ABSTRACT
Pemphigoid gestationis (PG) is a rare, perinatal, autoimmune, and blistering dermatosis. Only few cases of PG involving hydatidiform moles have been reported. Complete hydatidiform moles are usually evacuated by dilatation and curettage. We report a patient with a massive complete hydatidiform mole that underwent spontaneous expulsion; she subsequently developed PG. A 19-year-old unmarried nulligravid woman was referred to our hospital following excessive vaginal bleeding after an uncertain amenorrheal period. The patient presented with preshock vital signs, severe anemia, and a positive urine pregnancy test. Imaging examinations revealed a massive intrauterine mass (19 × 15 × 10 cm), suggesting a complete hydatidiform mole. She was hospitalized and treated with blood transfusion. Sixteen hours after hospitalization, the massive molar mass underwent spontaneous expulsion and bleeding ceased. Three days after the expulsion, she developed pruritic skin lesions including papules, erythemas, and bullae, which spread over her entire body. Skin biopsy revealed PG and subepidermal blister formation and linear complement C3 deposition along the basement membrane zone, and the serum anti-BP180 antibody level was found to be high on measurement. She was effectively treated with 50 mg/day of oral prednisolone. Her skin lesions disappeared, leaving pigmentation.
ABSTRACT
PURPOSE: The purpose of this study was to investigate whether slow-rate freezing or vitrification is better for cryopreservation of ovary tissues pretreated with gonadotropin-releasing hormone agonist. METHODS: In this nonclinical study performed in rats, leuprorelin acetate was administered to female Wistar rats, aged 6-8 weeks. After confirming arrest of the estrous cycle by examination of vaginal smears, ovarian tissue was cryopreserved by vitrification and slow-rate freezing prior to thawing and autotransplantation. The time required for estrous cycle recovery was assessed from vaginal smears in each group starting from day 1 of transplantation. Estradiol levels were also monitored after transplantation. RESULTS: The estrous cycle recovered after transplantation of ovarian tissue frozen by either method, but recovery was significantly faster after transplantation of vitrified tissue. The estradiol level also recovered by 10 days after transplantation. CONCLUSIONS: Ovarian function was restored after transplantation of tissue preserved by either vitrification or slow-rate freezing after pretreatment with leuprorelin acetate. This method may be applicable for patients scheduled to undergo cryopreservation of ovarian tissue before chemotherapy.
