Pemphigus vulgaris is an immunobullous disease affecting the skin and mucous membranes most commonly during the fifth and sixth decades of life. Its occurrence in pregnancy is rare. We now report two severe cases of the disorder presenting during pregnancy and discuss its potential effects on the foetus and its management in pregnancy.

Pruritic folliculitis (PF) is one of the specific dermatoses of pregnancy the aetiology of which remains unknown. Several theories have been proposed, and the most commonly accepted is that it represents a hormonally induced acne, as seen in patients taking progestogenic steroids. This theory led to the proposition that serum androgen levels may be elevated in this condition, and may be causative. We studied a cohort of 125 pregnant women presenting with a variety of pregnancy dermatoses of whom 12 had PF. These women were compared with 138 pregnant control subjects without a pregnancy dermatosis to determine whether serum androgens were elevated. There was no significant elevation of serum androgens in the 12 cases of PF. There was an overall preponderance of male infants among the PF cases and birthweight of the infants was found to be reduced compared with those of controls. However, the outcome of pregnancy in all cases was favourable implying that PF has no adverse effect on foetal wellbeing.
