A form of chronic vulvitis, sometimes, though indeed quite rarely, met with in girls at this time of life, is inflammation of the external genitals dependent on masturbation. As characteristic signs of this we may observe an elongation of the nymphæ, the clitoris, or the præputium clitoridis, and at the same time on the inner surface of the greatly stretched labiæ we may notice a great increase in the sebaceous glands, so that the yellowish spots formed by these structures may be seen beneath the mucous membrane with the unassisted eye—the mucous surface, indeed, may be slightly uneven in consequence of their enlargement, so that they resemble small retention-cysts. The mucous membrane of the vulva between the margin of the hymen and the nymphæ is moreover, according to _Veit’s_ description of masturbatory vulvitis, often beset with small pointed excrescences, the soft furrow between the clitoris and the external orifice of the urethra being very commonly marked by swelling of the mucous membrane and the presence of these little outgrowths; but sometimes also the parts lying to either side of the urethral orifice may exhibit similar changes. These small structures differ entirely from pointed condylomata—they do not branch, they occur only upon the vulval surface proper, not upon the parts exhibiting the characters of true skin, and they are non-infecting. More particularly, it must be remembered, we find these changes principally in virgins in whom on account of obscure symptoms an examination of the genital organs has been undertaken, and who suffer in addition from nervous and hysterical manifestations. The hymen, when intact, as it usually is in these cases, furnishes objective evidence that sexual intercourse is not the cause of the patient’s trouble, and indeed a distinctly ascertainable cause is hard to find. The patient usually exhibits abnormal sensitiveness and excessive prudery. _Veit_ is of opinion that the association of all these symptoms justifies the diagnosis of masturbation as the exciting cause of the chronic vulvitis; in such cases we may at one time find the mucous membrane pale, but at a later examination fiery red, and we often see a clear, transparent secretion exuding from the ducts of Bartholin’s glands.
