Cystoscopy revealed a nodular mass measuring 4 cm in diameter in the posterior wall, and total cystectomy was performed. Endocervical adenocarcinoma pathology outlines Pathology Outlines - HPV related Adenocarcinoma (usual . Most cases of cervical adenocarcinoma in situ (AIS) and adenocarcinoma are of the usual or endocervical type. 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. Surface epithelium is endocervical glandular type and may show squamous metaplasia, erosion and reactive / reparative changes. An immunohistochemical comparison with microglandular endocervical hyperplasia and conventional endocervical adenocarcinoma. An introduction to cytopathology is in the cytopathology article..

However, occasional endometrial … B, High power shows nuclear pleomorphism, large cherry-red nucleoli, and abundant mitotic figures and apoptotic bodies. Gynecologic cytopathology is a subset of cytopathology. Invasive endocervical adenocarcinoma: proposal for a new pattern-based classification system with significant clinical implications: a multi-institutional study Int J Gynecol Pathol . Gastric type adenocarcinoma in situ. A 22 year old woman undergoes routine Pap screening. This diagnosis is relatively rare and may portend a worse prognosis than usual‐type endocervical adenocarcinoma. Flat sheets, school of fish appearance, preserved nuclear cytoplasmic ratio, evenly dispersed chromatin with prominent nucleoli.

Rare groups or strips, powdery or watery chromatin, no other patterns of adenocarcinoma in situ, no mitotic and apoptotic bodies, terminal bars and cilia are key diagnostic features. Histology revealed that the elevated lesion of the bladder wall was composed of haphazard proliferation of cystic glands lined by benign endocervical‐type epithelium.

Gastric‐type endocervical adenocarcinoma (GAS) is an uncommon type of endocervical adenocarcinoma that is not associated with human papillomavirus infection. A new 3-tier pattern-based system to classify endocervical adenocarcinoma was recently presented. Abstract. 2013 Nov;32(6):592-601. doi: 10.1097/PGP.0b013e31829952c6. Her results reveal atypical endometrial cells. However, we cannot answer medical or research questions or give advice. Adenocarcinomas typically occur within the endocervical canal. Endocervical gastric-type adenocarcinoma (GAS) is a rare non-human papillomavirus-associated adenocarcinoma (NHPVA) with morphologic and immunohistochemical features of gastric differentiation. 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. This website is intended for pathologists and laboratory personnel but not for patients. An adenocarcinoma arose at the center of this endocervicosis. Atypical lobular endocervical glandular hyperplasia has been identified in 30% of minimal deviation adenocarcinomas. ER was negative in 16 of 26 endocervical adenocarcinomas, and there was focal weak nuclear staining in the other cases. 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. 6 Du ZS and Zhao Q: Clinicopathological observation of minimal deviation adenocarcinoma. Lobular endocervical glandular hyperplasia (LEGH) has been identified adjacent to up to 50% of minimal deviation adenocarcinomas and 20% of gastric type adenocarcinomas.

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. Abstract. 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)
