We describe several uncommon contaminants presumably derived from the tap water used in the staining procedure of cytological specimens. We would like to draw attention to the occasional presence of diatoms and fragments of rotifers in cytological specimens. Whilst most of these entities are harmless curiosities, they may cause concern as to their nature and significance.

OBJECTIVE: To desmonstrate the presence of algae in smears and establish their significance. STUDY DESIGN: Microscopic examination of smears stained by the Papanicolaou technique. RESULTS: We found 12 different species of algae, clustered in three categories: Cyanophita (blue algae), Chrysophyta (yellow algae) and Chlorophyta (green algae). CONCLUSION: Algae in smears are infrequently observed, with few bibliographic references. Their presence is due to intrinsic or extrinsic contamination. They may be confused with other structures, such as fungi, Charcott crystals or adenocarcinoma cells.
