Polymorphic eruption of pregnancy in Mexico

Area of Science:

• Obstetrics and Gynecology
• Dermatology
• Epidemiology

Background:

• Polymorphic Eruption of Pregnancy (PEP) incidence in Mexico was previously unknown.
• PEP typically affects the abdomen, appearing as pruritic papules on stretch marks, and can extend to the buttocks and thighs.
• This study aimed to determine PEP incidence and identify other common pregnancy dermatoses.

Purpose of the Study:

• To determine the incidence of Polymorphic Eruption of Pregnancy (PEP) in the Mexican population.
• To investigate the association between PEP and other dermatoses during pregnancy.
• To assess potential complications or medical management needs related to PEP.

Main Methods:

• A cohort of 217 pregnant women aged 14-45 years was evaluated.
• Comprehensive medical histories and physical examinations focusing on skin and adnexa were conducted.
• Participants were monitored throughout their pregnancies.

Main Results:

• Polymorphic Eruption of Pregnancy (PEP) was identified in 1.38% (3 out of 217) of participants.
• All PEP cases occurred in primigravida women with singleton pregnancies, all delivered vaginally.
• No other gestational pathologies were observed in the study group.

Conclusions:

• The incidence of PEP in this Mexican population (1.38%) is higher than previously documented.
• PEP did not appear to be associated with pregnancy complications or necessitate medical management.
• A potential link between high maternal weight and PEP requires further investigation with larger sample sizes.
