Cytologic diagnosis of Acanthamoeba keratitis. Report of a case with correlative study with indirect immunofluorescence and scanning electron microscopy.

We describe a case of Acanthamoeba keratitis in a 20-year-old woman who wore disposable soft contact lenses. The diagnosis was made initially on the basis of a periodic acid-Schiff-stained corneal smear and subsequently confirmed by scanning electron microscopy and immunofluorescence. The patient was successfully treated with a combination of 0.053% polyhexamethylene biguanide and miconazole. Cytologic study and culture of corneal scrapings is relatively painless and inexpensive and may therefore be used for successful diagnosis and follow-up.

Ciliated bodies in ovarian cyst aspirates.

Ciliated bodies, or detached ciliary tufts, are ciliated fragments of cytoplasm from columnar epithelial cells. In gynecologic cytology they have been observed in cervicovaginal smears and peritoneal washings and very occasionally in fluids from the pouch of Douglas. They occur frequently in the fluids of ovarian cysts. The authors detected ciliated bodies in 30 of 326 ovarian cyst fluid samples (9.20% of cases) taken from 27 patients aged 14-68 years. Ciliated bodies were found in the fluids from both bilateral cysts in one patient and in slides from both former and recurrent cysts in two. Surgery was performed in 14 of the cases, with histologic examination revealing 5 simple serous cysts, 3 paraovarian cysts, 3 serous papillary cystoadenofibromas, 1 serous cystoadenoma and 2 mature cystic teratomas. In the remaining cases the pertinent clinical data, including ultrasound ecography, revealed benign paraovarian and ovarian cysts. The existence of ciliated bodies in the fluids of ovarian cysts indicated the presence of ciliated columnar epithelial cells on the wall of the cysts, which would exclude cysts of follicular origin.
