What are the Common Types of Histological Samples?

There are several types of samples commonly used in histology:
1. Biopsies: These are small pieces of tissue taken from a living organism for examination. Common types include needle biopsies, punch biopsies, and surgical biopsies.
2. Autopsies: Tissue samples obtained during a post-mortem examination to determine the cause of death and study disease processes.
3. Cytology Samples: These include samples of individual cells or small clusters of cells, such as those obtained from pap smears or fine-needle aspirations.
4. Frozen Sections: Tissue samples that are rapidly frozen to preserve the cellular architecture and are typically used for intraoperative consultations.
5. Formalin-Fixed, Paraffin-Embedded (FFPE) Tissues: These are the most common type of samples used for long-term storage and comprehensive histological examination.
