RT Journal Article SR Electronic T1 Pityriasis lichenoides et varioliformis acuta in pregnancy JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 1127 OP 1129 VO 22 IS 12 A1 Mamdoh A. Eskandar YR 2001 UL http://smj.org.sa/content/22/12/1127.abstract AB Pityriasis lichenoides et varioliformis acuta is an uncommon disease, especially during pregnancy. In review of the obstetric literature, there was no report of pityriasis lichenoides et varioliformis acuta during pregnancy. A 25-year-old female was seen at 24 weeks of gestation for consultation about a cutaneous disease. She was admitted at 30 weeks of gestation because of threatened premature labor, and some active cutaneous papules presented themselves at that time. After the treatment, cutaneous papules remitted. But at 35 weeks of gestation, she had spontaneous labor. Both the mother and infant were doing well at 5 months postpartum. If pityriasis lichenoides et varioliformis acuta exists in the vagina or cervical bone of the uterus, it is due to infections from lymphatic vasculitis and necrosis. It may cause threatened premature labor and premature rupture of the membrane.
