case_images: The cyst was then surgically excised down to the underlying adipose tissue, ensuring complete removal (Figure 2).
case_images: H&E demonstrated acanthotic papillated squamous epithelium with prominent hypergranulosis and whorls of keratinocytes without evidence of cytologic atypia consistent with ruptured verrucous cyst (black arrows)
