Primary carcinosarcoma of the vagina

Primary carcinosarcoma of the vagina is a very rare tumor, with only eight cases diagnosed as carcinosarcoma in the literature that we are aware of. We recently encountered a case of primary carcinosarcoma of the vagina in a 75-year-old woman. The patient had a history of hysterectomy and bilateral ovariectomy for uterine corpus cancer at 55 years of age. Recurrence of the cancer was suspected 17 years after the operation and irradiation therapy was performed, but the patient died 3 years after the recurrence. Autopsy revealed a mass lesion in the pelvic cavity that originated in the vagina. Histological examination showed that the tumor contained anaplastic carcinoma, rhabdomyosarcoma, leiomyosarcoma and chondrosarcoma components, and it was diagnosed as carcinosarcoma. The histological diagnosis of the uterine corpus cancer was well-differentiated adenocarcinoma, and there was no sarcomatous component. The carcinosarcoma occurred 17 years after the hysterectomy, and it was concluded to be a primary carcinosarcoma of the vagina. This is the first case of primary vaginal carcinosarcoma in which the epithelial and sarcomatous components were clearly identified histologically and immunohistochemically.     

Distribution of a spermicide containing Nonoxynol-9 in the vaginal canal and the upper female reproductive tract

Topical, intravaginal microbicides and spermicides are greatly needed to prevent transmission of sexually transmitted diseases and/or unwanted pregnancies. The development of such compounds is a high research priority. The presumed method of action of existing, or novel, microbicides/spermicides is to provide a chemical barrier to the vaginal epithelium preventing exposure to micro-organisms. Other intravaginal products are used to treat vaginal bacteria of fungal infections. Little is known, however, about the actual or optimal initial distribution and subsequent spread of medications placed in the vagina. We describe a sensitive new technique to quantify the spread of a gel placed in the vagina using magnetic resonance imaging (MRI). Five millilitres of an over-the-counter spermicide containing Nonoxynol-9 was mixed with Gadolinium. MRI was used to quantify spread of the mixture 10 min after insertion with a standard applicator. We demonstrated contiguous spread of gel throughout the vagina. The coverage of material was thicker in the upper vagina than in the lower vagina. We also demonstrated, for the first time, that spermicidal compounds may migrate from the vaginal canal into the endocervix within 10 min of insertion. This finding suggests that topical microbicides/spermicides may act both in the vaginal canal and in the upper female genital tract.     

Characterization of diethylstilbestrol‐induced hypospadias in female mice

The urethral duct and vagina are formed from the urogenital sinus (UGS) during the early neonatal period in mice. Neonatal estrogen exposure results in hypospadias, or the malpositioning of vaginal and urethral openings, with wide cleft clitoris. We sought to characterize diethylstilbestrol (DES) influence on UGS morphogenesis and hypospadias formation. Newborn (day 0) and 1–4‐day‐old female mice (ICR/Jcl) were given (s.c.) oil or 3.0 μg DES. Animals were killed 24 hr later; then hypospadias formation and epithelial apoptosis and proliferation within the developing UGS were assessed. DES did not alter normal UGS morphogenesis by day 1, in comparison with controls. However, hypospadias formation was observed in DES‐treated mice by day 3. In these mice, the distal dorsal urethral duct appeared to fuse with and open into the lower vaginal solid cord region. Further, DES treatment produced a gradual significant increase in dorsal urethral epithelial apoptosis (P < 0.05) just prior to and during fusion and hypospadias formation. DES‐induced urethral epithelial and sinus cord proliferation appeared significantly increased (P < 0.05) and unchanged, respectively, just prior to fusion. By day 5, DES‐treated mice exhibited wide cleft clitoris. In addition, if DES was given on day 3 or 5, a gradual, distinct caudal shift in the vaginal‐urethral junction was observed compared to mice treated on days 0–2. Although hypospadias was not induced when neonates were given DES on day 7, these mice continued to display early vaginal opening. Dose‐response analysis indicated that 0.03 μg DES for 5 days is the lowest known critical dose for hypospadias induction. We have shown for the first time that DES‐induced hypospadias onset may primarily be the result of changes in developing dorsal urethral epithelial cell apoptotic and proliferative activity, and that the location of DES‐induced hypospadias formation is dependent on age at time of exposure.
