Dermalogues: The Dermatology Residents Podcast with Dr. Kerri Purdy

Pregnancy brings major hormonal and immune changes—and the skin often reflects it. In this final episode of season 7 of Dermalogues, Kerri sits down with Dr. Perla Lansang to break down common and high-yield dermatologic conditions in pregnancy, from physiologic changes to PEP (PUPPP) and pemphigoid gestationis.
They discuss how to recognize key patterns, when to biopsy, and how to treat safely—including the role of systemic therapies. The episode also emphasizes a critical takeaway: don’t undertreat pregnant patients—healthy moms are essential for healthy pregnancies.
Dr. Perla Lansang is a staff dermatologist and Associate Professor at the University of Toronto, based at Sunnybrook Health Sciences Centre. She has held leadership roles including Division Director and Director of Undergraduate Education, and is cross-appointed in pediatric dermatology at the Hospital for Sick Children as well as Obstetric Medicine at Sunnybrook. Her clinical interests include pregnancy-related dermatoses and complex medical dermatology.

The conversation also dives into eczema management myths, molluscum contagiosum (including a clever otoscope curettage technique), and how to think through genital lesions in children.
The episode wraps with a clear, experience-based review of infantile hemangiomas, including when to treat, propranolol dosing, duration, rebound, and the role of topical timolol. Packed with practical pearls for residents and practicing clinicians alike.
