Rapid on-site cytologic examination of 1500 breast lesions using the modified Shorr's stain.

Background: Rapid on-site evaluation (ROSE) cytology enables sample quality assessment in the procedure room and facilitates the process of examination. While its use for mammary lesions in one-stop breast clinics has been reported, its usefulness as a cytologic diagnostic tool has not been fully explored.

Methods: A total of 1500 examinations of core-needle biopsy imprint/fine-needle aspiration cytology were performed for outpatients with breast lesions.

Rapid cytologic diagnosis of choroidal malignant melanoma by vitreous smear.

The eye is an uncommon subject of cytopathological examination. However, cytopathologic examination may be required for definitive diagnosis in some cases, as malignant tumors of the eye may sometimes be difficult to distinguish clinically from benign disorders. We report a case of malignant melanoma (MM) of the choroid, in which vitrectomy was performed for the initial clinical diagnosis of vitreous hemorrhage.

World wide web-based cytological analysis of atypical squamous cells cannot exclude high-grade intraepithelial lesions.

Objective: It has been reported that the low level of consistency of diagnosis of atypical squamous cells cannot exclude high-grade squamous intraepithelial lesions (ASC-H) in uterine cervical cancer screening using the Bethesda System, indicating the necessity of a large-scale survey. We presented cases cytologically judged as ASC-H on our website and invited our members to give their opinions regarding the diagnosis by voting online. The Web voting results were analyzed and ASC-H was cytologically investigated.

Urine cytology of micropapillary carcinoma of the urinary bladder.

A case of micropapillary carcinoma (MPC) of urinary bladder is presented, in which the urine smear was studied in detail in an attempt to better characterize the cytologic findings of MPC. When the voided urine was examined in low power, cancer cells were scattered in the specimens as compact papillary/spheroidal clusters composed of pleomorphic cancer cells. Solitary carcinoma cells were occasionally observed.
