Patient's question:
My daughter is 7 years old. There are 2-5 millimeters wide and 5-8 millimeters long, symmetrical white triangles on the upper and lower labia minora, with smooth surfaces and mild itching. She has been seen at two provincial hospitals, one said it was leukoplakia of the vulva, and the other said it was vulvar vitiligo. What is it?Doctor's answer:
Early hyperkeratosis and infiltrative hypertrophy of the skin. The vulvar skin and mucosa may present with localized or diffuse white thickening, resembling leather, raised folds with wrinkles, or scales, and eczematous changes. In the manifestations of leukoplakia of the vulva, the skin color may also change, appearing purplish-red or pale red, or grayish-white, grayish-blue, with clearly defined white keratotic patches mixed in, varying in shape and size. Mixed nutritional deficiencies are present, with a combination of atrophic and hyperproliferative symptoms. The manifestations of leukoplakia of the vulva include significant atrophy of the labia majora, hypertrophy of the clitoral hood, prominent keratosis, coarse ridges on the labia majora, hypopigmentation, and localized thickening or ulcers. The affected skin is rough, with a lichenoid thickening and scratch marks, sometimes developing fissures. Local hypopigmentation is present, with the labia majora and minora generally appearing white.
