OBJECTIVE Little attention has been given to hair shafts and squamous cells in peritoneal fluid. To investigate their diagnostic value in peritoneal washing specimens, we reviewed peritoneal washing cytology preparations from 83 cases of ovarian tumors. STUDY DESIGN We reviewed peritoneal washing specimens and histologic sections of 86 cases of ovarian tumors and tumorous conditions, including 22 teratomas, 16 serous adenocarcinomas, 10 clear cell adenocarcinomas, 9 endometrioid adenocarcinomas, 5 cases of endometriosis, 4 mucinous adenomas, 3 serous cystadenocarcinomas and 17 other tumors. RESULTS We observed both squamous cells and hair shafts surrounded by inflammatory cells in 5 of the 22 cases of ovarian teratoma. Rupture of an ovarian teratoma was clinically and histologically found in one of the five cases. Hair shafts were not observed in the other tumors or in nonneoplastic conditions. The diameter of hair shafts in peritoneal washing specimens ranged from 10 to 28.8 microns (average, 16.6), and such hair shafts were present within an ovarian teratoma examined histologically. The diameter of hair shafts from six normal adults who were examined as controls ranged from 61.5 to 118.6 microns (average, 89.4). CONCLUSION Hair shafts and squamous cells surrounded by inflammatory cells in peritoneal washing specimens are a diagnostic clue to ovarian teratoma and can be observed even when rupture of the tumor is not detected clinically or microscopically.
