Reactive bronchial epithelial cells are most characteristically identified by ciliocytophthoria (detached ciliary tufts) with nuclear enlargement but maintained nuclear:cytoplasmic ratio and uniform chromatin. These cells show reactive changes due to inflammation or irritation, with preserved cellular polarity and smooth nuclear membranes. The nuclei may be enlarged with prominent but regular nucleoli, but the chromatin remains evenly distributed without the clumping or irregularities seen in malignancy. Ciliocytophthoria specifically indicates damage to the ciliated respiratory epithelium, commonly seen in viral infections or chronic inflammatory conditions.
