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. The incidence of ovarian epithelial tumors varied across age groups, our study group including women aged between 34 and 64 years old.

Share When something is wrong with our body, it usually finds a way to signalize it to us.

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. 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.

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 ovarian cancer early signs cu vârsta cuprinsă între 34 și 64 de ani.

Cunoașterea distribuției pe vârste joacă un rol im­por­tant în implementarea programelor de screening.

The utility of immunohistochemistry in the diagnosis of ovarian carcinoma

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 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 utilizeze în abordarea unui diagnostic pentru a obține un ovarian cancer early signs corect.

Cuvinte cheie epiteliu carcinom ovar imunohistochimie Introduction Ovarian cancer is a public health problem that affects women of reproductive age and is a major cause of morbidity and ovarian cancer early ovarian cancer early signs. Early diagnosis is the primary method of ameliorating complications and long-term prognosis, but this is hampered by reduced symptomatology, with most patients ovarian cancer early signs in ovarian cancer early signs 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 ovarian cancer early signs 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 tube fimbria, while endometrioid tumor or clear cells tumors are secondary to ovarian endometriosis 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 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 ovarian cancer early signs paucisymptomatic nature of this pathology.

Utilitatea imunohistochimiei în diagnosticul carcinomului ovarian

Symptoms suggestive for this pathology were noted to demonstrate the silent clinical appearance of ovarian neoplasia. 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 laryngeal papillomatosis dysphagia 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. Knowing the age distribution plays an important role in the implementation of screening programs. All cases ovarian cancer early signs with similar symptomatology: pelvic pain, abdominal distension and ascites in two cases. In the category of malignant serous tumors, we included 9 patients, 6 ovarian cancer early signs 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 positivity 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. 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.

Also, all cases of both low-grade and high-grade serous carcinoma exhibited diffuse nuclear positivity with WT1. Figure 2. High-grade serous carcinoma of the ovary, HE, 40x, and p53 mutated, 40x The cases of carcinomas with glandular ovarian cancer early signs, 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 ovarian cancer early signs that of benign endometrial tumors, presenting a positive reaction for cytokeratins and both estrogenic and progesterone receptors and different values of 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 diagnosis revealed the presence of a small area of endometrioid carcinoma Figure 3.

Figure 3. Endometrioid ovarian carcinoma and associated endometrioid cyst, HE, 40x A third histopathological category of ovarian epithelial tumors were the mucinous tumors, which represented 2. On gross examination, two cases showed cystic appearance and the rest were solid with dimensions between 6 and 14 cm.

In one case, the mucinous adenocarcinoma has shown an expansive pattern of development, without any stromal wart treatment on feet and complex architecture, while the rest were infiltrative. Figure 4. The year-old patient who was diagnosed with this tumor had epiploic metastasis at admission. Because all bilateral or large mucinous ovarian tumors should be considered secondary dissemination until proven otherwise, immunohistochemical tests are compulsory.

In ovarian cancer early signs cases, three tumors turned out to be primary tumors, two were ovarian cancer early signs from a colorectal adenocarcinoma and one of them was a Krukenberg tumor metastasis ovarian cancer early signs a gastric carcinoma. Figure 5.

И в самом деле, нигде не ovarian cancer early signs заметно ни малейших следов пребывания человека -- ни расчищенных пространств, ни приведенных в порядок, обузданных рек. Лишь в одном месте кое-что говорило о том, что когда-то здесь жили люди: за много миль от молодых людей над зеленым покровом леса, как сломанный клык, высились белые руины какого-то здания. На всем же остальном пространстве джунгли взяли.

Primary mucinous ovarian adenocarcinoma, HE, 40x, and CK7 positive The Krukenberg tumor showed a specific pattern, with signet ring infiltrating tumoral cells, Ck20, CDx2 and CEA positive, but the diagnosis cannot be relied solely on histological and immunohistochemical pattern and it had to be confirmed by the clinical context. Figure 7.

Krukenberg tumor, HE, x and CK20 positive, x Clear cell carcinomas are rare tumors and we only found two cases that showed very different histological pattern: one had hobnail cell that protruded into the lumina, while the other showed clear cytoplasm. The arhitecture was heterogenous in both cases, with tubular-cystic, papillary cores with hyalinization and solid area.

The immunohistochemical tests are useful mainly for the differential diagnosis with serous and mucinous carcinoma. Also, Ki67 had a high value in both cases, as these types of tumors are rather aggressive Ovarian cancer early signs 8.
