Welander1 in 1903 reported, as a definite clinical entity, a disease occurring in the form of ulcers about the vulvae and genital region of girls and women who had not been exposed to veneral disease. Over half of his twenty cases occurred in young girls or young women with intact hymen.
Welander's twenty cases were seen by him during a period of seven years, indicating that the disease is not extremely uncommon. Some years later, other authors, such as Lipschutz,2 Tschapin2 and Lenartowicz,3 reported similar cases, including, however, some reports of nonvenereal ulcer that did not correspond to the disease described by Welander. These authors evidently overlooked the fact that veneroid ulcer or the ulcer of Welander is a clear-cut, definite disease, and does not include all the nonvenereal ulcers that may occur about the female genitalia. Fønss4 has recently reported three additional cases.
