Selected Cases in Nongynecologic Cytopathology: Inflammatory and Infectious Disease
Benign infectious and inflammatory mimics of mass lesions clinicoradiologically concerning for malignancy are well known. However, certain less common entities may yield hypocellular material on rapid on-site assessment of small biopsy samples. Additionally, microorganisms or features of infection may be identified on material submitted only for cytologic assessment. This session aims to highlight diagnoses which may be subtle on aspirate or exfoliative cytology and core biopsy material. While more sophisticated molecular methods for identification of microorganisms in paraffin-embedded tissue are now being used, they may not yet be widely available. Therefore, traditional ancillary techniques for histochemical identification of microorganisms will also be reviewed.
