RESUMO
Cedar pollen is known as a typical allergen that causes various allergic symptoms in the nasal mucosa, conjunctiva, and skin. However, inflammation of the vulvar mucosa due to sensitization to cedar pollen is not well-known. We experienced two cases in which the detection of cedar pollen during microscopic urine sediment examination led to the diagnosis of allergic vulvovaginitis caused by cedar pollen. The cases involved a 4-year-old girl and a 10-year-old girl. In both cases, the patients presented with chief complaints of pruritis in the vulva and insomnia due to frequent urination during the season of cedar pollen dissemination. Both patients were afebrile. No inflammatory skin changes such as erythema, swelling, or non-purulent discharge from mucous membranes of the vulva were observed. Microscopic urine sediment examination revealed large amounts of shed cedar pollen. The patients' conditions improved after treatment with oral antihistamines and instruction to dry their underwear indoors. Follow-up blood tests revealed high levels of specific anti-IgE antibodies to cedar pollen, thus confirming a diagnosis of allergic vulvovaginitis due to cedar pollen. Cedar pollen can cause allergic vulvovaginitis. Microscopic urine sediment examination is useful, and when combined with specific IgE antibody testing, leads to an appropriate diagnosis. This disease should also be considered in patients with complaints of vulvar discomfort during the season of cedar pollen dissemination.

STUDY OBJECTIVE: To determine the frequency of persistence of vulvar lichen sclerosus (LS) through the pubertal transition and assess if the symptomatology and exam findings differ by menarchal status at onset of symptoms DESIGN: A retrospective cohort study SETTING: Academic tertiary care hospital PARTICIPANTS: Females aged 21 years or younger with a diagnosis of vulvar LS INTERVENTION: None MAIN OUTCOME MEASURES: Menarchal status at symptom onset, presenting symptoms, exam findings, persistence after menarche RESULTS AND CONCLUSIONS: Of the 196 patients who met criteria, 141 were premenarchal and 55 postmenarchal. Of these 55, 36 had postmenarchal symptom onset, and the others had premenarchal symptom onset or LS diagnosis. Over the data review period, 26 patients were followed through the pubertal transition, and 10 (38.5%) had continued symptoms of LS. The premenarchal group (n = 141) was significantly more likely than the symptom-onset postmenarchal group (n = 36) to present with vulvar itching (70.2% vs 52.8%; P = .048), vulvar bleeding (26.2% vs 5.6%; P = .008), and bowel symptoms (16.3% vs 0%; P = .009). The premenarchal group was significantly more likely on exam to have subepithelial hemorrhages (24.8% vs 5.6%; P = .01). The postmenarchal group had more clitoral adhesions (25.0% vs 4.3%; P < .0001) and loss of labia minora (47.2% vs 2.1%; P < .0001). Thirteen postmenarchal patients presented with dyspareunia. This study suggests that premenarchal LS can persist after menarche in about 40% of adolescents and can initially develop in postmenarchal adolescents. Initial symptoms and exam findings differ on the basis of menarchal status. Continued surveillance is recommended.

We here report the case of a 58-year old female patient with no particular past medical history, presenting with a 5-year history of vulvar pruritis, drought and vulvodynia at the Department of Dermatology. Clinical examination showed diffuse porcelaine lesions at the level of the vulva, with a yellowish hemispheric nodular lesion measuring 1 cm in diameter on the whitish plates and some excoriated lesions due to scratching. A skin biopsy was performed at the level of the whitish lesions and at the level of the nodular lesion. Histological examination suggested epidermoid carcinoma for the budding lesion and atrophic vulvar lichen sclerosus for the porcelaine lesions. Surgical treatment was recommended associated with radiation therapy. This study aims to highlight the risk for atrophic vulvar lichen sclerosu degeneration.
