Purpose: to evaluate the incidence of thermal damage to the specimens excised through large loop excision of the transformation zone (LLETZ) and to determine qualitatively and quantitatively the thermal injury to the ectocervical and endocervical epithelia as well as the influence of the menstrual phase on such process. Methods: we performed a prospective study of 100 patients with high-grade squamous intraepithelial lesions (HGSIL). Thermal damage was subdivided into three grades according to Messing et al¹. Results: thermal injury occurred in all the cases, however, through statistical analysis we found that in 91% of the cases it was insignificant, thus leading to a precise histological evaluation, hence to measure the thermal injury was unnecessary. The grade and extent of thermal damage in excised specimens using LLETZ had no relation to the menstrual phase. The extension of thermal tissue alteration in the endocervical epithelia was 271,6 mu while the extension in ectocervical epithelia was 254,8 mu, showing that the extension of thermal damage is significantly higher in endocervical epithelia. Of the one hundred patients, 80 were in menacme and 20 in menopause correlating the grade and extension of thermal damage with the menstrual state. Conclusion: there was no significant difference in both qualitative and quantitative evaluations. There is no need to measure the thermal damage.

Compound nevus of the uterine cervix is very rare. Benign and malignant melanotic lesions of endo and exocervix have been rarely documented. The present case of compound nevus in the uterine exocervix was found in a 47-year-old woman without gynecologic complaints. Diagnosis was suspected by colposcopic evaluation and confirmed trough histopathological examination. The treatment was concluded with total abdominal hysterectomy based on the possible malignant transformation of these lesions and the difficult patient follow-up.

PURPOSE: to study the influence of the use of oral contraceptives (OC) on the number of Langerhans' cells in women without cervical infection by human papillomavirus (HPV). METHODS: thirty women who presented abnormal cervical cytology and colposcopy-guided biopsy with samples of uterine cervix negative for HPV were selected. The absence of HPV DNA was confirmed by hybrid capture. Langerhans' cells were identified by immunohistochemistry using anti-S100 antigens. The cells visualized in light microscopy were counted using the Cytoviewer software. The nonparametric Wilcoxon rank sum test was employed for statistical analysis. RESULTS: the average number of Langerhans' cells in OC users was 320.7/mm² and in non-users 190.7/mm², this difference being statistically nonsignificant. In the intermediary layer of the cervical epithelium a tendency towards the increase of these cells was observed, with the averages 192.1/mm² for OC users and 93.4/mm² for non-users (p=0.05). CONCLUSIONS: the present study reports a tendency towards the increase in the number of the Langerhans' cells among OC users. This result suggests the OC may induce alterations in the number of Langerhans' cells, but considering the limited number of cases, more studies should be developed for a definitive conclusion.
