Abstract

Epidermal cysts are the most common cysts of the skin. Aconventional epidermal cyst rarely reaches a size of more than 5 cm in diameter. We report on two cases of giant epidermal cyst occurring in the neck. One patient had a cyst measuring 12x9x9 cm and the other patient had a non-pulsatile, dome-shaped lesion in the neck, which measured 6x5x3 cm. The lesions were totally excised. Histopathologically, both were confirmed as giant epidermal cysts.

  Fig. 1 (A) A 61-year-old man with a neck mass. (B) Computed tomographic scan showed a hypodense multilocular mass arrow), which measured 12×9×9 cm, extending to the tracheal area. (C) The cyst was lined by flattened, keratinized stratified squamous epithelium with typical epidermal differentiation (H&E, ×40).

  Fig. 2 (A) A 25-year-old woman with a dome-shaped subcutaneous tumor located on the left lower neck. (B) Computed tomographic scan showed a multilocular cystic mass measuring 6×5×3 cm (arrow). The mass showed expansion toward the trachea. (C) The mass showed a keratinized squamous epithelial lining with the inner surface lined with keratin lamellas (H&E, ×40).
