Objective: We previously reported that oral administration of the selective cyclooxygenase-2 (COX-2) inhibitor etodolac results in antitumor effects in endometrial cancer tissue. Herein, we investigated whether these antitumor effects could be assessed using endometrial cytological findings.

Study Design: Etodolac (400 mg b.

To evaluate a cell-block preparation using glucomannan, which was extracted from Amorphophallus konjac. Ten specimens were centrifuged at 1,500 rpm for 5 minutes, the supernatant was removed; the remnant after the preparation of smear specimens for routine cytological examination was fixed with 20% formalin. The specimen was recentrifuged at 1,500 rpm for 5 minutes, and the supernatant was removed.

It is well known that avian yolk sac is involved in both primitive and definitive erythropoiesis during embryonic development. Definitive erythropoiesis is first detected at about 4-5 days incubation and its maximum activity is reached between day 10 and 15 of incubation, ending between days 18 and 20 of incubation. We confirmed the definitive erythropoietic foci in the chicken yolk sac throughout the 5th to 19th day of incubation by histochemical light and electron microscopy.

We present a case in which a primary cytodiagnosis of Langerhans cell histiocytosis (LCH) of the skull was made using squash preparations. The patient, a 25-year-old male, presented with raised intracranial pressure and decreased visual acuity. Magnetic resonance imaging revealed a large skull lesion with osteolytic features in the left frontal bone.

The cytologic appearance of endosalpingiosis in peritoneal fluid cytology smears has not been extensively described. We report a case of endosalpingiosis in a 29-year-old pregnant female who presented with peritoneal fluid. Dense papillary epithelial clusters with indistinct ciliated cells were found in the Papanicolaou-stained smears.

Background: Pseudosarcomatous fibromyxoid tumor (PFT) of the urinary bladder is an uncommon benign lesion that can involve any site in the bladder. Cellular features of PFT of the bladder are exceedingly rare. We describe the urinary cytology in a PFT patient who displayed numerous papillary fragments that suggested a malignant tumor.

In urinary cytodiagnosis, pathological characterization of atypical cells is sometimes difficult because cells in urine samples tend to be degenerated. To overcome this problem, we adopted serial examination under light microscopy (LM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Five patients with transitional cell carcinoma primarily developed in the bladder, three patients with dysplastic cells, and one patient with metastatic and infiltrative colorectal carcinoma were subjects of the present study.
