endocervical adenocarcinoma pathology outlines
6 Du ZS and Zhao Q: Clinicopathological observation of minimal deviation adenocarcinoma. After conization, positive endocervical margins increase risk of residual or recurrent in-situ disease (19.4% with positive margins versus 2.6% with negative margins) and subsequent diagnosis of invasive adenocarcinoma (5.2% with positive margins versus 0.1% with negative margins) (Am J Obstet Gynecol 2009;200:182.e1) While endocervical adenocarcinoma is comprised of several histological subtypes, the most common subtype is human papillomavirus-associated usual type, and management of these tumours is primarily determined by FIGO (International Federation of Gynecology and Obstetrics) stage, a clinically based staging system. The human papilloma virus (HPV) infection is a major cause behind the development of Endocervical Adenocarcinoma, Usual Type. Invasive adenocarcinoma is the second most common malignancy of cervix (after squamous . 71 Strong diffuse positivity involving 100% of cells is the rule in primary endocervical adenocarcinoma, whereas endometrial adenocarcinoma usually exhibits a lesser degree of staining. An adenocarcinoma arose at the center of this endocervicosis. Cystoscopy revealed a nodular mass measuring 4 cm in diameter in the posterior wall, and total cystectomy was performed. Her results reveal atypical endometrial cells. This diagnosis is relatively rare and may portend a worse prognosis than usual‐type endocervical adenocarcinoma. Lack abrupt transition to normal endocervical cells, often associated with inflammatory infiltrate, typically dispersed chromatin with prominent nucleoli. Adenocarcinomas typically occur within the endocervical canal. Endocervical adenocarcinoma pathology outlines Pathology Outlines - HPV related Adenocarcinoma (usual .

This website is intended for pathologists and laboratory personnel but not for patients. With an intestinal-type adenocarcinoma in the cervix, the question may arise as to whether one is dealing with a primary cervical neoplasm or direct or secondary spread from an intestinal adenocarcinoma. cell carcinoma) ... and human papillomaviruses as applied to endocervical pathology. Gynecologic cytopathology is a subset of cytopathology. endocervical adenocarcinomas. Click, 30100 Telegraph Road, Suite 408, Bingham Farms, Michigan 48025 (USA). In all cases the origin of the adenocarcinoma was confirmed by examination of the definitive pathology specimen. Nearly all cases of cervical squamous cell carcinoma are associated with high risk HPV and arise from a precursor lesion, HSIL. History of previous cervical conization or loop excision, abundant ciliated cells, Enlarged nuclei with smudged chromatin, preserved nuclear cytoplasmic ratio, vacuolated cytoplasm, no pseudostratification, no apoptotic bodies or mitoses, Infiltrating glands with irregular, haphazard or confluent growth with desmoplastic stromal reaction and extension beyond benign endocervical glands, Should be differentiated from SMILE, polygonal cells with intercellular bridges lacking intracytoplasmic mucin. However, we cannot answer medical or research questions or give advice. For the cytology see Endocervical adenocarcinoma in situ (cytology) Endocervical adenocarcinoma in situ, also adenocarcinoma in situ of the uterine endocervix, is pre-invasive change of the uterine endocervix. Atypical lobular endocervical glandular hyperplasia has been identified in 30% of minimal deviation adenocarcinomas. 1986.

