[Definition of the terms "parakeratosis" and "dyskeratosis" from gynecocytological point of view (author's transl)].

In dermatopathology, parakeratosis and dyskeratosis have always been regarded as exactly defined terms. However, in keratinizing lesions of the portio and vagina, and especially of the vulva, atypical changes have repeatedly been described both within the unkeratinized squamous epithelium and within the stratum corneum. These observations were confirmed by a combined cyto-histological study of the vulva in 464 women. A graduation of cellular atypias was possible. The question therefore occurs as to whether the usual terms para- and dyskeratosis should be supplied with certain additional denotations, or whether they should be sub- or newly classified. Several pathophysiological and etymological considerations would make a new classification seem advisable.
