Abstract
A wide range of endogenous structures, besides cutaneous adnexal structures and anogenital mammary-like glands, can give rise to cystic lesions as well as benign ad malignant neoplasms (Table 12.1). They include Bartholin gland (Bartholin gland cyst, hyperplasia, adenoma, and carcinoma), paraurethral (Skene) gland (skene gland cyst, hyperplasia, and carcinoma), prostatic tissue type of the vulva, canal of Nuck (mesothelial cyst), mesonephric remnant (mesonephric-like or Gartner cyst), endometriosis, and cloacogenic remnants (cloacogenic carcinoma).
Miscellaneous lesions of the vulva will also be discussed in this chapter such as mucinous metaplasia of the vulva, vestibular papillomatosis, granular cell tumor, hidradenitis suppurativa, and epidermolytic hyperkeratosis.
