Lymphadenopathy is a common clinical finding, affecting patients of all ages. The majority of lymphadenopathies are reactive processes of lymph nodes in response to a variety of exogenous and endogenous stimulants. They are non-neoplastic conditions that can mimic lymphoma and other malignant tumors. Therefore their recognition and differential diagnosis is of great importance in order to rule-out the neoplastic disease. Signs of malignant etiology include lymph nodes >1,5cm in diameter, supraclavicular localization and generalized lymphadenopathy. A metastatic carcinoma is always in the differential diagnosis of localized lympadenophaty in older individuals. In case of generalized lymphadenopathy lymphomas, metastatic solid tumors and various benign etiologies need to be considered. The reactive lymphadenopathies are grouped into four major categories according to their predominant architectural histologic pattern: follicular-nodular, sinus, interfollicular or mixed, and diffuse. As reactive conditions of the lymph nodes are dynamic processes the predominant pattern may differ depending on when during the course of the disease the biopsy is performed. The most common reactive lymphadenopaties are follicular hyperplasia and toxoplasmic lymphadenitis. Nowdays some lymphadenopathies with foreign-body reaction are side effects of silicone prostheses (silicone lymphadenopathy) and various contrast media (lipid lymphadenopathy). A specific diagnosis and differentiation from neoplastic disease often requires correlation among the morphologic features, the clinical history, serologic studies, immunohistochemistry and molecular genetic analysis.

Plasma cells (PC) are the terminally differentiated effector cells of the B-cell lineage. The aim of this review is to integrate relevant data on the phenotype of plasma cells, including reactive and malignant PC. The current World Health Organisation classification of lymphoid neoplasm is based on correlation of their morphologic, histologic, immunophenotypic, genetic and clinical features. The extensive application of imunohistochemistry is necessary in diagnosis of plasma cell neoplasm, but also in determining prognosis as well as in evaluating residual/ relapsing disease. This review focuses on immunohistochemical analysis non-neoplastic and neoplastic plasma cell proliferation in facilitating the diagnosis and highlights the recent advances that have been made with regard to their stratifying.

The aim of our study was to evaluate the possibility of ultrasonography in differentiating malignant from nonmalignant cysts in postmenopausal women. The study included 100 postmenopausal women with diagnosis of simple ovarian cysts who were treated surgically at our clinic during the study period. In the group of operated patients the histopathological diagnosis confirmed benign cysts in most cases. In 1% of patients histopathological diagnosis was borderline or malignant tumor of the ovary. The risk of malignancy ranged from 0% in the cyst with a diameter below 50 mm, to 3.57% in cysts over 80 mm. Cyst diameter smaller than 50 mm and the volume of cyst less than 50 cm3 in correlation with the values of serum CA125 and clinical findings represent good algorithm for differentiating malignant from nonmalignant simple cyst.

Gastric carcinoma is usually diagnosed using radiologic contrast methods, endoscopic examination with biopsies and histological analyses. In order to determine the stage of the disease, preoperative diagnosis requires determining presence of distant metastasis, malignant lymph node transformation, and involvement of the surrounding structures. Standards for gastric carcinoma staging have international variations, but all of them are based on the routes of metastasis. Different imaging methods are used for diagnosis and staging of gastric carcinoma, each with its advantages and shortcomings, so guidelines for diagnosis and follow-up for this malignoma are established accordingly.

Postoje kontroverze vezane za vreme, vrstu i metod skrininga gestacionog dijabetesa, kao i za populaciju trudnica koju treba podvrgnuti skriningu. Iako najšire primenjen, glucose chalenge test, kao i alternativne metode skrininga različitim glikemijskim vrednostima, ne pokazuju dovoljno visoku specifičnost. Zato se traže alternativne metode skrininga. Osim o kontroverzama skrininga, ovaj pregledni članak razmatra u

