Pathologic diagnosis and management of flat lesions of urothelium detected with aminolevulinic acid (Hexvix(®)).
Summary of "Pathologic diagnosis and management of flat lesions of urothelium detected with aminolevulinic acid (Hexvix(®))."
The aim of the study was to review the most important flat lesions, to demonstrate the difficulty of classifying several lesions, to introduce to urologists the new problems linked to FD and to suggest new models for accurate analysis. MATERIALS AND
Data about urothelial carcinomas and flat lesions and fluorescence were searched on MEDLINE by using the following keywords: cystoscopy; fluorescence; flat lesion; carcinoma in situ; metaplasia; bladder carcinoma.
No evidence 1 level data was available. Flat lesions are a new challenge in pathology and urology. As urologists have a better sight of bladder lesions with fluorescence diagnosis (Hexvix(®)), pathologists will be asked in the future to evaluate more frequently flat lesions, which are sometimes difficult to classify and for which interobserver agreement is not always evident.
It is essential to determine accurate histologic criteria, able to recognize flat lesions of the bladder and permitting adequate patients' treatment. Further studies with larger cohort of patients are needed to validate preliminary results obtained with fluorescence and to improve our knowledge of the natural history of these tumours.

A number of small lung lesions characterized by small round masses of 2- to 3-mm in diameter. They are usually detected by chest CT scans (COMPUTED TOMOGRAPHY, X-RAY). Such nodules can be associated with metastases of malignancies inside or outside the lung, benign granulomas, or other lesions.
