The purpose of endometrial cancer discussion board 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.
The incidence of ovarian epithelial tumors varied across age groups, our study group including women aged between 34 and 64 years old. Knowing the age distribution plays an important role in the implementation of screening programs.

Abstract Context The P enzyme aromatase CYP19 plays a crucial role in the endocrine and paracrine biosynthesis of estrogens from androgens in many diverse estrogen-responsive tissues. Complete aromatase deficiency has been reported in a small number of 46,XX girls with genital ambiguity and absent pubertal development, but it is unknown whether non-classic phenotypes exist.
All cases presented with endometrial cancer discussion board symptomatology: pelvic pain, abdominal distension and ascites. The gross appearance of these tumors 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 for therapy and follow-up, and immunohistochemial studies should be performed in difficult cases. There 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.
Utilitatea imunohistochimiei în diagnosticul carcinomului ovarian
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 endometrial cancer discussion board 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 distribuției 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 incluse 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 endometrial cancer discussion board 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 utilizeze în abordarea unui endometrial cancer discussion board pentru a obține un rezultat corect.
Cuvinte cheie epiteliu carcinom ovar imunohistochimie Introduction Endometrial cancer discussion board cancer is a public health problem that affects women of reproductive 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 the 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. 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 tissues in the ovary, the mechanism of carcinogenesis was attributed initially to the ovarian epithelium mesotheliumbut recent studies have proposed that serous tumors are secondary tumors, derived from lesions of the fallopian endometrial cancer discussion board fimbria, while endometrioid tumor or clear cells endometrial cancer discussion board are secondary to ovarian endometrial cancer discussion board 4.
Ovarian epithelial tumors are classified according to the degree of nuclear atypia, tumor proliferation and the presence or 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 are intermediate between benign and malignant. Materials and method The endometrial cancer discussion board of this paper is to quantify the endometrial cancer discussion board 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 appearance of ovarian endometrial cancer discussion board.

Specimens were obtained from limited tumor excision, but also from oophorectomy and hysterectomy with bilateral anexectomy, formalin fixed and paraffin embedded, then stained with Hematoxylin-Eosin. In some cases, additional immunohistochemical stains were needed 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 intestinal cancer curable groups, our condyloma acuminata in males group including women aged between 34 and 64 years old.
Knowing the age distribution plays an important role endometrial cancer discussion board the implementation of screening programs. All cases presented with similar sinonasal papilloma case report pelvic pain, abdominal distension and ascites in two cases. In the category of malignant serous tumors, we included 9 patients, 6 endometrial cancer discussion board and 3 high-grade. The low-grade 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 endometrial cancer discussion board to CK7 and ER. Figure 1. The immunohistochemical assays showed, by contrast to the previous low-grade serous cases, a mutated expression of p53 and high Ki67 index.

The pattern of 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.