Savremeni svetski stavovi podrazumevaju limfadenektomiju kao terapijsku proceduru koja je integralni deo radikalne hirurgije karcinoma želuca. Ona se izvodi u pokušaju da se hirurgija malignoma učini što radikalnijom. Cilj svake hirurške procedure je potpuno uklanjanje tumora i svakog tkiva koje njime može biti zahvaćeno. Težnja radikalne hirurgije je u eradikaciji maligne bolesti, a limfadenektomija bitno doprinosi ovom cilju. Limfadenekotmija kod gastričnog karcinoma podrazumeva disekciju limfnih nodusa prve, druge grupe, što se smatra standardnom limfadenektomijom D2. Pored hirurškog načina lečenja karcinoma želuca, koji je ostao dominanatan, u poslednje vreme se razvijaju novi modaliteti lečenja želuca. I pored isticanja u prvi plan značaj hirurškog lečenja i sistematske limfadenektomije, kriterijumi koje je dalo Japansko udruženje za gastrični kancer od 2010g. razlikuje i druge modalitete lečenja gastričnog karcinoma. Karcinome želuca možemo tretirati: endoskopski, laparoskopski, klasičnom hirurškom resekcionom operacijom, hemioterapijom (koja može biti preoperativna i postoperativna) i palijativnom hirurgijom. Svaki od ovih modaliteta lečenja utiče na bolji ishod bolesti pacijenata. Izbor adekavtnog tretmana pacijenta sa karcinomom želuca zavisi od stepena uznapredovalosti maligne bolesti.

Pregledom literature utvrdili smo da su primarni tumori slezine u dece jako retrka pojava, a angiom slezine u dece ispod pet godina je jako redak. Mi prikazujemo redak slučaj angioma u donjem polu slezine u dečaka uzrasta pet godina.Detetu je tokom rutinskog ultrazvučno pregleda bubrega nađena masa koja je na CT okarakterisana kao tumor donjeg pola slezine zbog koga je dete operisano. Dete je praćeno dve godine po operaciji. Dijagnoza i opcije lečenja su široko razmatrane. Angiom slezine je redak tumor u odnosu na druge uzroke abdominalnih masa u dece. Konačna dijagnoza je postavljena histopatološkom i imunohistohemijskom analizom od strane dva patologa i glasi: angioma slezine. Primarni tumori slezine u dece se jako retki a naročito angiom. Parcijalna splenektomija ili parcijalna embolizacija slezine su metode izbora kad je moguće kod primarnih tumora slezine u dece.

Prezentujemo slučaj obolele od akromegalije, sa prisutnim kožnim visuljcima na vratu i aksilama, kod koje su kolonoskopski detektovani brojni polipi kolona. Akromegalija je hronična endokrinopatija, najčešće uzrokovana adenomom hipofize koji sekretuje hormon rasta (somatotropinom). Povezanost akromegalije sa nastankom neoplazija još uvek je stvar debate i pored brojnih in vitro i in vivo dokaza. Ipak, maligniteti su na trećem mestu uzroka smrti u obolelih od akromegalije. Najučestalije neoplazije se detektuju u kolonu. Prisustvo izvesnih kliničkih znakova (npr. kožnih visuljaka), može ukazati kliničaru na postojanje prevage proliferativnoneoplastične IGF1 aktivnosti (npr. u kolonu). Sa tim u vezi, dužnost kliničara je da preduzme odgovarajuće dijagnostičke procedure u cilju detekcije neoplazija.

According to the relevant investigations during past decade there is a great increase of malignant skin tumors. By this research we tried to investigate this hypothesis in domestic population and present complicated reconstructive procedure. In this research were included 591 patients with melanomas and carcinomas of head and neck, who were surgically treated at our clinic from 2000. to 2010. Results of this research showed that 50 patients had melanoma and 541 carcinomas of skin. We have found that men are four times more affected by skin facial carcinomas than women. 62% patients with squamous cell carcinoma, who were primary surgically treated, survived more than 5 years. On other hand, 85% patients with basal cell carcinomas survived more than 5 years.

The overall survival rate in infants affected by congenital heart disease remains low. The poor outcome may be related to the increased association with extracardiac anomalies and aneupoloidy. Since most types of CHD are now amenable to surgery, it is essential that any fetus with congenital structural heart defect should be completely evaluated, noting in particular congenital extracardiac defects which may adversely affect the prognosis. Noncardiac malformations have been reported to occur in up to 50% of patients with congenital heart disease. The combination of cardiac anomalies with other organ abnormalities appears in genetic syndromes and after exposure to environmental factors. Fetuses with prenatally diagnosed cardiac malformations need to have offer structural abnormalities ruled out. They should be evaluated thoroughly by ultrasound exam, because the detection of an extracardiac anomaly may dramatically affect prognosis. Also, fetuses in which an extracardiac anomaly or chromosome abnormality is diagnosed deserve a complete evolution with full fetal echocardiography. Fetal caryotype analysis should be performed since the risk of aneuploidy approaches 40% in cases of prenatally diagnosed CHD.
