Table 1.

Classification of neutrophils and parakeratosis arrangement

Neutrophil arrangement
Scattered	Sparse and isolated neutrophils
Aggregated	Small group of neutrophils between corneocytes
Collections	Densely grouped neutrophils
Parakeratosis arrangement
Scattered	Sparse parakeratotic cells
Lamellar	Multiple layers of parakeratosis disposed adjacently in a small area
Columnar	Multiple layers of parakeratosis vertically disposed
Confluent	Extensive parakeratosis, insignificant areas of orthokeratosis
Parakeratosis quantity
+	Lengthy search is needed to detect parakeratosis
++	Easily detected but requiring classification in high-power view
+++	Easily observable and classifiable in low-power view (×40)
