We report 3 cases in which endometrial stromal cells exhibited marked nuclear atypia with a symplastic appearance. Two cases involved non-neoplastic endometrial stroma, one within an ovarian endometriotic cyst and the other within normal eu…
A case of müllerian adenosarcoma arising in ovarian endometriosis is reported in which the whole of the mesenchymal component exhibited striking deciduoid morphology, a phenomenon that has not been previously described. The patient was not …
The distinction between a primary ovarian mucinous carcinoma or even a borderline mucinous tumor and a metastatic mucinous carcinoma may be difficult. A constellation of clinical, gross pathologic and morphologic features is used in this di…
A case in which an embryonal rhabdomyosarcoma of the cervix and an ovarian Sertoli-Leydig cell tumour of intermediate differentiation occurred in a 13-year-old girl is described. Although initially considered as a chance association, a revi…
OBJECTIVES: Endometrial polyps are a common cause of abnormal uterine bleeding. Rarely, a hyperplasia, either complex or atypical in type, is identified within a polyp in a biopsy or polypectomy specimen. Currently, it is not known whether …
The propensity for ovarian endometrioid adenocarcinomas to morphologically mimic Sertoli, Sertoli-Leydig, and granulosa cell tumors, is well known. The converse situation, mimicry of an endometrioid neoplasm by a sex cord-stromal tumor, has…
p16 is a cyclin-dependent kinase-4 inhibitor that is expressed in a limited range of normal tissues and tumors. In recent years, immunohistochemistry with p16 antibodies has been used as a diagnostic aid in various scenarios in gynecologic …
AIMS: In the female genital tract CD10 has been used to assist in the evaluation of mesenchymal tumours of the uterus and in determining whether endometrial stroma is present. CD10 positivity has also been shown in cervical mesonephric remn…
AIMS: Recent studies have shown that CD10 is a useful immunohistochemical marker of normal endometrial stroma and of endometrial stromal neoplasms. The aim of this study was to investigate whether CD10 immunoreactivity is present in ectopic…
AIMS: Preinvasive endocervical glandular lesions, termed cervical glandular intraepithelial neoplasia, are increasing in incidence. The distinction of cervical glandular intraepithelial neoplasia from benign mimics, especially tubo-endometr…
Colonic adenocarcinomas composed predominantly or exclusively of cells with clear cytoplasm are extremely rare.1,2 Considerable diagnostic difficulties can arise in distinguishing primary colonic clear cell adenocarcinoma and metastatic car…
Tamoxifen therapy may result in a variety of endometrial proliferative lesions, including adenocarcinoma, and as recently suggested, proliferative changes within endometriosis. This report describes an endometrioid adenocarcinoma arising in…
A case of endometriosis presenting as a mass in the groin of a pregnant woman is described. The mass increased in size during the pregnancy and the radiological features were suspicious of malignancy. Histological examination showed atrophi…
AIMS: Adenomyosis is relatively rare in postmenopausal women but recent reports have described its occurrence in this age group in patients taking tamoxifen. This study describes the pathology of nine cases of adenomyosis in postmenopausal …
An apparently unique intramural uterine lesion is described for which we propose the name adenolipoleiomyoma. On gross examination, a well-circumscribed white intramural mass contained focal fatty areas. Histology showed the mass to be comp…
Two polypoid submucosal uterine lesions were examined histologically and immunohistochemically with monoclonal antibodies to desmin and alpha smooth muscle actin. One case comprised a leiomyoma and the other a polypoid form of adenomyosis. …
