Histologic Findings

Biopsy samples of neurotic excoriations generally reveal epidermal ulceration with a mild superficial mixed infiltrate and crusts formed from fluid and RBCs. In older lesions, superficial dermal scar tissue and changes of lichen simplex chronicus, such as irregular epidermal hyperplasia with hyperkeratosis, hypergranulosis, and vertical streaking of papillary dermal collagen, may be observed.
