RESUMEN
The coexistence of mucinous ovarian and appendiceal tumors in associated with pseudomyxoma peritonei is well established. But, ovarian and appendiceal mucinous tumors occur without involvement of other organs is unusual. When the two lesions are morphologically similar, it is difficult to determine whether one reflects a metastasis or whether the tumors are independent. The typical synchronous presentation of the ovarian and appendiceal tumors, their histologic similarity, the frequency of bilaterality of the ovarian tumors, the predominance of right-sided ovarian involvement. Adenocarcinoma of the appendix constitutes 0.2 to 0.5 percent of all gastrointestinal tumors and accounts for 6 percent of primary malignant lesion of the appendix. The authors experienced a rare case of synchronous tumor of ovary and appendix in 59 years old female patient who has suffered for 3-4 months from abdominal pain. Pathologic examination of the resected specimen revealed a synchronous mucinous type tumor of vermiform appendix and ovary.

BACKGROUND: Some types of human papillomavirus (HPV) play a major role in the pathogenesis of cervical cancer. Several dozens of studies on the association of HPV with cervical neoplasm have been done since the first detection of HPV 16 and 18 directly from cervical cancer patients in 1983. Approximately 90 types of HPV have been identified so far and the number of oncogenic HPV types is still growing. In this study, we examined the occurrence of oncogenic HPV infections in patients with cervical lesions. Method : Two hundred twenty cervical swab specimens were collected during a 3 year period (1996-1999). Processed specimens were tested for HPV type 16 and 18 by polymerase chain reaction. RESULTS: HPV type 16 was detected in the cervical swab specimens as follows: 19 (51.4%) of 37 cervical cancer patients, 19 (30.2%) of 63 high-grade squamous intraepithelial lesions, 5 (9.6%) of 52 low-grade squamous intraepithelial lesion, none in 6 atypical squamous cells of undetermined significance and 3 (4.8%) of 62 normal cervices. Conclusion : The positive rate for HPV type 16 increased according to the degree of cervical malignancy.
