title: Mucoid cysts of the penile skin.
abstract: A study of 28 patients with mucoid cysts of the penile skin is reported. The lesions were seldom diagnosed correctly, either clinically or pathologically. The distinctive histologic features of the cysts include a lining of stratified columnar epithelium, often associated with intra-epithelial mucous cells and/or mucous glands. These cysts most likely arise from ectopic urethral mucosa sequestered in the penile skin during embryologic development.
