Skin disorders of pregnancy

Area of Science:

• Dermatology
• Obstetrics
• Gynecology

Background:

• Pregnancy significantly alters a woman's physiology, impacting the skin.
• Hormonal fluctuations, particularly estrogen and progesterone, are key drivers of these dermatological changes.
• Skin conditions during pregnancy range from common physiological responses to specific pregnancy-related disorders and tumors.

Purpose of the Study:

• To categorize and describe the spectrum of skin disorders encountered during pregnancy.
• To elucidate the physiological mechanisms underlying pregnancy-related dermatoses.
• To provide an overview of common and rare skin conditions affecting pregnant individuals.

Main Methods:

• Review of existing literature on dermatological changes in pregnancy.
• Classification of skin disorders based on etiology: physiological changes, specific pregnancy disorders, and tumors.
• Analysis of hormonal influences on skin conditions like hyperpigmentation and hair growth.

Main Results:

• Skin disorders are grouped into physiological changes (hyperpigmentation, vascular changes, hair cycle alterations), specific pregnancy disorders (common: pruritic urticarial papules and plaques of pregnancy, pruritus gravidarum; rare: pemphigus gestationis, impetigo herpetiformis), and skin tumors (pyogenic granuloma, molluscum fibrosum gravidarum).
• Hormonal surges stimulate melanogenesis, leading to conditions like melasma.
• Malignant melanoma in pregnancy shows comparable long-term survival to the general population, but with a reduced disease-free interval.

Conclusions:

• Pregnancy-associated skin conditions are diverse, stemming from hormonal influences and specific disease processes.
• Understanding these classifications aids in accurate diagnosis and management of dermatological issues in pregnant patients.
• While most skin changes are benign or manageable, vigilance for conditions like malignant melanoma is crucial.
