad ligaments, uterosacral ligaments, uterus, fallopian tubes, sigmoid colon, appendix, and round ligaments.

The main treatment is surgical, but often-microscopic islands of endometrial tissue remain, which proliferate and are responsible for relapses. We tested the efficacy of two drugs Medroxyprogesterone and Triptorelinumadministered for six months to prevent recurrence after surgery.

Recent studies support their involvement in oxiuri la femei insarcinate, as changes in CLDNs structure result in alterations in tight junctions' structure and function, facilitating malignant transformation. We aimed CLDN3 investigation in both breast and ovarian carcinoma, targeting the identification of its expression differences.

The immunohistochemical assessment was performed on 20 cases of breast carcinomas Group 1 and 19 cases of epithelial ovarian carcinomas Group 2. Firstly, the specific panel for papillomatous epidermal nevus molecular classification was applied for specimens of the first group.

Then, all the specimens were immunostained for CLDN3 and a semi-quantitative evaluation was made, based on the percentage of positive cells and the intensity of staining. In Group 2, CLDN3 was overexpressed in 15 cases, histopathologically diagnosed as serous 10 casesmucinous two casesendometrioid two casesand mixed carcinomas one case ; a weak expression was noticed in a single case, of the serous subtype; CLDN3 was undetectable in three cases one serous, one clear cell, and one endometrioid type.

Our comparative analysis of CLDN3 profile in breast and ovarian cancer clearly indicates organ specificity. Comparative study of microvascular density in experimental third-degree skin burns treated with topical preparations containing herbal extracts G. Lascar, L.
