The differentiation between cervical intraepithelial neoplasia 3 (CIN 3) and early squamous cell carcinoma (SCC) of the cervix may be difficult in certain situations. Identification of invasion beyond the basement membrane is the gold standard for the diagnosis of the latter. The objective of this study was to determine whether the use of Ki-67 and p53 could help in solving the above dilemma. T...
INTRODUCTION Choristoma is defined as the presence of cells in abnormal locations due to defects during embryological development. The word choristoma implies a neoplasm; whereas heterotopia refers to a displaced tissue without necessarily being a swelling or a neoplasm. Literature contains reports of cartilaginous choristoma in the cervix, endometrium, breast tissue, and oral region. CASE RE...
Spindle cell neoplasms are defined as neoplasms that consist of spindle-shaped cells in the histopathology. Spindle cell neoplasms can affect the oral cavity. In the oral cavity, the origin of the spindle cell neoplasms may be traced to epithelial, mesenchymal and odontogenic components. This article aims to review the spindle cell neoplasms of the oral cavity with emphasis on histopathology. ...
The occurrence of vaginal clear cell adenocarcinoma in young women following exposure in utero to diethylstilbestrol (DES) is now well documented. In addition to this carcinogenic potential. DES has been shown to be teratogenic. In females, the DES-related malformations include vaginal adenosis, transverse ridges of the vagina or cervix and uterine abnormalities. Although no neoplasms have been...
Metaplastic tumors are rare and represent a heterogeneous group of neoplasms showing dominant areas of non-glandular differentiation. Etiology and pathogenesis of this type of lesion in the breast is uncertain. The most common sources of metastatic squamous cell carcinoma of the breast are lung, esophagus, cervix, and urinary bladder. Squamous cell carcinomas may present clinically with inflamm...
This paper describes a case of adenoid basal carcinoma of the uterine cervix, occurring in a woman aged 78 years. In view of the rarity and the limited knowledge of this group of neoplasms, details of the clinical history, the histological appearances, and the histochemical reactions are presented. An attempt is made to define the histogenesis of the tumour and some points on nonmenclature are ...
We report here on the multiple genital tract neoplasms in a 41-yr-old Korean woman with Peutz-Jeghers Syndrome (PJS). The patient presented with lower abdominal pain. Her previous medical history was PJS and breast cancer. Pelvic ultrasound showed a multilocular cyst at the right adnexal region, diagnosed as bilateral ovarian mucinous borderline tumors. An ovarian sex cord tumor with annular tu...
Mesonephric carcinomas of the female genital tract are rare tumors, mainly occurring in the cervix and exceptionally in the uterine corpus. There seems to be a paradigm that the only mesonephric neoplasms arising from the upper zone of the Wolffian system are FATWOs. Indeed, no cases of mesonephric carcinoma of the ovary have been reported in the recent literature. Herein, we describe two cases...
Nonneoplastic and neoplastic cervical biopsy specimens were examined by in situ hybridization to 125I-labeled DNA of herpes simplex virus (HSV), adenovirus, and bacteriophage lambda DNA's, and quantitative hybridization data were obtained using a Video Image Analyser. HSV-specific RNA was detected in 72% of cervical intraepithelial neoplasia, 60% of squamous cervical carcinomas, 2% of nonneopla...
The epidemiological and clinical evidence for various forms of exogenous estrogens altering the risk of neoplasms of the female genital system, breast, and liver are reviewed and evaluated. It is virtually certain that in utero exposure to diethylstilbestrol can cause clear cell adenocarcinomas of the vagina and cervix. There is strong evidence that various estrogens given for treatment of meno...
