Extraskeletal chondroma can occur in the hands, feet, head and neck. This tumor usually presents as a small solitary nodule. The histogenesis of the tumor is controversial, but some have suggested a metaplastic origin. Chondroma of the fallopian tube is very rare. There is only one report in English literature. The origin of this tumor can be subcoelomic mesenchyme of the tubal serosa or mesenchyme of the myosalpinx. We describe a case of chondroma arising from the serosal surface of the fallopian tube with a review of literature. A 30-yr-old woman visited hospital due to left adnexal mass. On operating finding, 2 x 3 cm sized nodular mass was noted on the left tubal serosal area. The excised mass showed multilobulated appearance covered with thin fibrous membrane. The cut surface was solid, grayish yellow, and myxoid with a focal gelatinous area. The microscopic finding showed islands and elongated lobules of mature benign cartilage without cytologic atypia.

Primary carcinoma of the fallopian tube is a rare malignancy of the female genital tract and infrequently diagnosed before an operation. The majority of patients have extensive disease at the time of diagnosis. We have experienced incidentally a case of a carcinoma of the fallopian tube coexisting with a benign cystic teratoma of the ovary in a 25-year-old woman. We report this case with a brief review of literatures.

A patient was admitted for menopause for 2 years and abnormal vaginal bleeding and abdominal pain for 2 months. Gynecological examination revealed uterine atrophy without abnormal findings in the bilateral adnexa. CA125 and CEA levels were normal. The patient underwent laparoscopically assisted vaginal hysterectomy with bilateral salpingo-oophorectomy. Pathological examination of the surgical specimens revealed synchronous primary cancers stage Ia in both the endometrium and the right fallopian tube. The patient then received 6 cycles of chemotherapy with oxaliplatin combined with docetaxel given intravenously and remained alive without evidence of recurrence. Synchronous primary endometrial and fallopian tube cancer is a rare clinical entity, and laparoscopic surgery with postoperative chemotherapy can be considered for stage I patients.

OBJECTIVETo study the serous lesions of the fimbria of the fallopian tube in patients with pelvic serous adenocarcinoma and investigate its significance in the serous carcinogenesis.

METHODSTo observe the morphological features of the fimbria of the fallopian tube in 43 cases of pelvic serous adenocarcinoma (31 cases of ovarian carcinoma and 12 cases of peritoneal carcinoma). Immunohistochemical examination of p53 expression was performed on samples of 69 fallopian tubes of 40 cases.

RESULTSFimbria carcinoma was identified in 44 tubes in 31 of 43 cases. Fourteen of the carcinoma foci were ≤ 5 mm. In 68.3% of the fimbria carcinomas demonstrated involvement of the mucosa. Twenty eight tubes of 20 cases exhibited intraepithelial carcinoma. Twenty three of 44 tubes of the fibria carcinomas showed fimbria adherence and unclear appearance. The early histological changes of the fimbria epithelium included proliferation of local secretory cells, homogeneity, and straightening of the mucous folds. Clusters of tumor epithelial cells or single gland with atypical features floated between mucosal folds were found in 71.4% of the fimbria with intraepithelial carcinoma. The positive expression rate of p53 in the fimbria carcinomas and the fimbria intraepithelial carcinomas were 86.4% and 60.7%, respectively.

CONCLUSIONSFimbria carcinomas is an important component in pelvic serous adenocarcinomas. The fimbria intraepithelial carcinoma is also very common among the cases of pelvic serous adenocarcinoma. The fimbria may be an important primary site of pelvic serous adenocarcinomas.

OBJECTIVESTo study the morphologic changes of fallopian tubal epithelium in patients with ovarian serous epithelial tumors and to explore the relationship between the tubal epithelial changes and tumorigenesis of serous ovarian carcinoma.

METHODSThe fallopian tubes in 79 cases of high-grade serous ovarian carcinoma, 12 cases of low-grade serous ovarian carcinoma, 16 cases of serous borderline ovarian tumor and 11 cases of non-ovarian benign tumors were serially examined under light microscope. Immunohistochemical study with EnVision method was used to detect the expression of p53 and bcl-2 protein in the fallopian tubal epithelium in all cases. The occurrences of secretory cell outgrowth (SCOUT), p53 signature, serous tubal intraepithelial carcinoma (STIC) and serous invasive carcinoma were analyzed.

RESULTSSCOUT in tubal epithelium was observed in 60.8% (48/79) of the high-grade serous carcinoma group, 4/12 of the low-grade serous carcinoma group, 3/16 of the serous borderline tumor group and 2/11 of the non-ovarian benign tumor group (P = 0.001). P53 signature, STIC and serous invasive carcinoma occurred only in the fallopian tubal epithelium of patients with high-grade serous ovarian carcinoma, with the positive rates being 29.1% (23/79), 15.2% (12/79) and 44.3% (35/79), respectively. Of the 23 cases with p53 signature, 17 cases had solitary lesion and 6 cases involved more than two sites. A total of 33 p53 signature positive foci were found, with 22 foci located at fimbria and 11 at ampulla. Bcl-2 expression was demonstrated in 90.9% of those foci (30/33). Of the 12 patients with STIC, 7 cases were solitary and 5 cases involved more than two sites. A total of 18 STIC foci were found, with 16 foci located at fimbria and 2 at ampulla. All of them were positive for bcl-2.

CONCLUSIONSSCOUT is found in fallopian tubal epithelium in patients with serous ovarian epithelial tumors, especially high-grade serious carcinoma. On the other hand, p53 signature, STIC and invasive serous carcinoma of tubal epithelium are observed only in patients with high-grade serous ovarian carcinoma, with a predilection of fimbrial involvement. Correlation exists between SCOUT, p53 signature, STIC and high-grade serous ovarian carcinomas. Bcl-2 and p53 immunostaining is helpful for demonstrating such lesions.
