1/5. Cytology of polypoid adenomyomas: a report of two cases.Uterine polypoid adenomyomas, both typical and atypical variants, often arise in the lower uterine segment or endocervical canal as pedunculated polypoid masses that may be accessible for cytologic sampling. However, their cytologic findings have rarely been described in the literature. Two women in their reproductive age presented with abnormal vaginal bleeding. The cervicovaginal smear of the first patient contained sheets and strips of reactive endocervical cells in an inflammatory background. In addition, loose aggregates of spindle-shaped smooth muscle cells were also noted. The findings were consistent with those of a typical polypoid adenomyoma. The cervicovaginal smears of the second patient consisted of tightly packed, crowded clusters of glandular cells which were initially interpreted as atypical glandular cells, suspicious of adenocarcinoma. In retrospect, loose aggregates of smooth muscle stromal cells were noted. Subsequent curettage revealed an atypical polypoid adenomyoma. The cytologic findings of typical polypoid adenomyoma were nonspecific except for the presence of loose aggregates of smooth muscle cells. The cytologic features of an atypical polypoid adenomyoma may mimic that of a neoplastic glandular process. The findings of tightly packed clusters of glandular cells and loose aggregate of bland-appearing smooth muscle cells in premenopausal patients may suggest the diagnosis of atypical polypoid adenomyoma.

2/5. Brunner's gland polyp with upper gastrointestinal bleeding managed by endoscopic polypectomy: a report of two cases.We report 2 rare cases of Brunner's gland adenoma presenting with upper gastrointestinal bleeding. They were removed by endoscopic polypectomy. In skilled hands, this method is safe and effective.- - - - - - - - - - ranking = 1.25keywords = gland (Clic here for more details about this article) |
3/5. Non-familial juvenile polyposis with histological evidence of adenomatous transformation.A 14-year-old male presented with abdominal pain, diarrhoea and a sensation of something prolapsing through the anus during defecation, and was found to have diffuse colonic polyposis. There was no evidence of mucocutaneous hyperpigmentation and family history was negative, suggesting a diagnosis of non-familial juvenile polyposis. Histological analysis of multiple endoscopic biopsies showed features typical of juvenile or retention type (hamartomatous) lesions: dilated cystic glands lined by mucocus-secreting epithelium and prominent, inflamed and congested lamina propria. However, admixed with these features, focal areas of atypical adenomatous changes were recognized. Even the intervening normal-looking colonic mucosa showed some dysplastic changes. These findings indicate that hamartomatous and atypical adenomatous epithelial changes can co exist in non-familial juvenile polyposis and the latter may confer a risk of malignant transformation in this otherwise non-neoplastic disease.- - - - - - - - - - ranking = 0.25keywords = gland (Clic here for more details about this article) |
4/5. A carcinoma in situ arising in an endocervical polyp--a case report.A rare case of a carcinoma in situ arising from an endocervical polyp is described. The covering epithelium of the polyp transformed gradually into a carcinoma in situ via squamous metaplasia and dysplasia, spreading horizontally with glandular involvement, and colliding with the surface columnar cells. The lack of tumor tissue in the pedicle and adjacent cervical region confirms the case was a carcinoma in situ originating from the surface epithelium of the endocervical polyp.- - - - - - - - - - ranking = 0.25keywords = gland (Clic here for more details about this article) |
5/5. adenosarcoma of the uterine cervix presenting as a cervical polyp.A case of adenosarcoma arising from the uterine cervix of a 55-year-old female who complained of vaginal discharge is reported. A polyp, 6 x 2 x 1.5 cm in size, identified in the cervical canal was clinically diagnosed as benign cervical polyp and resected. Histologically, the polyp was composed of benign epithelial components and sarcomatous stroma wherein periglandular hypercellularity and some mitoses including atypical ones were noted. Immunohistochemically, stromal cells were positive for muscle-type actins, desmin and estrogen receptor. adenosarcoma is a rare, biphasic tumor of the uterus and usually presents as a polypoid mass in the endometrial cavity. When they arise from the cervix, adenosarcomas may be confused with benign cervical polyps clinically and pathologically. As the former often recurs, microscopic differentiation is crucial for further treatment.- - - - - - - - - - ranking = 0.25keywords = gland (Clic here for more details about this article) |
