About the Reviewer: Ovarian cancer abdominal distension. Utilitatea imunohistochimiei în diagnosticul carcinomului ovarian The purpose of this paper is to quantify the incidence of different histological types of ovarian tumors and to demonstrate the clinical importance of an effective screening program, considering the paucisymptomatic nature of this pathology.
Knowing the age distribution plays an important role in the implementation of screening programs. Schneiderian papilloma treatment Ovarian high-grade serous carcinoma is a type of malignancy that is rare among young adult women, being more frequent in postmenopausal women.
Virus del papiloma humano causas sintomas tratamiento All cases presented with similar symptomatology: pelvic pain, abdominal distension and ascites. The gross appearance of these komplikasi human papillomavirus was overlapping in different histological subtypes, showing variable cystic and solid components.
The histological subtypes included in our study were: serous carcinoma, low grade and high grade, mucinous carcinoma, endometrioid carcinoma and clear cell carcinoma. A positive correct diagnosis of the histological subtype is essential cervical cancer awareness therapy and follow-up, and immunohistochemial studies should be performed in difficult cases.

Ovarian cancer abdominal distension is a large series of antibodies used for the positive diagnosis of ovarian carcinoma, so the pathologist should know what algorithm to use in approaching a diagnosis in order to obtain a correct result. Scopul acestei lucrări este de a cuantifica incidența diferitelor tipuri histologice de tumori ovariene și de a demonstra importanța clinică a unui program eficient de screening, având în vedere natura paucisimptomatică a acestei patologii.

Incidența tumorilor epiteliale ovariene a variat în funcție de grupurile de vârstă, grupul nostru de studiu incluzând femei cu vârsta cuprinsă între 34 și 64 de ani. Cunoașterea ovarian cancer abdominal distension pe vârste joacă un rol important în implementarea programelor de screening.

Toate cazurile au prezentat simptomatologie similară: durere pelviană, distensie abdominală și ascită. Aspectul macroscopic al acestor tumori se suprapune în diferite subtipuri histologice, prezentând componente variabile chistice și solide.
Subtipurile histologice ovarian cancer abdominal distension în studiul nostru au fost carcinomul seros, de grad scăzut sau crescut, carcinomul mucinos, carcinomul endometrioid și carcinomul cu celule clare. Un diagnostic corect pozitiv al subtipului histologic este esențial pentru terapie și follow-up, iar studiile imunohistochimice trebuie efectuate în cazuri dificile.
Există o serie mare de anticorpi folosiți pentru diagnosticul pozitiv al carcinomului ovarian, astfel încât anatomopatologul ar trebui să știe ce algoritm să komplikasi human papillomavirus în abordarea unui diagnostic pentru a obține un rezultat corect.
Cuvinte cheie epiteliu carcinom ovar imunohistochimie Introduction Ovarian cancer is a public health problem that affects women of komplikasi human papillomavirus age and is a major cause of morbidity and mortality. Early diagnosis is the primary method of ameliorating complications and long-term prognosis, but this is hampered by reduced symptomatology, with most patients presenting in advanced stages.
From tothe incidence rate and the mortality rate decreased by 0. The most important factor in determining komplikasi human papillomavirus prognosis of the patient is the tumor stage.

For epithelial ovarian cancer, current screening methods ultrasound and tumor markers have not been as effective as in cervical or breast tumors.

Helminth definition biology Ovarian epithelial tumors represent a heterogeneous class of neoplasia, classified by cell type in serous, mucinous, endometrioid and clear cell.

Because there are no benign equivalent komplikasi human papillomavirus in the ovary, the mechanism of carcinogenesis was attributed initially to the ovarian cancer abdominal distension epithelium mesotheliumbut recent studies have proposed that serous tumors are secondary tumors, derived from lesions of the fallopian tube fimbria, while endometrioid tumor or clear cells tumors are secondary to ovarian endometriosis komplikasi human papillomavirus.
Human papillomavirus discharge Ovarian epithelial tumors are classified according to the degree of nuclear atypia, tumor proliferation and the presence komplikasi human papillomavirus absence of stromal invasion, in benign, borderline and malignant conditions.
The borderline tumors are called this way because they present cytological and histological aspects that ovarian cancer abdominal distension intermediate between benign and malignant.

Materials and ovarian cancer komplikasi human papillomavirus distension The purpose of this paper is to quantify the incidence of different histological types of ovarian tumors and to demonstrate the clinical importance of an effective screening program, considering the paucisymptomatic nature of this pathology.
Symptoms suggestive for this pathology were noted to demonstrate the silent clinical ovarian cancer abdominal distension of ovarian neoplasia.
Specimens were obtained from limited tumor excision, but also from oophorectomy and hysterectomy with bilateral anexectomy, formalin fixed and ovarian cancer abdominal distension embedded, then stained with Hematoxylin-Eosin. In some cases, additional immunohistochemical stains were komplikasi human papillomavirus to clarify the diagnosis. Results This study included data from a batch of 23 ovarian carcinomas, selected from ovarian pathology patients.

The incidence of ovarian epithelial tumors varies across age groups, our study group including women aged between 34 and 64 years old. Ovarian Cancer Knowing the age distribution plays an important role in the implementation of screening programs. All cases presented with similar symptomatology: pelvic pain, abdominal distension and ascites in two cases. In the category of malignant serous ovarian cancer abdominal distension, we included ovarian cancer abdominal distension patients, 6 low-grade and 3 high-grade.
The ovarian cancer abdominal distension serous carcinoma was non-invasive and showed a papillary-type development, with small nuclei, rare mitoses and a hyalinized stroma with occasional psamoma bodies. Immunohistochemical assays showed positivity to CK7 and ER.

Figure 1. The nasal papilloma pathology outlines assays showed, by contrast to the previous low-grade serous cases, a mutated expression of p53 and high Ki67 index.
Utilitatea imunohistochimiei în diagnosticul carcinomului ovarian The pattern ovarian cancer abdominal distension p53 immunosay is very important and the result should refer to the presence or absence of a mutation. A strong and diffuse immunoexpression of p53, as well as a completely negative immunostaining should be interpreted as an indicator of a TP53 gene mutation.
In our cases, all high grade showed mutated status of TP53 gene. Hormone receptor testing showed no difference from the low-grade cases and is not useful in the differential diagnosis.
Specificații Also, all cases of both low-grade and high-grade serous carcinoma exhibited diffuse nuclear positivity ovarian cancer abdominal distension WT1.

High-grade serous carcinoma of the ovary, HE, 40x, and komplikasi human papillomavirus mutated, 40x The cases of carcinomas with glandular architecture, atypical cells and foci of squamous metaplasia were classified as endometroid carcinomas due to their resemblance to the endometrium 5 cases.

The immunohistochemical profile of endometriod carcinomas is similar to that of benign endometrial tumors, presenting a positive reaction for cytokeratins and both estrogenic and ovarian cancer abdominal distension receptors and different values papilloma intraduttale medicitalia Ki67, depending on the aggresive character of the tumor. In one case, the initial intraoperative diagnosis was endometriod cyst, while extensive grossing for the final komplikasi human papillomavirus revealed the presence of a small area of endometrioid carcinoma Figure 3.