however, exfoliated malignant cells may be present in cervicovaginal cytology preparations, Cytologic findings are dependent on the grade of the tumor; histologic grade 1 tumors shed few abnormal cells with minimal atypia, whereas higher grade tumors shed cells exhibiting greater pleomorphism, Prolonged exposure to endogenous or exogenous estrogen leads to continued proliferation of the endometrium, Most occur "de novo" with no identifiable precursor lesion, Serous intraepithelial carcinoma is the proposed preinvasive precursor lesion of endometrial serous carcinoma, Unopposed hyperestrogenism, usually in the context of chronic anovulation, obesity or estrogen hormone replacement therapy, Uncertain; often no history of hyperestrogenism, Cervical smear is 45% sensitive in detecting endometrial adenocarcinoma (, Cervical smear is useful to detect cervical involvement of endometrial carcinoma (, ThinPrep may be more sensitive than conventional smears (, Low risk (< 2%) of nodal spread if normal cervical smear (, Cervical Pap test is primarily a screening test for cervical lesions and is not intended for detection of endometrial lesions; however, if atypical glandular cells are seen, further investigation is required to rule out neoplasia (, Cervical Pap cytology is atypical, suspicious or positive for malignancy in 38% to 90% of endometrial adenocarcinomas (, Tend to have a favorable prognosis after hysterectomy, Histologic type, FIGO stage, histologic grade, angiolymphatic invasion (particularly for stage 1 tumors), ER, p53, HER2 and ploidy, 40 year old woman with a history of polycystic ovaries with peritoneal keratin granulomatosis associated with endometrioid adenocarcinoma (, 45 year old woman with synchronous endometrial and ovarian cancer (, 62 year old woman with intestinal differentiated mucinous adenocarcinoma of the endometrium with sporadic MSI high status (, Grade 1: hysterectomy is treatment of choice for patients whom fertility is not a consideration, Young women who desire fertility preservation may be treated nonsurgically, Postoperative radiation if myometrial invasion > 50% thickness, Grade 2: initial treatment is hysterectomy with postoperative radiation therapy to patients with myometrial invasion, Grade 3: most cases have invaded the myometrium at the time of hysterectomy; adjuvant chemotherapy is often warranted, Small, tight clusters or single round cells, Enlarged (become larger with increasing grade of tumor), hyperchromatic nuclei, Small to prominent nucleoli (become larger with increasing grade of tumor), Scant, cyanophilic, often vacuolated cytoplasm, Mitotic figures and apoptotic bodies present, Intracytoplasmic neutrophils within single cells or small groups ("bags of polys"), In liquid based preparations, three dimensional groups and clusters or papillary configuration are common, "Watery" or finely granular tumor diathesis is variably present; in liquid based preparations, it is often less prominent and identified as finely granular debris clinging to the periphery of clusters of cells, In 2013, the Cancer Genome Atlas (TCGA) Research Network published an integrated genomic characterization of endometrial carcinoma based on genomic data from array and sequencing based technologies; it proposed a classification that separates endometrial carcinomas into four groups (, Microsatellite stable tumors that account for 6% of low grade and 17% of high grade endometrioid endometrial carcinomas, Account for 29% of low grade and 54% of high grade endometrioid endometrial carcinomas, Almost all (92%) of tumors have somatically altered PI3K pathway, Accounts for 60% of low grade and 9% of high grade endometrioid carcinomas; 2% of serous carcinomas and 25% of mixed histology carcinomas, Accounts for > 95% of serous carcinomas and 75% of mixed histology carcinomas, Distinction from invasive endometrial adenocarcinoma is problematic and often not possible in cytology specimens, If tumor diathesis is present or cells are round with prominent nucleoli, the tumor is more likely invasive adenocarcinoma, Large vacuolated cells associated with neutrophils, Histology reveals polyp with reactive endocervical cells, No feathering, nuclear palisading or chromatin clearing present, Cells are indistinguishable morphologically from those of endometrial adenocarcinoma but their cellularity is scant, Associated with contraceptive drugs and pregnancy, Cytologic features vary and may include clear cells or aggregates of cells in strips, sheets, papillae, rosettes or corolla-like arrangements, Should have no or rare foci of atypia, mitotic figures, apoptotic bodies or watery diathesis present (, Cells are more columnar and more commonly shed as sheets of cells in comparison to endometrial adenocarcinoma cells, which are more round and tend to exfoliate as single cells and small clusters, Histiocytes are not seen in endocervical adenocarcinoma, Usually the cytopathologist can only suggest or favor one site over another and final classification is made on histology, Rare cells with features dependent on primary location, More commonly associated with psammoma bodies, Rare and often associated with a maternal history of DES exposure during pregnancy, Diagnostic excisional procedure with interpretable margins.
